The flash part is a CFI-compatible MBM29DL32XBD by Fujitsu. The flash
driver (drivers/char/flash.c and cfi_flash.c) is by DENX Software
Engineering (Wolfgang Denk, wd@denx.de).

I'm not sure what Vpen is. But if you mean anything like the Write Enable
pin of the flash part, it ought to be. The hardware has been verified
'coz we used to run a different OS (OS9000) and flash filesystem (FTL) on
it, and the same flash could do read/write with no problem.
