Hello,
This includes the previous Mainstone re-org patch I sent earlier plus flash
support.
This adds two 32MiB flash devices. Mounts from mtdblock2 on flash device 0
fine at boot.
I did some guesswork on the flash initialization to make it build with
Laurent's -disk patch. Please check if it is still correct.
works fine.
Note that both chips get mapped at the same offset in phys_ram_base,
I'm quite sure this is a bug and not intentional? It may corrupt data
if the OS reads from both chips. I wanted to convert mainstone.c to
use qemu_ram_alloc like other pxa boards but I want to make sure this
is not intentional.
The value of mainstone_rom indicates this too.
Sorry, mainstone_rom is not related to this issue, but that means that
the ram_size check allows too low values and qemu may crash. It also
means that the two flash chips *and* the ROM all overlap. I think
gumstix.c registers the flash correctly, you may wnat to look in it.

will do.
I seem to remember that the two mappings are mutually exclusive and
possible controlled by an external switch.. I will need to double check
that.
sorry for the trouble.
