From 73480352315a12fdef467402ea41be9ac285e4e7 Mon Sep 17 00:00:00 2001 From: Michael Brown Date: Fri, 19 Apr 2013 13:34:13 +0100 Subject: [libc] Redefine low 8 bits of error code as "platform error code" 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.
