800x480 Display broken on i.MX25 with MMU

[Eric Bénard]

Hi,

on an i.MX25, it seems that 3100ea14668853aeedae85ec83e3536b59ba7728
broke framebuffer usage with a 800x480 display when MMU is enabled :
about 1/4 of the display (at the bottom) is garbage.

v2011.08.0 : it works fine

v2011.09.0 : it fails

disabling MMU makes it work again in v2011.09.0

then in v2011.09.0 it works with MMU enabled after reverting the
following commits :
43ebdba64a6e1c12fe58aa57e905cfdcef922126
56c379160b9f0b52efcaaefce9adb6121d5865d7
a6c333c7f2dbe49189dd5343da3c921659e88cbf
3100ea14668853aeedae85ec83e3536b59ba7728

So it seems something was broken during MMU rework and I don't yet know
what : Sascha do you have an idea ?

Thanks,
Eric
