 1.5 18-Oct-2018  skrll Provide generic start code that assumes the MMU is off and caches are
disabled as per the linux booting protocol for ARMv6 and ARMv7 boards.
u-boot image type should be changed to 'linux' for correct behaviour.

The new start code builds a minimal "bootstrap" L1PT with cached access
disabled and uses the same table for all processors. AP startup is
performed in less steps and more code is written in C.

The bootstrap tables and stack are placed into an (orphaned) section
"_init_memory" which is given to uvm when it is no longer used.

Various kernels have been converted to use this code and tested. Some
boards were provided by TNF. Thanks!

The GENERIC kernel now boots on boards using the TEGRA, SUNXI and EXYNOS
kernels. The GENERIC kernel will also work on RPI2 using u-boot.

Thanks to martin@ and aymeric@ for testing on parallella and nanosoc
respectively
 1.4 01-Apr-2018  ryo branches: 1.4.2;
Add initial support for ARMv8 (AARCH64) (by nisimura@ and ryo@)

- sys/arch/evbarm64 is gone and integrated into sys/arch/evbarm. (by skrll@)
- add support fdt. evbarm/conf/GENERIC64 fdt (bcm2837,sunxi,tegra) based generic 64bit kernel config. (by skrll@, jmcneill@)
 1.3 10-Dec-2017  skrll branches: 1.3.2;
FDTise RapberryPI support. Thanks for jmcneill for a lot of help with this.

The kernel image that the RPI firmware boots is now netbsd.img in the
kernel build directory.

XXX fdtbus_get_reg needs reworking
 1.2 28-Feb-2015  skrll Initial RPI2 support - it doesn't work yet. The generic timer gets messed
up somehow.

This commit changes the KVA layout of the RPI.
 1.1 26-Jul-2012  skrll branches: 1.1.2; 1.1.4; 1.1.6; 1.1.18; 1.1.20;
Initial commit of support for the RaspberryPI (www.raspberrypi.org)

This is enough for serial console via the gpio header pins and to get to
multiuser.

A huge thank you to Matt Thomas for all his help.

(requested by skrll in ticket #454).

don't mix #define<TAB> and #define<SPACE> in a file.

avoid warning with options PLCOM_DEBUG for INTEGRATOR.

Rename register values. No functional change - same code before and after.

Existing names are prefixed with PL01X_ where they're common between the
PL010 and the PL011. The PL010_/PL011_ prefixes are added where they're
found only on the respective chips.

Replace the simple_lock with a kmutex_t. Update the locking to match
com(4) in the few places it didn't already.

DOH. Replace a line that got accidently deleted in the last commit.

device_t/softc split
struct device * -> device_t
struct cfdata * -> cfdata_t

Add the 'Z' to the 1176 cpu product name.

ok matt@

Fix locking botch introduced in 1.36.

Fix a KASSERT. From/OK'ed by matt@

Fix racy softint dispatch that lead to KASSERT(si->si_active) in
softint_execute

Discussed with matt@. "Looks good to me"

Add the documented ARM11[37]6 Auxiliary control register defines.

Add support for the ARM1176JZS

Add a flag for the lack of LED_ON in HOST_CTL (ti omap3 doesn't do that).

Provide a method for attachments to specify capabilites.

Add support for the PL011 to plcom. Pull across a bunch of fixes from
com(4) while I'm here and do some other tidyup.

Tested on a RaspberryPi.

PL010 not tested.

 1.9 18-Oct-2018  skrll Provide generic start code that assumes the MMU is off and caches are
disabled as per the linux booting protocol for ARMv6 and ARMv7 boards.
u-boot image type should be changed to 'linux' for correct behaviour.

The new start code builds a minimal "bootstrap" L1PT with cached access
disabled and uses the same table for all processors. AP startup is
performed in less steps and more code is written in C.

The bootstrap tables and stack are placed into an (orphaned) section
"_init_memory" which is given to uvm when it is no longer used.

Various kernels have been converted to use this code and tested. Some
boards were provided by TNF. Thanks!

The GENERIC kernel now boots on boards using the TEGRA, SUNXI and EXYNOS
kernels. The GENERIC kernel will also work on RPI2 using u-boot.

respectively
 1.8 03-Aug-2018  skrll Provide and use kern_vtopdiff in KERN_{VTOPHYS,PHYSTOV}. A step towards
generic arm.
 1.7 27-Jun-2018  ryo branches: 1.7.2;
on evbarm/RPI,RPI2, VERBOSE_INIT_ARM had broken.

XPUTC() of evbarm/rpi/rpi*_start.S uses bcm283[567]_platform_early_putchar() and it requires stack.
fixed to allocate stack when starting from rpi*_start.S and a9_mpsubr.S if needed.

to work XPUTC(), need to define VERBOSE_INIT_ARM and EARLYCONS option.
 1.6 27-Jun-2018  ryo remove unnecessary code. .Lmmu_init_table is in same section, and also not r8.
 1.5 03-Mar-2018  skrll branches: 1.5.2;

This commit changes the KVA layout of the RPI.
 1.56 21-Jan-2015  jmcneill Newer Raspberry Pi firmware has changed the framebuffer from BGR to RGB.
The method we use to set the pixel order (vcprop set pixel order) does
not seem to work, nor does querying the pixel order (vcprop get pixel order).

The firmware passes this information to the kernel by adding a
"bcm2708_fb.fbswap" kernel cmdline arg. 0=BGR, 1=RGB. If the parameter is
absent, assume we are running on old firmware and use BGR mode.
 1.55 07-Oct-2014  mlelstv branches: 1.55.2;
fwrev is a timestamp, print in decimal.
 1.54 04-Oct-2014  macallan pay attention to copyin()'s return values
 1.53 03-Oct-2014  skrll Introduce RPI_HWCURSOR and default to off. The existing code causes

 1.44 22-Aug-2014  skrll Remove unnecessary #include
 1.43 25-Jul-2014  jmcneill branches: 1.43.2;
bump VCPROP_MAXCMDLINE to 1024, use this instead of MAX_BOOT_STRING for sizing boot_args, and allow for overriding VCPROP_MAXCMDLINE in kernel config. Fixes cmdline parsing with newer firmware (required for B+)
 1.42 16-Jul-2014  jmcneill need opt_arm_debug.h for VERBOSE_INIT_ARM
 1.41 06-Apr-2014  skrll Re-arrange RPI VM layout and enable __HAVE_MM_MD_DIRECT_MAPPED_PHYS. RPI
kernels now boot again.

I'm not admitting defeat in why there are problems with the
non-__HAVE_MM_MD_DIRECT_MAPPED_PHYS case.
 1.40 01-Apr-2014  skrll branches: 1.40.2;
Trailing whitespace.
 1.39 10-Dec-2013  joerg Move alignment attribute onto the types, not the variable instances.
Drop (unused) packed attribute.
 1.38 15-Oct-2013  skrll Switch to dwctwo(4) from dotg(4) for the RaspberryPi port. This brings
DMA support and (initial) isoc transfer support.

Remove URTWN_DOTG_WORKAROUND as dwctwo doesn't appear to need it.
 1.37 11-May-2013  skrll branches: 1.37.2;
Add attempt at KGDB support from Reiound. I couldn't get gdb to attach
properly, but the kernel was definitely in kgdb_trap and would respond
to $?#3f if typed via tip(1)
 1.36 11-May-2013  skrll Fix up the VCONS_DRAW_INTR support and DDB.

From reinoud.
 1.35 19-Mar-2013  garbled Add a new installer image for Raspberry PI to evbarm

Includes the following major changes:

1) Add new configmenu item to sysinst to allow creation of users at
post-install time.
2) Add an sshramdisk type to evbarm, which is a ramdisk with sshd
enabled, allowing users to install on a headless PI by sshing to the
device with the account "sysinst" password "netbsd" to begin the
installation. (Note, neither the account, nor the ssh setup are copied to
the finalized installation image)
3) Change mkimage to build a boot-only image, without the root filesystems.

Much of the sshramdisk code could be reused on other ports easily.
 1.34 04-Feb-2013  skrll Oops, put back the initialisation of cpu_cc_freq
 1.33 04-Feb-2013  skrll Fix some VERBOSE_INIT_ARM output

 1.30 21-Jan-2013  jakllsch Assume the first ld@sdmmc to attach is the booted device until
possibily-otherwise specified during evbarm cpu_rootconf().
 1.29 19-Jan-2013  jmcneill if the firmware gives us a bad emmc clock rate, ignore it
 1.28 11-Jan-2013  jmcneill allow ukbd to be the console keyboard if genfb is the console display device
 1.27 10-Jan-2013  jmcneill Modify fb attachment so genfb still attaches even if it isn't the console
device. Slight change to cmdline.txt to allow for this:

- console=fb enables fb console, otherwise serial console will be used
- fb=WxH to select a mode, otherwise EDID will be tried and fallback to
default mode (1280x720)
- fb=disable to disable fb completely
 1.26 09-Jan-2013  jmcneill If genfb.type=<int> is passed on cmdline, override the wsdisplay type
returned by WSDISPLAYIO_GTYPE ioctl.
 1.25 09-Jan-2013  skrll Provide the mac address for usmsc(4) as read from the firmware.
 1.24 09-Jan-2013  jmcneill framebuffer only seems to support BGR mode, so request it and set is_bgr property on device when in BGR mode
 1.23 09-Jan-2013  skrll Provide dotg(4) - a driver for the Synposys DesignWare OTG USB IP found
in the RaspberryPI. The driver supports host mode and control, interrupt,
and bulk transfers only at this point.

Heavily based on the FreeBSD driver by Hans Petter Selasky.

Thanks to all who helped. Jared McNeill, Michael van Elst and other.
 1.22 09-Jan-2013  jmcneill genfb support for rpi

interface used by Raspberry Pi's start.elf.
 1.4 16-Aug-2012  matt Move the standard definitions of the {UND,IRQ,FIQ,ABT}_STACK_SIZE to
<arm32/machdep.h>
Move the extern for cpu_reset_address to the same file.
Add cpu_reset_address_paddr.
Kill cpu_reset_v4_MMU_disable.

(requested by skrll in ticket #454).

don't mix #define<TAB> and #define<SPACE> in a file.

avoid warning with options PLCOM_DEBUG for INTEGRATOR.

Rename register values. No functional change - same code before and after.

Existing names are prefixed with PL01X_ where they're common between the
PL010 and the PL011. The PL010_/PL011_ prefixes are added where they're
found only on the respective chips.

Replace the simple_lock with a kmutex_t. Update the locking to match
com(4) in the few places it didn't already.

DOH. Replace a line that got accidently deleted in the last commit.

device_t/softc split
struct device * -> device_t
struct cfdata * -> cfdata_t

Add the 'Z' to the 1176 cpu product name.

ok matt@

Fix locking botch introduced in 1.36.

Fix a KASSERT. From/OK'ed by matt@

Fix racy softint dispatch that lead to KASSERT(si->si_active) in
softint_execute

Discussed with matt@. "Looks good to me"

Add the documented ARM11[37]6 Auxiliary control register defines.

Add support for the ARM1176JZS

Add a flag for the lack of LED_ON in HOST_CTL (ti omap3 doesn't do that).

Provide a method for attachments to specify capabilites.

Add support for the PL011 to plcom. Pull across a bunch of fixes from
com(4) while I'm here and do some other tidyup.

Tested on a RaspberryPi.

PL010 not tested.

Initial commit of support for the RaspberryPI (www.raspberrypi.org)

This is enough for serial console via the gpio header pins and to get to
multiuser.

A huge thank you to Matt Thomas for all his help.

Add RPI to KERNEL_SETS

Get the RPI3 working (in aarch32 mode) by recognising Cortex A53 CPUs.
While I'm here add some A57/A72 info as well.
My RPI3 works with FB console - the uart needs some help with its clocks.

Do invalidate the cache as RPI2 build with Clang can't fetch the memory
config otherwise.
--
Use the VC property mailbox to request the UART clock rate and use it
appropriately
Newer firmwares use 48MHz
--
Disable BSC0 on Raspberry Pi 3 and Zero W boards.
--
Interrupts are enabled before the timer is configured. Ensure that the
timer is disabled when attaching so it doesn't go crazy between the time
interrupts are enabled and clocks are initialized. My RPI3 makes it
multi-user now.

Don't clear CI_ASTPENDING in exception return, do it in ast() instead.
Add basic support for __HAVE_PREEMPTION.
Use atomic ops for ci_astpending if __HAVE_PREEMPTION is defined.
Use kpreempt_disable/kpreempt_enable
Add __HAVE_PIC_HAVE_PENDING_INTRS and define it if __HAVE_PIC_SET_PRIORITY
is undefined (also define in mvsoc_intr.h since their use of the latter is
peculiar). This new define controls whether the pending interrupt logic is
compiled. The GIC doesn't use pending interrupts since it uses the priority
level on the GIC to control delivery of interrupts, thus there can never
be a pending interrupt. The kernel shrinks about 4KB with the removal of
the pending interupt support,
Only if we __HAVE_PIC_PENDING_INTRS do we need the variables to track them.
Add #define __HAVE_PIC_PENDING_INTRS for the non-GIC PICs.
Add a pic_cpus to the softc which specifies which cpus the pic can send
IPIs to. For GIC, initialize pic_cpus to kcpuset_running since it can handle
all the cpus.
Adapt pic to deal with the BCM2836 interrupts.
Move pic_pending_pics, pic_pending_ipls, and pic_blocked_irqs into a
structure and make then per-cpu. There is no global interrupt state anymore.
Use right kcpuset call.
Don't need pic_ipi_sender anymore.
Don't send IPIs to ourselves if sending to everyone.
RPI2 MP support.
Thanks to Matt Thomas for making this possible with his changes to pic.c
Use a bit per IPI type in local mailbox 0 registers. Ok matt@
IPIs should be IPL_HIGH according to rmind@

sys/arch/evbarm/rpi/rpi_machdep.c: revision 1.56
Newer Raspberry Pi firmware has changed the framebuffer from BGR to RGB.
The method we use to set the pixel order (vcprop set pixel order) does
not seem to work, nor does querying the pixel order (vcprop get pixel order).
The firmware passes this information to the kernel by adding a
"bcm2708_fb.fbswap" kernel cmdline arg. 0=BGR, 1=RGB. If the parameter is
absent, assume we are running on old firmware and use BGR mode.

 1.21 18-Oct-2018  skrll Provide generic start code that assumes the MMU is off and caches are
disabled as per the linux booting protocol for ARMv6 and ARMv7 boards.
u-boot image type should be changed to 'linux' for correct behaviour.

The new start code builds a minimal "bootstrap" L1PT with cached access
disabled and uses the same table for all processors. AP startup is
performed in less steps and more code is written in C.

The bootstrap tables and stack are placed into an (orphaned) section
"_init_memory" which is given to uvm when it is no longer used.

Various kernels have been converted to use this code and tested. Some
boards were provided by TNF. Thanks!

The GENERIC kernel now boots on boards using the TEGRA, SUNXI and EXYNOS
kernels. The GENERIC kernel will also work on RPI2 using u-boot.

(requested by skrll in ticket #454).

don't mix #define<TAB> and #define<SPACE> in a file.

avoid warning with options PLCOM_DEBUG for INTEGRATOR.

Rename register values. No functional change - same code before and after.

Existing names are prefixed with PL01X_ where they're common between the
PL010 and the PL011. The PL010_/PL011_ prefixes are added where they're
found only on the respective chips.

Replace the simple_lock with a kmutex_t. Update the locking to match
com(4) in the few places it didn't already.

DOH. Replace a line that got accidently deleted in the last commit.

device_t/softc split
struct device * -> device_t
struct cfdata * -> cfdata_t

Add the 'Z' to the 1176 cpu product name.

ok matt@

Fix locking botch introduced in 1.36.

Fix a KASSERT. From/OK'ed by matt@

Fix racy softint dispatch that lead to KASSERT(si->si_active) in
softint_execute

Discussed with matt@. "Looks good to me"

Add the documented ARM11[37]6 Auxiliary control register defines.

Add support for the ARM1176JZS

Add a flag for the lack of LED_ON in HOST_CTL (ti omap3 doesn't do that).

Provide a method for attachments to specify capabilites.

Add support for the PL011 to plcom. Pull across a bunch of fixes from
com(4) while I'm here and do some other tidyup.

Tested on a RaspberryPi.

PL010 not tested.

Initial commit of support for the RaspberryPI (www.raspberrypi.org)

This is enough for serial console via the gpio header pins and to get to
multiuser.

A huge thank you to Matt Thomas for all his help.

Add RPI to KERNEL_SETS

Remove #if 0 code.

Get the RPI3 working (in aarch32 mode) by recognising Cortex A53 CPUs.
While I'm here add some A57/A72 info as well.
My RPI3 works with FB console - the uart needs some help with its clocks.
--
Do invalidate the cache as RPI2 build with Clang can't fetch the memory
config otherwise.
--
Use the VC property mailbox to request the UART clock rate and use it
appropriately
Newer firmwares use 48MHz
--
Disable BSC0 on Raspberry Pi 3 and Zero W boards.
--
Interrupts are enabled before the timer is configured. Ensure that the
timer is disabled when attaching so it doesn't go crazy between the time
interrupts are enabled and clocks are initialized. My RPI3 makes it
multi-user now.
