CFI command set 0002 (AMD/Fujitsu) work.

[David Vrabel]

Hi,

I'm currently working on cfi_cmdset_0002.c to get erase-suspend-program 
working.  So far I've taken all the chip status checking code and 
refactored it into a single function -- it was all a bit of a mess.

A couple of questions:

1. There's a fair amount of crap related to very broken SST chips (all 
the stuff for retrying commands).  a) This is mess and appears only 
applicable to a very few number of chips; b) I'm not sure it would even 
work if talking to the chip is broken then retrying a few times won't 
guarantee it will work.  I'd suggest removing this stuff from 
cfi_cmdset_0002.c.  Clearly the SST chips aren't compliant even though 
they claim to be.  Thoughts?

2. The "fast programming" feature (unlock bypass) which is currently 
always disabled (due to "code brokeness"). I don't believe this will 
ever work with erase-suspends.  Should the "fast programming" stuff be 
removed?
