The DiskOnChip hardware driver hasn't been used much with anything other
than NFTL. It appears not to do a full read if you ask it to read a range
of data which crosses a page boundary. Fix it accordingly by putting an
appropriate loop in instead of...
/* Don't allow a single read to cross a 512-byte block boundary */
if (from + len > ((from | 0x1ff) + 1))
len = ((from | 0x1ff) + 1) - from;
