- Move the cache as ram memory to 0x80000 instead of 0xc8000, as the C

- Modify the geode disable_car to ensure the cache is flushed to ram on

With these changes, I get a payload loaded.

_MAINOBJECT #defined. Calls from all other files ended up in nirvana
because the compiler was not able to calculate the address of the
wrapper for the absolute call. The linker tried, but failed miserably.
Use the -combine flag and compile all of initram at once. This enables
GCC to calculate the address of the abscall wrapper, resulting in
working code.
Segher Boessenkool thinks the patched code works only by accident
because GCC has no way to specify generation of XIP code. According to
him, future GCC versions or other circumstances may break the code.
While this patch makes code work for now, it does NOT check whether the
generated code tries to write to memory outside the stack (general
writable data). That will of course fail, but I hope porters are smart
enough to avoid that.

Great work tracking this down! This is okay for now, but we need to look
for a better solution in the future. Counting on porters who may or may
not remember this discussion to avoid something isn't good
future-proofing.
Checking the ELF sections for read-write data and stopping the build
with an error could make this future-proof.

created by parsing the ELF file linuxbios.stage2.o. That way, we avoid
manual specification of the entry point for stage2 code. A few LAR
functions are now unused and can be removed in a following cleanup
session.
Another suggested cleanup would be factoring out a load_all_segments
function, resulting in less code duplication.

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
