Re: [Ltib] LTIB port for mcp8270

[Stuart Hughes]

Hi Joseph,

LTIB has a number of 603e toolchains that should be usable (glibc and
uclibc), so I think we're okay with those.

The main thing is to get hold of a kernel source and kernel config file.
Once those are available creating the BSP config should be easy.  The
fun starts when you try to boot.  Theoretically if the kernel is a known
good booter, it should "just work", but I think most people know that
the path of true development rarely runs that smoothly.

I'll take a look to see if I can find that PCS BSP, I should have it.
I'll let you know what I find.  This is a project for me "out of hours"
and so I'll do my best, but no promises.  I don't have that hardware, so
hopefully you can help with the testing.

Regards, Stuart
