Hi,
Thanks for your feedback !

My U-Boot patch is only secondary: the flash emulation can simply be
used by the Linux kernel, for example.
In my U-Boot patch, the only thing related to the flash is the switch
from a Versatile-specific flash driver to the generic CFI driver. The
rest of the modifications have nothing to do with the flash, they are
just hacks/workarounds to get U-Boot to run under Qemu and are not
related in any way with this patch (network driver things and timing
things).
These issues should be worked out as a separate Qemu patch if we really
want Qemu to run an unmodified U-Boot for the Versatile platform, but
IMO, that shouldn't prevent the flash emulation from being merged in
Qemu.
Sincerly,
Thomas
