load_elf: replace the address addend by a translation function
A few machines need to translate the ELF header addresses into physicaladdresses. Currently the only possibility is to add a value to theaddresses.

Remove conditional rom loading support
Commit c2039bd0ffce8807e0eaac55254fde790825fa92 made rom loadingautomatic for non-PC architectures. Remove now mostly unusedconditional rom loading support.

roms: minor fixes and cleanups.
Changes: - Drop extra file argument from rom_add_file(). - Drop fw_dir check in do_info_roms, we allways have a dir name. - code style fixes.

roms: rework rom loading via fw
This patch changes the way rom loading via fw_cfg is handled.Instead of having pc_init1() call a function which passed allroms to the firmware config we simply pass a pointer to fw_cfgto the rom loader.
Advantage: loading roms via firmware works also for devices which...
loader: more ignores for rom intended to be loaded by the bios
Similarly to what has been done in e405a2ba91b68817cae2a428de55fe9616a4cf37,ignore rom intended to be loaded by the bios in find_rom() and rom_copy().

Don't load options roms intended to be loaded by the bios in qemu
The first such option rom will load at address 0, which isn't very nice,and the second will report a conflict and abort, which is horrible.

Multiboot support: Fix rom_copy
ROMs need to be loaded if they are anywhere in the requested area, notonly at the very beginning. This fixes Multiboot with ELF kernels thathave more than one program header.

roms: allow roms to be loaded at address 0
It was possible to load roms at address 0, but commit632cf034b401cdd01dae253a8b577fe518e37654 started to forbid that, whichbroke at least ARM versatile.
roms: use new fw_cfg file xfer support.
roms: use fw_cfg for vgabios and option rom loading, additionally todeploying them the traditional way (copy to 0xc0000 -> 0xe0000 range).
roms: remove option rom packing logic
Now that we load the option roms via fw_cfg, we can stop copyingthem to the 0xc000 -> 0xe000. The patch does just that.
Also the rom loader gets simplified as all remaining users of therom loader load the bits at a fixed address so the packing and...

Fix loading of ELF multiboot kernels

Introduce rom_copy
We have several rom helpers currently, but none of them can get uscode that spans several roms into a pointer.
This patch introduces a function that copies over rom contents.
