Major rework of the ia64 loaders. The two primary objectives are: 1. Make libefi portable by removing ia64 specific code and build it on i386 and amd64 by default to prevent regressions. These changes include fixes and improvements over previous code to establish or improve APIs where none existed or when the amount of kluging was unacceptably high. 2. Increase the amount of sharing between the efi and ski loaders to improve maintainability of the loaders and simplify making changes to the loader-kernel handshaking in the future. The version of the efi and ski loaders are now both changed to 1.2 as user visible improvements and changes have been made.

Sync the EFI headers with version 1.10.14.62 of the Intel sample EFI implementation. This re-introduces C99 style comments that previously were replaced by original C comments.

Pass the HCDP table address to the kernel. If no such table exists, NULL is passed. The address of the HCDP table can be found by iterating over the configuration tables in the EFI system table. To avoid more duplication, a function can be called with the GUID of interest. The function will do the scanning. Use the function in all places where we iterate over the configuration tables in an attempt to find a specific one. Bump the loader version number as the result of this. Approved by: re (blanket)

void *efi_get_table(EFI_GUID *tbl);
Change the startup code to fix a memory leak and to allow us to accept load options (=command line options). The call graph changes from *entry*->efi_main->efi_init, where efi_main is the EFI equivalent of main to *entry*->efi_main->main, where main is what you'd expect. efi_main now is what efi_init was. The prototype of main follows that of C. The first argument is argc and the second is argv. There is no third argument. Allocation of heap pages is now handled by the EFI library and it now deallocates the pages when main() returns or when exit() is called. This allows us to safely return to the boot manager (or EFI shell) without leaks. EFI applications are responsible to free all memory themselves. Handling of the load options is a bit tricky. There are either no load options, load options in ASCII or load options in Unicode. The EFI library will translate the ASCII options to Unicode options as to simplify user code. Since the load options are passed as a single string (if present) and main() accepts argc and argv, the startup code also has to split the string into words and build the argv vector. Here the trickiness starts. When the loader is started from the EFI shell, argv[0] will automaticly load the program name. In all other cases (ie through the boot manager), this is not the case. Unfortunately, there's no trivial way to check. Hence, a set of conditions is checked to determine if we need to fill in argv[0] ourselves or not. This checking is not perfect. There are known cases where it fails to do the right thing. The logic works for most expected cases, though. This includes the case where no options are given. Approved by: re (blanket)

o Introduce efimd_va2pa() to translate addresses in efi_copy{in|out}() and efi_readin(). This removes MD code from copy.c. o Don't unconditionally add pal.S to SRCS. It's specific to ia64.
