RevisionDateAuthorComments
 1.23  03-Aug-2023  mrg ignore "-Warray-bounds" for various low level platform code that knows
how something is setup but technically is undefined behaviour. the
most common here is "extern int end;" and then using offsets of "&end"
that are outside the bounds of this 4-byte integer.

these uses are almost certainly all OK in reality.

found by GCC 12.
 1.22  20-Apr-2023  skrll Provide a shared pmap_devmap implementation and convert all pmap_devmap
arrays to use DEVMAP_ENTRY{,_END}
 1.21  11-Oct-2021  rin alloc_pages: panic if allocating beyond KERNEL_TEXT_BASE.
 1.20  11-Oct-2021  rin Wrap multi-line macros with ``do { } while(0)''.
 1.19  11-Oct-2021  rin Fix build with DEBUG_BEFOREMMU.
 1.18  17-Aug-2021  andvar fix multiplei repetitive typos in comments, messages and documentation. mainly because copy paste code big amount of files are affected.
 1.17  18-Apr-2020  skrll PMAP_DEBUG has been deleted on arm
 1.16  18-Apr-2020  skrll Trailing whitespace
 1.15  16-Jul-2019  skrll branches: 1.15.8;
Consistently use vaddr_t as initarm and friends return type.

Makes no difference to binaries except for aarch64 where it's required
 1.14  16-Jul-2019  skrll KNF
 1.13  28-Oct-2018  skrll Fix a commit
 1.12  06-Nov-2017  christos branches: 1.12.2; 1.12.4;
Cleanup and clarify the ELFSIZE mess:

We now have 2 variables automatically set in elf_machdep.h:

ARCH_ELFSIZE: the size for userland binaries
KERN_ELFSIZE: the size for the kernel binaries

DB_ELFSIZE has been deleted and KERN_ELFSIZE should have always the
same values DB_ELFSIZE used to have.

In sys/exec_elf.h, if ELFSIZE is not set, it is set to KERN_ELFSIZE
for the kernel and ARCH_ELFSIZE for userland. These defaults should
eliminate the need for most manual ELFSIZE setting.
 1.11  22-Dec-2016  cherry switch all ports to use uvm_init.c:uvm_md_init()

uvm_setpagesize() is now subsumed within this funciton.
 1.10  13-Sep-2014  matt branches: 1.10.2; 1.10.4;
Use paddr_t for msgbufphys
 1.9  10-Mar-2014  skrll Avoid unused variable warning by borrowing sa1_cache_clean_addr briefly
 1.8  18-Aug-2013  matt Fix <arm/locore.h> lossage
 1.7  22-Sep-2012  matt branches: 1.7.2;
Don't use an asm in pmap_activate to update the TTBR, use cpu_setttb instead
but add a second argument to it to indicate whether the TLB/caches need to be
flushed. Default cortex to pmap_needs_fixup = 1. But check the MMFR3 field
to see if the fixed can be skipped.
Use a cf_flag bit 0 to indicate whether the A9 L2 cache should disable (bit 0 = 1)
or enabeld (bit = 0).

With these changes, the A9 MMU can use traverse caches to do MMU tablewalks
Also, make sure all memory has the shareable bit for the A9.
 1.6  16-Aug-2012  matt branches: 1.6.2;
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.
if cpu_reset_address is NULL, then the MMU will be disabled.
 1.5  29-Jul-2012  matt Fix more -fno-common fallout.
Move more variables to common locations.
 1.4  31-Mar-2012  nonaka Add support kloader(4) for PXA2X0.
 1.3  19-Jul-2011  dyoung branches: 1.3.2; 1.3.6;
Change <machine/bus.h> to <sys/bus.h> throughout.

Split bus.h -> bus_{defs,funcs}.h.

Mark hpcarm/bus.h obsolete.
 1.2  26-Jun-2010  tsutsui branches: 1.2.2;
If options RTC_OFFSET is not specified use bootinfo->timezone passed
by hpcboot.exe as well as other hpc* ports. Noticed by uwe@.
Also comment out options RTC_OFFSET=0 lines and note about this
in kernel config files. Tested on WS003SH.
