[U-Boot] am33xx ddr tests

[Ryan]

Hello,

I have 2 chips which are 512mb each connected to the AM33xx processor.

I want to check if the base address is configured for each chip in
u-boot or kernel.

If it is configured in u-boot can anyone point me to where it is configured.

The problem i am facing is i dont if i need to do a
mtest 0x8400000 0xC000000
.
or

mtest 0x8400000 0xA000000.
mtest 0xC000000 0xE000000

Also, is 64MB sufficient for u-boot to function. What is the least
starting address i can give for mtest.

Thanks
