Hi,
This patch contains several important update for x86_64 efi:
1, Support memory larger than 2G.
2, Fix a bug in efi_call_6 that could cause chainloadering osx to fail.
3, Improve the method to detect frame buffer address and line length
in linux loader.
2009-02-19 Bean <bean12...@gmail.com>
* configure.ac: Check for -mcmodel=large in x86_64 target.
* include/grub/efi/api.h (efi_call_10): New macro.
