MLK-20051-2 imx8mq_arm2: Split DDR to two banks for iMX8MQ DDR4 ARM2
Because the iMX8MQ DDR4 ARM2 has 4GB DDR. To fit new MMU settings, we split
it to two banks. The first bank has 3GB DDR, reach to 4GB memory map.
The second bank has 1GB DDR, is beyond 4GB memory map.
Notice: there is no OPTEE for ARM2 board. The trust zone setting in OPTEE
for iMX8MQ EVK is not match with DDR size on ARM2 board. So ARM2 Only can
work without OPTEE.
