Revert "i.MX28: Enable additional DRAM address bits"
This reverts commit 69d26d09de1cb93e0a09ca71d9f0d41a66f0756a.
Apparently, this commit got mainline only because of out-of-tree
port and causes breakage on board that is mainline. Revert.
Reason:
* The OOT board has 512MB of DRAM, enabling this additional address
line enabled it to work fine with 512MB of RAM.
* Every mainline port has max. 256MB of DRAM, therefore this revert
has no impact on any mainline port
* Though this caused a problem with new M28 board with 256MB of DRAM
where the chips are wired differently. The patch-to-be-reverted
caused the DRAM to behave like this:
[128MB chunk #1][128MB chunk #1 again][128MB chunk #2][128MB chunk #2 again]
Therefore to retain the current one-memory-init-rules-them-all situation,
revert this patch until another board emerges and will actually be pushed
mainline that needs different setup.
