stand/efiboot: Enable to override `DEFAULT_TIMEOUT`

branches: 1.30.2;
Compensate for src/common/lib/libc/atomic/atomic_init_cas.c losing
the extern declaration of __libc_atomic_init() and instead using a
new one added to src/lib/libc/include/extern.h

That file is outside src/common and src/sys so is unavailable to
kernel builds, so instead make a new include file in src/common
which the kernel can read which contains the needed extern decl
for __libc_atomic_init()

This seems to fix the evbarm builds (maybe others) - but it is
all MUCH TOO UGLY to keep. Someone please make a better fix,
even if that just means reverting rev 1.5 of
src/common/lib/libc/atomic/atomic_init_cas.c
and all of the changes here (the addition to libc/include/extern.h
should be harmless to keep).

Add missing include paths for libz. Not used at the moment although.

adapt to ${CC_WNO_ADDRESS_OF_PACKED_MEMBER}

Simplify CWARNFLAGS to use ${CC_WNO_ADDRESS_OF_PACKED_MEMBER}
which works for both clang and gcc, and remove compiler-specific
equivalents.

bsd.own.mk: rename to CC_WNO_ADDRESS_OF_PACKED_MEMBER

Provide a single variable
CC_WNO_ADDRESS_OF_PACKED_MEMBER

CLANG_NO_ADDR_OF_PACKED_MEMBER
CC_NO_ADDR_OF_PACKED_MEMBER
GCC_NO_ADDR_OF_PACKED_MEMBER

The "version" command prints the current display mode.

Add support for the boot services watchdog and pet it on every block I/O
access. For slow media (like ISO image redirection on Lenovo HR330A BMC)
this is needed because otherwise the default watchdog timeout fires before
we can finish loading the kernel from install media.

add bi-endian support to the libsa ufs reader and enable it in efiboot.

ffs frontends to "ufs.c" now also define ufs_dinode_swap, ufs_indp_swap,
and FS_MAGIC (moved from ufs.c #if segments.) these are used to call
the right (32/64 bit) ffsv1/v2 version.

ufs.c 'struct file' gains f_swapped member. accessors for d_magic,
d_reclen, and d_ino are introduced (they need to be swapped.) sfter
reading an inode from disk, read_inode() may call ufs_dinode_swap().
indirect block number and caches may be swapped.

error handling in ffs_find_superblock() is cleaned up. (size is slightly
reduced on some ports with this part.)

defaults for new defines added to ufs.c. (XXX: we build ufs.c but i think
all the consumers don't use it, and we can stop building it.)

LFS support is not included.

add a cut-down copy of ffs_bswap.c from the kernel.

also enable bi-endian disklabel support in efiboot.

most ports build and sizes compared for platforms that don't enable this
code and all but one saw reduced code size. booted several platforms with

GCC_NO_FORMAT_OVERFLOW variables to remove these warnings.

apply to a bunch of the tree. mostly, these are real bugs that
should be fixed, but in many cases, only by removing the 'packed'
attribute from some structure that doesn't really need it. (i
looked at many different ones, and while perhaps 60-80% were
already properly aligned, it wasn't clear to me that the uses
were always coming from sane data vs network alignment, so it
doesn't seem safe to remove packed without careful research for
each affect struct.) clang already warned (and was not erroring)
for many of these cases, but gcc picked up dozens more.

Remove support for storing settings in EFI environment variables now that
we have boot.cfg support.

Add ACPI support (enable with -DEFIBOOT_ACPI, currently disabled).

When UEFI reports that ACPI tables are available, generate a DTB with
compatible string "netbsd,generic-acpi" and pass this to the booted
kernel.

The DTB contains a /chosen property "netbsd,acpi-root-table" that contains

efiboot: add "setup" command

The "setup" command sets the 64-bit "OsIndications" variable to the value of
EFI_OS_INDICATIONS_BOOT_TO_FW_UI and requests a reboot. On firmware that
supports this, after reboot the user will be presented with the firmware
setup menu.

When printing memory size, don't promote to next unit size unless it is at

print_banner: Print memory size like x86 does

efiboot: Add readahead support.

Reading data through libsa file-systems ends up breaking block I/O
accesses into very small (512-byte or 2048-byte) accesses. This can be
very inefficient, and causes Ampere eMAG w/ BMC image direction to take
_minutes_ to load the install image and kernel. So slow in fact that
the default watchdog timeout will fire before it finishes.

So, when loading big files, optimistically read ahead up to 64KB of data.
Brings the time to boot the install ISO down to around 40 seconds -- still
not ideal but way better than before.

efiboot: Add ASCII art.

branches: 1.19.2;
Implement rndseed support in efiboot and fdt arm.

The EFI environment variable `rndseed' specifies the path to the
random seed. It is loaded only for fdt platforms at the moment.

Since the rndseed (an rndsave_t object as defined in <sys/rndio.h>)
is 536 bytes long (for hysterical raisins), and to avoid having to
erase parts of the fdt tree, we load it into a physical page whose
address is passed in the fdt tree, rather than passing the content of
the file as an fdt node directly; the kernel then reserves the page
from uvm, and maps it into kva to call rnd_seed.

For now, the only kernel that does use efiboot with fdt is evbarm,
which knows to handle the rndseed. Any new kernels that use efiboot
with fdt must do the same; otherwise uvm may hand out the page with
the secret key on it for a normal page allocation in the kernel --
which should be OK if there are no kernel memory disclosure bugs, but
would lead to worse consequences than simply loading the seed late in
userland with /etc/rc.d/random_seed otherwise.

efiboot: Use EFI_BLOCK_IO_PROTOCOL if EFI_DISK_IO_PROTOCOL is missing

UEFI spec says that firmware should automatically add EFI_DISK_IO_PROTOCOL

Fix EFIBOOT_DEBUG build on arm

Implement rndseed support in efiboot and fdt arm.

Since the rndseed (an rndsave_t object as defined in <sys/rndio.h>)

erase parts of the fdt tree, we load it into a physical page whose
address is passed in the fdt tree, rather than passing the content of
the file as an fdt node directly; the kernel then reserves the page
from uvm, and maps it into kva to call rnd_seed.

For now, the only kernel that does use efiboot with fdt is evbarm,
which knows to handle the rndseed. Any new kernels that use efiboot
with fdt must do the same; otherwise uvm may hand out the page with
the secret key on it for a normal page allocation in the kernel --
which should be OK if there are no kernel memory disclosure bugs, but
would lead to worse consequences than simply loading the seed late in
userland with /etc/rc.d/random_seed otherwise.

Network devices can be found as Hardware or Messaging Device Paths,

This fixes PXE boot on implementations with the latter choice, e.g.,
Raspberry Pi 4 UEFI firmware.

MI efiboot: Stop using efi_bootdp after exclusive open for PXE

Once boot device is exclusively opened for Simple Network Protocol,
further access via device path (efi_bootdp) is illegal.

exclusive open, and subsequent access by efi_device_path_depth(),
e.g., causes infinite recursion.

Always do this on arm64 as it won't interfere with KVA and will help us
avoid avoid a very common class of firmware bugs.

branches: 1.12.10;
Update to support EFI runtime outside the kernel virtual address space
by creating an EFI RT pmap that can be activated / deactivated when
required.

Adds support for EFI RT to ARM_MMU_EXTENDED (ASID) 32-bit Arm machines.

On Arm64 the usage of pmapboot_enter is reduced and the mappings are
created much later in the boot process -- now in cpu_startup_hook.
Backward compatiblity for KVA mapped RT from old bootaa64.efi is
maintained.

Adding support to other platforms should be easier as a result.

efiboot: Make FDT support optional on a per-arch basis.

bootaa64: explicitly set GNUEFIARCH and LIBGNUEFI_ARCH to aarch64

Be explicit about building for little endian. This allows efiboot to be
built with the aarch64eb toolchain.

Add module support.

Clean up the banner so it fits in 80 columns and add some extra details
to the "version" command output.

Consistently use ${RELEASEDIR}/${RELEASEMACHINE} instead of
${RELEASEDIR}/${MACHINE} (Paul Ripke)

branches: 1.5.4; 1.5.6;
Make EFI runtime services available to the kernel. Bump version to 1.5.

Enable ACPI support.

Add ACPI support (enable with -DEFIBOOT_ACPI, currently disabled).

When UEFI reports that ACPI tables are available, generate a DTB with
compatible string "netbsd,generic-acpi" and pass this to the booted
kernel.

The DTB contains a /chosen property "netbsd,acpi-root-table" that contains
the physical address of the ACPI RSDP, along with a special /acpi node
with compatible string "netbsd,acpi" for the kernel to attach an acpi(4)
device driver.

Add release target

Add MI EFI bootloader and AArch64 glue.

branches: 1.2.4;
Disable MMU and dcache before jumping to the kernel.

Add MI EFI bootloader and AArch64 glue.

Allow an MD check in prepare_boot and use it on arm64 (aarch64) to check
that, if a big endian kernel is seen, the CPU is capable of supporting BE
data accesses at EL0 via ID_AA64MMFR0_EL1.BigEnd.

branches: 1.6.10;
Align output of "version" command.

Flush from kernel start, not the entry point.

Style fixes, NFCI.

Add a hook for MD specific info to print in the "ver" command. Use this
to print the value of the current execution level in bootaa64.

Add -mfloat-abi=soft so that gcc 8 doesn't emit FP instructions. This
fixes bootarm.efi compiled by gcc 8.

Add efiboot support for 32-bit ARM targets.

Clean and invalidate the full data cache as the armv6_start.S code assumes
that the caches are disabled on entry which armv7_exec_kernel ensures.
When caches are disabled armv6_start.S will invalidate (not clean) the
cache and this can lose u-boot data for the u-boots that now don't
perform their own cache maintenance.

An example of such a u-boot is the banana pro that chuq@ has tried which

Improving things so that the architected caches could remain on would be
better, but that's a much bigger change / set of changes.
