Unfortunatelly, I have to deal with the file-system from
the FPGA as well - as from the Linux.
Probably I have not enough room to implement ext2/ext3
in the FPGA.
Anyway - I will see what...

Actually - I have my driver-skeleton up, and I can now load
firmware into the card.
That's a movement ... but lot more to do.

I don't know why AMCC said that stupid 0x26 instead of 0xE6...
Others seemed OK - and the LED's blinking :-)
