4 | Subject: [PATCH 21/56] Revert "i.MX28: Enable additional DRAM address bits" | ||
5 | |||
6 | This reverts commit 69d26d09de1cb93e0a09ca71d9f0d41a66f0756a. | ||
7 | |||
8 | Apparently, this commit got mainline only because of out-of-tree | ||
9 | port and causes breakage on board that is mainline. Revert. | ||
10 | |||
11 | Reason: | ||
12 | * The OOT board has 512MB of DRAM, enabling this additional address | ||
13 | line enabled it to work fine with 512MB of RAM. | ||
14 | * Every mainline port has max. 256MB of DRAM, therefore this revert | ||
15 | has no impact on any mainline port | ||
16 | * Though this caused a problem with new M28 board with 256MB of DRAM | ||
17 | where the chips are wired differently. The patch-to-be-reverted | ||
18 | caused the DRAM to behave like this: | ||
19 | |||
20 | [128MB chunk #1][128MB chunk #1 again][128MB chunk #2][128MB chunk #2 again] | ||
21 | |||
22 | Therefore to retain the current one-memory-init-rules-them-all situation, | ||
23 | revert this patch until another board emerges and will actually be pushed | ||
24 | mainline that needs different setup. | ||
