flash unlock on VPB

[stiger]

hello,

i'm using VPB + kernel 2.6.9
but i found the flash cannot write, it should be unlocked first.

if not use root filesystem in flash, I can use flash_unlock to unlock the
flash.
but if burn root filesystem into flash, i have to change the kernel code.

i add these code at driver/mtd/mtdpart.c->add_mtd_partitions()

        if((slave->mtd.flags & MTD_WRITEABLE) && slave->mtd.unlock ){
            slave->mtd.unlock(&(slave->mtd), 0, slave->mtd.size );
        }

now, it works.
but i think it's a stupid way to do this.
is there any other way to do this ?
