bbram access problems

[Geoffroy Stevenne <geof@hellea.com>]

Hi,

We're trying to use BBRAM on a VersaLogic VSBC-6 m-b.  We use the slram
driver and the 2.4.18 kernel.  The problem is that we can't acces the
entire memory of the BBRAM, just the first 64k page.

Other problem: we added to our lilo.conf:

append="slram=BBRAM,0xE0000,+0x10000"

We can write to the BBRAM but we noticed data corruption (not write
operation was done) in this address range.  Is there a way to lock this
memory area?  Is this the right thing to do?

What we need is to mount a filesystem on the entire BBRAM, not just the
first 64k. I can (and wish to) provide more information, test changes,
report bugs, etc. I can read and understand C code but I don't feel
competent in writing drivers on my own.

Thanks for your help,
