Hello all,

  Trying to get the bbt stuff working for diskonchip Mil Plus 32.  Question
in nand_scan_bbt, I pass a erasesize of 8000 (32k bytes).  Is this the
correct size???  If so then I get 256 bytes of mem allocated for this->bbt
but then it fails (out of memory) when I try to allocate 88ooo bytes for the
buffer.  Is this correct?  544K bytes for that buffer.  My proc/meminfo
shows much more memory
# cat /proc/meminfo
        total:    used:    free:  shared: buffers:  cached:

What could be the cause???  Or am I not calculating something right????
