[flashrom] [PATCH] Add support for SST39LF010, SST39LF020 and SST39LF040

[Hatim Kanchwala]

Hello,

I am learning about parallel flash chips. My approach is to go through datasheets of chips supported by flashrom and then add support for other member chips of the family. AFAIK, following three chips differ from VF variants only in voltage range. I was able to find very little about parallel flash on the internet, so I will continue with this approach (what do you guys think? :P). If you have any resources or any particular parallel chip family in mind, please let me know (via mail or IRC ;)).

Thanks! :)
