NAK -- no ARM target needs bios emulation, so basing the #define on ARM requirements is incorrect.
Actually, ARM targets build drivers/bios_emulator/libatibiosemu.o as the result of an overlook in ./Makefile where this object is compiled unconditionally.
A git grep CONFIG_BIOSEMU seems to indicate only a handful of PowerPC targets need bios emulation; I suggest doing a V2 of this patch where the object is built only for PowerPC, and the #define is removed.
So the patch was initiated by the discussion here: http://marc.info/?l=linux-arm-kernel&m=136399798826572&w=2
I am looking into getting biosemu up on ARM for the PCI-equipped ARM boards, but admittedly I have no idea where it'll go.
But this can surely wait until I have a series that can be run as well.
Indeed: when some real ARM target needs biosemu, then yes, this patch will make sense as part of the series that introduces this target.
Yours, Linus Walleij
Amicalement,
