Subject: New flash chips, AT49F010 and CAT28F512

AT49F010 patch is basically a copy of the existing AT49F020 code, but 
with half the size and the correct ID.
The log was from a write of random data, after the chip already 
contained different random data. I did separate read, erase, write tests 
before but this log seems to show that PREW all work.

CAT28F512 I have successfully probed and read data from, but erase 
fails. Could be because it needs 12v VPP. The CAT28F512 I have is 
soldered on to a NIC. I haven't investigated if VPP is connected at all 
yet. Thought I'd include the patch as-is anyway.

Both patches:
