[microblaze-uclinux] Update - romfs

["John Willlams" <jwilliams@itee.uq.edu.au>]

Hi folks,

A quick update - romfs is now working happily on the microblaze platform.
At boot time I was failing to reserve the area of RAM where the romfs image
resides.  That's now fixed, and it looks good.

Bootup now proceeds to the very end of the init() thread, where it fails
because there is no userland shell application to run.  Next on my list is
elf2flt and userland binary support.

Cheers,

John
