* [libc] Redefine low 8 bits of error code as "platform error code"Michael Brown2013-04-192-0/+242
The low 8 bits of an iPXE error code are currently defined as the closest equivalent PXE error code. Generalise this scheme to platforms other than PC-BIOS by extending this definition to "closest equivalent platform error code". This allows for the possibility of returning meaningful errors via EFI APIs. Signed-off-by: Michael Brown <mcb30@ipxe.org>
