we are trying to extend flash size ,

the driver we use is cfiscs.c
what is the easiest method to do it please?
we tried to manipulate cfi INIT chipsize ,and change some functions of
the driver (like read , write , erase , lock , unlock , check status)
but without luck so far
even with jtag, we cant erase the sectors of the new flash, if we
change BR0 and OR0 flash chip select to match the new window
(but in the BKM we manage to issue erase , unlock and such)
any help would be awesome
thanks in advance
