[microblaze-uclinux] we have a shell!

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

Hi folks,

Great news, after a couple of days of detailed and painful debugging, 
I've nailed a couple more bugs that were holding me up.  So, now I can 
boot the kernel all the way through init and to a simple shell (sash)!

Boot log attached as proof!  Note this boot log is from a boot into 
single user mode - no init scripts running etc but I've tested that and 
it seems to work OK.

Next I need to spruce up the console driver to accept keystrokes via the 
console_uart (enable interrupts and so on) - am working on that now.  I 
sincerely hope to have an interactive shell session going within the 
next day or two.

You'll need to do a CVS update on the kernel directory (uClinux-2.4.x), 
and also I'll have to distribute a modified version of the elf2flt 
utility (one of the bugs was in there).  I'll prepare some detailed 
instructions shortly.

We're almost at the point where "regular" linux/uClinux people can start 
to get involved - kernel hacking (and following my kernel port!) not 
required.

Regards,

John
