MIPS: generic/yamon-dt: fix uninitialized variable error

2021-11-25T08:48:36+00:00

[ Upstream commit 255e51da15baed47531beefd02f222e4dc01f1c1 ] In the case where fw_getenv returns an error when fetching values for ememsizea and memsize then variable phys_memsize is not assigned a variable and will be uninitialized on a zero check of phys_memsize. Fix this by initializing phys_memsize to zero. Cleans up cppcheck error: arch/mips/generic/yamon-dt.c:100:7: error: Uninitialized variable: phys_memsize [uninitvar] Fixes: f41d2430bbd6 ("MIPS: generic/yamon-dt: Support > 256MB of RAM") Signed-off-by: Colin Ian King Signed-off-by: Thomas Bogendoerfer Signed-off-by: Sasha Levin

MIPS: ingenic: Unconditionally enable clock of CPU #0

2021-08-29T11:31:02+00:00

Make sure that the PLL that feeds the CPU won't be stopped while the kernel is running. This fixes a problem on JZ4760 (and probably others) where under very specific conditions, the main PLL would be turned OFF when the kernel was shutting down, causing the shutdown process to fail.

MIPS: generic: Allow generating FIT image for Marduk board

2021-08-12T14:01:49+00:00

Marduk is based on IMG pistachio SoC. The platform is using MIPS UHI booting protocol and does have a proper devicetree implement, thus it could be a part of generic kernel. Signed-off-by: Jiaxun Yang Signed-off-by: Thomas Bogendoerfer

MIPS: generic: Update node names to avoid unit addresses

2021-04-12T14:48:35+00:00

With the latest mkimage from U-Boot 2021.04, the generic defconfigs no longer build, failing with: /usr/bin/mkimage: verify_header failed for FIT Image support with exit code 1 This is expected after the linked U-Boot commits because '@' is forbidden in the node names due to the way that libfdt treats nodes with the same prefix but different unit addresses. Switch the '@' in the node name to '-'. Drop the unit addresses from the hash and kernel child nodes because there is only one node so they do not need to have a number to differentiate them.
