Hello,
The attached patch adds support for the following Eon SPI flash chips:
EN25Q40, EN25Q80, EN25Q32A/B, EN25Q64, and EN25Q128
I was going to add support for the EN25Q16 as well, but found that it shares
the same ID as the EN25D16 but has different write protection capabilities.
So I added a comment instead.
I do not have real hardware to test with at the moment, so I left the status
as untested.
Datasheets available from Eon @ http://www.eonssi.com/products/products.aspx
