loader: store FW CFG ROM files in RAM
RAM MRs including ROM files in FW CFGs are created
and named using the file basename.
This becomes problematic if these names are
supplied by user, since the basename might not
be unique.
There are two cases we care about:
- option-rom flag.
- option ROM for devices. This triggers e.g. when
using rombar=0.
At the moment we get an assert. E.g
qemu -option-rom /usr/share/ipxe/8086100e.rom -option-rom
/usr/share/ipxe.efi/8086100e.rom
RAMBlock "/rom@genroms/8086100e.rom" already registered, abort!
This is a regression from 1.6.
For now let's keep it simple and just avoid creating the
MRs in case of option ROMs.
when using 1.7 machine types, enable
option ROMs in RAM to match that version.
