Re: [Ltib] porting big-endian to little-endian

[Stuart Hughes]

Hi Eder,

Your best bet is to start with a BSP that is closest to the target you
want to build for.  There are some in the public LTIB: mpc8349itx,
mpc8360epb, mpc837xemds.  However I think on Freescale's website they
have some ISO images for mpc831x processors that would be better.

Fundamentally once you have this, you should have a good
toolchain/userspace to build.  You then need to find a kernel source
that is either close or already ported.  Similarly you need a close
u-boot target (check in the configs in the latest source tree).

Good luck.

Regards, Stuart
