[U-Boot-Users] MIPS LE build problems

Dear Thomas,
I always wondered what exactly was the reason why I was not able to
build the dbau1x00 targets (especially the little endian dbau1550_el
target using the ELDK toolchain). Also, I always wondered about the
reference to a non-exitent cpu/mips/little/liblittle.a library.
Is ther ea special reason for the current settings of build options
for the dbau1x00 targets?
Attached below is a patch which makes all dbau1x00 targets build fine
with the current ELDK, and I believe these settings are more correct
than the previous ones.
If you don't protest I would like to merge this patch into the public
source tree?
Best regards,
Wolfgang Denk

-------------- next part --------------
Fix dbau1xxx (= MIPS big and little endian) build options.
Incorrect gcc options (big endian -BE switch) were used for
dbau1550_el which is a little endian build; also get rid of reference
to non-existant cpu/mips/little/liblittle.a library
