If memory size is the only difference between Rev A and B, can we have
device tree default to most used revision and ask bootloader to fix up
memory node for the other revision?  In that case, we only need to
maintain imx28-ts4600.dts then.

If memory size is the only difference between Rev A and B, can we have
device tree default to most used revision and ask bootloader to fix up
memory node for the other revision?  In that case, we only need to
maintain imx28-ts4600.dts then.

If memory size is the only difference between Rev A and B, can we have
device tree default to most used revision and ask bootloader to fix up
memory node for the other revision?  In that case, we only need to
maintain imx28-ts4600.dts then.
