Can you change the naming to "chunk"? "page" and "block" have meanings
which do not match the code very well.

I think I saw a data sheet which stated that you may not read
arbitrarily large chunks of the chip. Although the current ICH SPI code
is not matching the design of the parallel flash chip drivers, your
change will effectively change the chunk size for reads.

There are some other architectural changes which look good at first, but
they are unneeded. Look at ich_spi_read_block and tell me why you want
block_size as a parameter. The block size should be stored in struct
flashchip and not be passed around separately.
