[U-Boot-Users] [PATCH] cfi_flash.c bug fix

[eran.liberty at gmail.com]

this fix a possible bug which occur when the config file defines a flash which is actually smaller than the physical one.
on top of that, if you want to force your flash to appear smaller you can define CONFIG_FORCE_FLASH_BANK_SIZE the a corresponding value.
