its hook to use grub_uint64_t as addr and size parameters, and rename
to ...

bit of port 0x61. This fixes a possible infinite loop.
High resolution timer support. Implemented for x86 CPUs using TSC.
Extracted generic grub_millisleep() so it's linked in only as needed.
This requires a Pentium compatible CPU; if the RDTSC instruction is
not supported, then it falls back on the generic grub_get_time_ms()
implementation that uses the machine's RTC.
* conf/i386-pc.rmk (kernel_img_SOURCES): Add `kern/time.c',

implementation.
(ieee1275_get_time_ms): New function.
(grub_get_rtc): Now calls ieee1275_get_time_ms(), which does the
real work.
* kern/i386/pc/init.c (make_install_device): Check for `grub_prefix'
instead of `grub_install_dos_part' to determine whether a drive needs
to be prepended to prefix (`grub_install_dos_part' is not reliable,
because it can be overriden when loading GRUB via Multiboot).
* disk/memdisk.c (memdisk_size): Don't initialize.

(grub_arch_memdisk_size): Remove functions.
(grub_arch_modules_addr): Return the module address in high memory
(now that it isn't copied anymore).
* kern/i386/pc/startup.S (grub_memdisk_image_size): Remove variable.
(codestart): Don't add grub_memdisk_image_size to %ecx in LZMA
decompression routine (grub_total_module_size already includes that
now). Don't copy modules back to low memory.
* kern/main.c: Include `<grub/mm.h>'.
(grub_load_modules): Split out (and use) ...
(grub_module_iterate): ... this function, which iterates through
module objects and runs a hook.
Comment out grub_mm_init_region() call, as it would cause non-ELF
modules to be overwritten.
* util/i386/pc/grub-mkimage.c (generate_image): Instead of appending
the memdisk image in its own region, make it part of the module list.
* util/elf/grub-mkimage.c (options): Add "memdisk"|'m' option.

address, install the appropiate relocator code in each bound of
the payload, and set the entry point such that
grub_multiboot_real_boot() will jump to one of them.
* kern/i386/loader.S (grub_multiboot_payload_size)
(grub_multiboot_payload_orig, grub_multiboot_payload_dest)
(grub_multiboot_payload_entry_offset): New variables.

start symbol in non pc platform.
* genmk.rb: Use TARGET_OBJ2ELF to convert native object format to elf.
The following patches are from Christian Franke.
* include/grub/dl.h: Remove .previous, gas supports this only
for ELF format.
* include/grub/symbol.h [__CYGWIN__] (#define FUNCTION/VARIABLE):
Remove .type, gas supports this only for ELF format.
* kern/dl.c (grub_dl_resolve_dependencies): Add check for trailing
nullbytes in symbol table. This fixes an infinite loop if table is
zero filled.
* Makefile.in: Add autoconf replacements TARGET_IMG_LDSCRIPT,
TARGET_IMG_LDFLAGS and EXEEXT.

support for loading host architecture modules, whether we
compile them or not.
* kern/i386/linuxbios/init.c (grub_machine_init): Cast addr to
grub_addr_t before casting it to the void pointer to fix a
warning. Non-addressable regions are discarded earlier.

(check_signature): Don't shadow table_header.
(grub_linuxbios_table_iterate): Cast numeric constants to
grub_linuxbios_table_header_t.
* include/grub/i386/linuxbios/init.h: Add noreturn attribute to
grub_stop().
This fixes a performance issue when pc & gpt partmap iterators
didn't abort iteration even after our hook found what it was
looking for (often causing expensive probes of non-existant drives).
Some callers relied on previous buggy behaviour, since they would
rise an error when their own hooks caused early abortion of its
iteration.

when grub_partition_iterate() returned with non-zero.
* include/grub/ieee1275.h (grub_ieee1275_flag): New constant
GRUB_IEEE1275_FLAG_CANNOT_INTERPRET, GRUB_IEEE1275_FLAG_FORCE_CLAIM
and GRUB_IEEE1275_FLAG_NO_ANSI.
* kern/ieee1275/cmain.c (grub_ieee1275_find_options): Set flag

for human readable format, avoid floating point use.
* kern/misc.c (grub_ftoa): Remove.
(grub_vsprintf): Remove floating point support.
* util/i386/pc/grub-mkimage.c (generate_image): If we included a drive
in our prefix, set install_{dos,bsd}_part = -2 to indicate this can be
skipped later.
(main): If a memdisk was requested, add "(memdisk)" drive explicitly to
the beginning of the prefix.
* kern/i386/pc/init.c (make_install_device): Remove memdisk check.
It is assumed that if we have a memdisk, grub-mkimage has set
grub_prefix to include the "(memdisk)" drive in it.

GRUB_KERNEL_MACHINE_RAW_SIZE. Speed is not as important in this
code as correctness and size.
* kern/i386/pc/startup.S
(grub_biosdisk_get_diskinfo_int13_extensions): When converting

for powerpc & i386-pc. This patch was more so started by Hollis
Blanchard getting multiboot 2 working for powerpc and I added to it
and cleaned it up.
One of the ideas with this patch is to keep everything under one
command for the user. So instead of having a "multiboot2" & "module2"
command, I created a proxy like mechanism so that you have only one
command for both multiboot 1 & 2 ... "multiboot". This is where
"loader/multiboot_loader.c" comes from. I could have integrated things
more but I figure the current approach will less likely break
anything.
So if your OS is multiboot 2 capable, the user would do the following
to load it up from a grub prompt:
grub> multiboot <location of kernel> <kernel args>
grub> module <some image> <multiboot tag> <image arguments>
grub> module <isome mage> <multiboot tag> <image arguments>
grub .....
The other thing that this patch does is it begins to make the
multiboot 1 code a bit more architecture agnostic so IF someone wanted
to implement it on another architecture they can.
A bit of file moving around and definition renaming is also apart of
this patch. I have also taken the time to make sure that it does not
break multiboot 1 loading on i386-pc. But mulitboot 2 may still need a
little more testing and work for i386-pc. Powerpc multiboot 2 has been
heavily tested and does work.
