[U-Boot] Reading from NAND

[D Kesselring]

After some experimenting the only issue that I have now is trying to
do an itest on a non-aligned byte. I get an alignment exception if I
test a non-word aligned bype. Is there a way to do a bitwise AND so
that I can read a word and mask out the byte that I am interested in?
Also does the shell support adding values like "itest *(${base} +
${offset}) == 0x01"?

Thanks,
David
