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.
