Do not order a lot of SST chips, they are much more difficult to support
with the current flashrom architecture. You could order one and check if
they support the RDID instruction (data sheet is silent about RDID), but
I have no idea if they do.
EON chips have other pitfalls, but they should theoretically still be
easier to support.
