[U-Boot-Users] parallel FLASH

just wondering... how did you connect the adress lines?
for 16-Bit Mode you need to connect down to A30, for 32-Bit Mode you need to
connect down to A29

either you will have weird adressing during programming or you have to shift
all adress lines

I have a MPC860T board which can have one or two FLASH chips on it. When
one FLASH chip is on it it is used in 16bit mode, if two FLASH chips are
present it is used in 32 bit mode ( 2 * 16bit FLASH chips in parallel ).
The initial chip select is set by a hardware jumper with the reset-word.
