[microblaze-uclinux] New port

[Scott Thibault <thibault@xxxxxxxxxx>]

Hello,

I'm working on a new port (V2Pro board) and I have couple of questions.
I've built an EDK project like the mbvanilla_net project.  The differences
are I have 64MB of SDRAM instead of DDR, no flash, no gpio, and only 8KB of
BRAM.  I've tested the memory with a simple test application and all is
okay.

Next, I tried downloading an image.bin.  After waiting a long time (jtag
connection), it finish and started to boot but failed with:
	VFS: Cannot open root device "" or 00:00
	Please append a correct "root=" boot option
	Kernel panic: VFS: Unable to mount root fs on 00:00

Any ideas what the cause might be?

Other questions are:
How should I increase memory to 64MB?
Is the system dependent on the flash in anyway?
Do I need to disable any options since I have no flash?
Where is the Ethernet IRQ defined (I see the URT/TIMER in mbvanilla.h)?
As far as the BRAM is concerned, it doesn't seem to be used for anything is
it?

Thanks,
