[LinuxBIOS] Adding support for At29C010A

[Peter Lemenkov]

Hello All!
After a quick look through the specs for At29C020 and At29C040A I
realized that all these chips looks identical. The only difference is
page size - 128 bytes at At29C010A and 256 bytes at 020 and 040
models.

So am I right then suggests that for enabling At20C010A chip I need
only add few lines -

{"At29C010A",    ATMEL_ID,       AT_29C010A,     128, 128,
         probe_jedec,   erase_chip_jedec, write_jedec},

into flashchips.h and only one #define into flash.c?
I don't exactly understand how to find device ID - looks like I need a
small advice :)
