mips: bmips: fix syscon-reboot nodes

2021-05-14T08:50:03+00:00

[ Upstream commit cde58b861a1d365568588adda59d42351c0c4ad3 ]

Commit a23c4134955e added the clock controller nodes, incorrectly changing the
syscon-reboot nodes addresses.

MIPS: compressed: fix build with enabled UBSAN

2021-03-04T11:15:21+00:00

commit fc4cac4cfc437659ce445c3c47b807e1cc625b66 upstream.

Commit 1e35918ad9d1 ("MIPS: Enable Undefined Behavior Sanitizer
UBSAN") added a possibility to build the entire kernel with UBSAN
instrumentation for MIPS, with the exception for VDSO.
However, self-extracting head wasn't been added to exceptions, so
this occurs:

mips-alpine-linux-musl-ld: arch/mips/boot/compressed/decompress.o:
in function `FSE_buildDTable_wksp':
decompress.c:(.text.FSE_buildDTable_wksp+0x278): undefined reference
to `__ubsan_handle_shift_out_of_bounds'
mips-alpine-linux-musl-ld: decompress.c:(.text.FSE_buildDTable_wksp+0x2a8):
undefined reference to `__ubsan_handle_shift_out_of_bounds'
mips-alpine-linux-musl-ld: decompress.c:(.text.FSE_buildDTable_wksp+0x2c4):

mips-alpine-linux-musl-ld: arch/mips/boot/compressed/decompress.o:
decompress.c:(.text.FSE_buildDTable_raw+0x9c): more undefined references
to `__ubsan_handle_shift_out_of_bounds' follow

Add UBSAN_SANITIZE := n to mips/boot/compressed/Makefile to exclude
it from instrumentation scope and fix this issue.

MIPS: boot: Fix unaligned access with CONFIG_MIPS_RAW_APPENDED_DTB

2020-12-28T22:26:16+00:00

The compressed payload is not necesarily 4-byte aligned, at least when
compiling with Clang. In that case, the 4-byte value appended to the
compressed payload that corresponds to the uncompressed kernel image
size must be read using get_unaligned_le32().

This fixes Clang-built kernels not booting on MIPS (tested on a Ingenic
JZ4770 board).

MIPS: DTS: img: Fix schema warnings for pwm-leds

2020-12-05T10:24:29+00:00

The node names for devices using the pwm-leds driver follow a certain
naming scheme (now).  Parent node name is not enforced, but recommended
by DT project.

MIPS: Enable GCOV

2020-12-04T12:00:53+00:00

Enable gcov profiling of the entire kernel on mips. Required changes
include disabling profiling for:

* arch/kernel/boot/compressed: not linked to main kernel.

Lightly tested on Loongson 3A3000 an 3A4000, seems to work as expected.

without "GCOV_PROFILE := n" in compressed Makefile,
build errors as follows:
...
ld: arch/mips/boot/compressed/string.o:(.data+0x88):
 undefined reference to `__gcov_merge_add'
ld: arch/mips/boot/compressed/string.o:
