BASEADDRESS is located in the 6 lower bits of the CONFIG7 register.
See OMAP 35x Technical Reference Manual, p. 1169.

I'm not subscribed to the linux-omap mailing list but I saw no answer on
this patch and the next one in the archive.

The second one (replaces bitwise operations in board-igep0020.c with
GPMC macros) partly depends on the first one, but can be split so that
part of it can be standalone. Should I do so and resubmit or is it ok
like this ?

Regards,
David.
