So I take issue with some of the renames. When I see fw_cfg_XXXX I
expect the definition be in fw_cfg.c not in pc.c
Please use prefixes that match the file name -
avoids namespace conflicts and makes it easy to
find files.
This is not to say that the current system is perfect:
we have bochs_bios_init which isn't in bochs.c, should
be pc_bochs_bios_init or whatever.
Thanks!
