-From: Tobias Wolf <dev-NTEO@vplace.de>
-Subject: [v2] MIPS: Fix memory reservation in bootmem_init for certain non-usermem setups
-
-Commit 67a3ba25aa95 ("MIPS: Fix incorrect mem=X@Y handling") introduced a new
-issue for rt288x where "PHYS_OFFSET" is 0x0 but the calculated "ramstart" is
-not. As the prerequisite of custom memory map has been removed, this results
-in the full memory range of 0x0 - 0x8000000 to be marked as reserved for this
-platform.
-
-v2: Correctly compare that usermem is not null.
-
-This patch adds the originally intended prerequisite again.
-
-Signed-off-by: Tobias Wolf <dev-NTEO@vplace.de>
