Unfortunately this only takes care of writting operations. Support for read would mean further extensive modifications (introduce some flash_read() function and use it from cp, md, jffs2, ... commands).
Posibly... if addr2info returns structure pointer in question it could also toggle the right gpio line. And it would be nice to have just one addr2info implementation, right Tolunay? ;-)
There is no hook anywhere that would trigger when running a command like
md 0xFF000000 0x100000
which actually might cross "bank" boundaries that require tofggeling of I/O lines. addr2info() is nowhere used in such a szenario. [And it shall not be used, as "md" and friends are supposed to operate on plain memory, exactly as their counterparts in a JTAG debugger would do.]
