Finally, the Syslinux 6.00 release is out. This release includes support
for booting from EFI, both from disk-based media and over the network
via PXE. Thanks to everyone who has been testing this out.
There are some EFI bugs that I'm aware of,
* booting Linux kernels without CONFIG_RELOCATABLE doesn't work
* 64-bit syslinux.efi cannot boot 32-bit kernels and vice versa
* displaying of Fn files messes up the console
Please do test out the release and report any regressions. I'm
particularly interested to hear about any problems with the BIOS code,
which will be a result of introducing the 'firmware' abstraction that
allows the BIOS and EFI backends to coexist.

Shao Miller (1):
efi: Fix a memory map buffer release
chandramouli narayanan (13):
Patches here support 32bit and 64bit environment.
This patch implements the setjmp/longjmp, memcpy, memmove, memset and mempcpy functions as appropriate for the architecture. The code came from klibc. com32/lib has i386 and x86_64 sub directories implementing the code.
Architecture dependency in LZO data compression library in subdirectory core/lzo/ is taken care to be able to build fo i386 for x86_64.
EFI boot loader in efi_boot_linux() now supports booting i386 and x86_64 linux kernels. Main x86_64 changes are in a) setting up high part of EFI system table and memmap b) loader signature c) setting up jump vector to hand off to kernel.
The ELF module load and the utility library routines fully support lookup, resolution and relocation of symbols for both ELF32 and ELF64 environments. With this, syslinux.efi built for i386 and x86_64 can load the respective native command modules dynamically. The architecture dependent files are split into respective subdirectories (com32/lib/sys/module/i386 & com32/lib/sys/module/x86_64) for the build environment to pick.
This is a giant patch that splits the linker scripts for libraries, modules and executables into the architecture-dependent scripts to facilitate building syslinux modules/executables for i386 and x86_64 environments. The x86_64 linker scripts are derived from the earlier i386 counterparts.
The make files have undergone changes to support both i386 and x86_64 platforms. Pertinent changes are sprinkled through *.mk and Makefile in the syslinux tree.
This patch implements architecture-dependent code in memdisk to support for i386 and x86_64. The memcpy, memset and memmove routines originated from klibc.
The assembler directive in memdump/code16.h is fixed for x86_64 build.
Archicture-dependent get_cpuid in sysdump/cpuid is fixed.
Console input initiated by com32 modules and sample programs hang on both i386 and x86_64. The issue is traced to the implementation of get_key() underlying firmware. For stdin file descriptor, the console read finally resolves to __rawcon_read() implemented in com32/lib/sys/rawcon_read.c. This file is firmware-dependent and currently has only BIOS-specific code As a temporary fix, in EFI, __rawcon_read() is implemented using getchar(). The implementation of getchar() in EFI is guided by the firmware structure that points to efi_getchar(). With this temporary fix, com32 command modules that wait on console input work.
efi_getchar() should wait for the event before reading keystroke. On an efi64 platform, it didn't work without wait. It needs further debugging to ascertain the fix.
This is the first cut checkin for GOP supporting the menu subsystem. For the initial cut, all of vesa code is dropped into vesa/efi with code buildable for EFI with a build option. There is VESA only code that is in the efi subdirectory as well that should go away eventually. Other files not dependent on EFI or not relevant to EFI need to be removed as well (e.g. i915resolution.c).
