ST serial flash seems pretty close according to the specs.

Great, 2.6 patch looks promising. Thank you. Can you provide information about
timings for accessing SPI serial flash. As I could see from kernel boot dump on
the maxim.org.za page you seem to be using SPI serial flash for code and data.
Our application has user data on the SPI serial flash and at boot time its
contents is read - it has to be done as fast as possible. Is there some fs you
could recomend for this purpose?
