- Patch to efi.c and efibootmgr.c for handling BootXXXX values
using uppercase hex rather than lowercase, per EFI 1.10 spec.

+Rogerio Timmers <rogerio.timmers@hp.com>
+- add option -@ for passing extra variable options in from a file,
+ necessary for setting up some boot entries for Microsoft Windows.

+* Wed Nov 9 2005 Matt Domsch <Matt_Domsch@dell.com>
+- released v0.5.2.2 as v0.5.3, no changes
+
+* Thu Aug 11 2005 Matt Domsch <Matt_Domsch@dell.com>
+- applied patch from Rogerio Timmers which adds a new option -@ <file>,
+ which takes extra variable parameters from <file>, or - from stdin.
+ This lets you pass binary (non-unicode, non-ascii) formatted options to
+ your bootloader.
+- cleaned up Rogerio's patch some.
+- moved definition of _FILE_OFFSET_BITS=64 into Makefile and out of the
+ individual .c files. This fixes a bug reported by Red Flag, where
+ variable data was getting incorrectly set with a 32-bit copy of
+ efibootmgr on a 32-bit kernel.
+- made efi_variable_t.DataSize be an unsigned long to match the kernel.
+ This lets a 32-bit copy of efibootmgr run on a 32-bit kernel. This
+ means you've got to have a 32-bit efibootmgr on a 32-bit kernel, and a
+ 64-bit efibootmgr on a 64-bit kernel, but since efi_status_t is also a
+ long, this was really going to be the case anyway.
+- valgrind caught the app exiting without freeing some malloc'd
+ structures, fix that.
+- v0.5.2.2 released for testing
+
+
+* Fri May 20 2005 Matt Domsch <Matt_Domsch@dell.com>
+- applied patch from Andreas Schwab to properly parse PCI
+ domain:bus:device.fn info in netboot entries. Fixed up return value
+ when creating network boot entries for nonexistant devices, so the
+ creation now fails, rather than succeeding with incorrect data.
+- v0.5.2 released
+
* Tue Mar 08 2005 Matt Domsch <Matt_Domsch@dell.com>
