good results. It looks like the same applies to the W25x{16,32,64}
products in addition to the W25x{10,20,40,80}. Please update the patch
to include the additional chips.

I just realized that this patch doesn't affect the x16. I really ought
to read the patch more carefully...

Fix erase blocks for Winbond W25X* SPI chips. The Winbond W25X10 and
related chips only have 4k and 64k blocks and only accept erase
commands: 20h, d8h, and c7h.<br>

Tested on a W25x16 flash chip using an NM10 southbridge. Verbose
flashrom -E log attached. Following an erase with a read, the image
produced turns up all 0xFF bytes. The warnings reported seem benign,
and probably have more to do with the NM10 than the flash chip...

<tt>The W25x16 and the W25x16BV use the exact same chip ids but the
W25x16BV supports the already defined erase commands.</tt><br>
