[microblaze-uclinux] Alpha data ADM-XRC II FPGA board with Xilinx virtex2v 3000

1 - there should be no need to touch anything in kernel demo image,
try to get the hardare done first. 

its actually simple, but we had some trouble, so here is the
checklist.

1 try to morph the mbvanilla system MHS to get it working, i.e. fix
UCF change memory controller if needed so on.

if you cant get the mbvanilla morph working get any working system
for your hardware, and morph it to be minimal mbvanilla compatible, 

1 enable I/D cache
2 use barrel hardware divider

you need Timer 2 channels
INTC
and 2 UARTlites

make sure the interrupts work, there is a special mbvanilla test
available from
xilinx.openchip.org
files download (maybe I even update it)

if you dont have UART connectors connect the
RX and TX pins to your parallel port pins and make an RS232C level
adapter at least for
test phase.

verify zou have your RAM at 0x80000000 and
working, find some way to boot,

again, 
xilinx.openchip.org
there is start-up for MMC card bootloader
that uses 4 GPIO pins, the basic code is
working, but the sector read is not done,
so one choice would be to connect a MMC
card to your parallel port and boot from
there,

leave the PCI for later, get the system 
working, then work on PCI
