This patch is the common/x86 portion of the ARM EFI stub
patchset broken out. These changes support the addition
of EFI stub support for the ARM and ARM64 architectures.
The common code that is now shared in efi-stub-helper.c
is based on code in the x86 stub that has been generalized
to support other architectures.
(Previously these changes were submitted as part of
the "EFI stub for ARM" patch series that included the
common/x86 changes as well as the ARM changes.)
Changes since V4:
* Fix relocate_kernel() on x86/x86_64 by adding alignment parameter.
The alignment was previously read from the setup_header structure
passed to relocate_kernel was was missed when converting to passing
all values as parameters.
* Undo comment reformatting in efi-stub-helper.c
* Fix incorrect comment in eboot.c (obsolete, based on older intermediate
version.
* Include HPA's patch for command line conversion.
Changes since V3:
* Made relocate_kernel() a shared function.
* Made command line unicode to ASCII conversion ASCII
a shared function
* Updated efi_get_memory_map() to return descriptor version,
and updated x86 stub to use it to retrieve final memory map.
* removed min_address argument of efi_low_alloc(), as it is
no longer used.
* Squashed very tiny patch moving EFI_READ_CHUNK_SIZE into
related patch.
Changes since v2:
* EFI bugfix "correct call to free_pages" that patch series
depends on now in mainline
* remove unnecessary zimage_size variable from relocate_kernel()
* correct return types on EFI functions - should be efi_status_t, not int.
Changes since V1:
* Broke up changes to x86 and common code into more patches.

Roy Franz (17):
EFI stub documentation updates
Add proper definitions for some EFI function pointers.
Move common EFI stub code from x86 arch code to common location
Add system table pointer argument to shared functions.
Rename memory allocation/free functions
Enforce minimum alignment of 1 page on allocations.
Move relocate_kernel() to shared file.
Generalize relocate_kernel() for use by other architectures.
Move unicode to ASCII conversion to shared function.
Rename __get_map() to efi_get_memory_map()
generalize efi_get_memory_map()
use efi_get_memory_map() to get final map for x86
Allow efi_free() to be called with size of 0, and do nothing in that
case.
Generalize handle_ramdisks() and rename to handle_cmdline_files().
Renames in handle_cmdline_files() to complete generalization.
Fix types in EFI calls to match EFI function definitions.
resolve warnings found on ARM compile
