If I am understanding things correctly, in 'doc_read_ecc' we
prevent the caller from reading across a 512 byte boundary and
that they cannot read more than 512 bytes at a time. Is this
correct for DoC2xxx devices and should it be the case for NAND
devices as well? I believe that for NAND devices it makes sense
since VFS and filesystems on average assume a 512 byte sector
size. Just looking for agreement on my thought process.

Scrap the limitation. It was OK when the only use of doc2000 was NFTL, but
now it's broken. doc2000.c ought to do the right thing.
