Dear All,
We did not find the support for ARM940T architecture in the u-boot sources.
Is there any ARM cores which are equivalent to ARM940T? Do we need to
modify any existing ARM core files to support ARM940T?
Regards,
Srinidhi.

You should start a new CPU support (say in arch/arm/cpu/arm940t) based
off what exists for the ARM920T, which has the same ARM9TDMI and differs
from ARM940T in that the 920T has an MMU while the 940T has a protection
unit instead.
Whatever code you find common to 920t and 940t you could possibly put in
a common ARM9TDMI location. If eventually most of the code is common,
maybe a single arch/arm/cpu/ subdirectory could cater for both 920t and
940t.
