There is no easy way to check extension ROMs in the current machine for
correct signatures, but you could copy out the memory between 0xc0000 -
0xf00000 from /dev/mem and search for extension headers in it (see the
code in pci_rom.c).

code as a result. While I'm at it, improve the LAR segmentation
abstraction. Stage 1 code should not have to care about internal
representation of segments, that knowledge belongs into lib/lar.c.
Constification of most function parameters in lib/lar.c led to a few
other now obvious code removals.

manual specification of the entry point for stage2 code. A few LAR
functions are now unused and can be removed in a following cleanup

Another suggested cleanup would be factoring out a load_all_segments

and create a valid LAR header with an entry value. This will fix the
problems Ron is having on the ALIX 1C and probably allow it to boot.
It also sets the text base of the .o to 0, instead of whatever wacky
value gld is choosing, so all platforms will have the same value.
Get away from worrying about potential gld bugs, now and in the future.
As added benefit, we obsolete a lot of code without introducing
new code.
Qemu target entry point debugging has been added to be able to spot
problems with entry points in the future.

Improve LAR code documentation and reorder variables in one assignment

number from ELF as segment number in the file. This works nicely when
there are no skips (e.g. not PT_LOAD segments, which are discarded).
If one segment is skipped, we get a bump:
normal/payload0/segment0 (27288 bytes, lzma compressed to 14506 bytes @0x64c0)
normal/payload0/segment2 (211136 bytes, lzma compressed to 70905 bytes @0x9dc0)
The LAR loader wont load segment2, and in this particular case, grub2-lb
will only boot into rescue mode (segment0 contains it).
Attached patch adds a counter for segment number in the LAR utility to
solve this bug:
normal/payload0/segment0 (27288 bytes, lzma compressed to 14506 bytes @0x64c0)
normal/payload0/segment1 (211136 bytes, lzma compressed to 70905 bytes @0x9dc0)
Also the eagle eyed can see that I merged in Uwe's multiple-payload
patch into current stage1, which includes the segment support. And this
means that grub2-lb without any hacks works when loaded from LAR segments.

one common file.
The first is the noelf option, which is a simple
modification to look for payloads in the form
payload/segmentX where X is a number.
The segments are assumed to be contiguously numbered and the code
steps when the first search fails (i.e. if 0 and 1 are there, and 2
is not, the code stops and will not try to find 3).
The lar code will use the loadaddress to load the segment. Currently,
the lar code will not run each loaded segment, but we need to consider
this for uwe's lbmenu work. Consider this implementation somewhat
preliminary until we integrate lbmenu. There is the complex issue of
interdependent segments, as in the kernel, where no single segment
can run until all are loaded.
The second is the fix for improperly wrapping to 0 when
searching the LAR.
This has been tested with filo and BOCHS.
