Enable testing kernel. Fix compile errors by using new kernel APIs. Fix fuzz by manually editing patches to ensure the code goes in the right place. For 721-NET-no-auto-carrier-off-support.patch, revert upstream commit a307593a6 to keep the OpenWrt ralink driver operational. Add mt7621-pci-phy patch to select REGMAP_MMIO as discussed in PR #3693 and #3952. Run automatic quilt refresh on the rest. Signed-off-by: Ilya Lipnitskiy <ilya.lipnitskiy@gmail.com>

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.
