2023-07-11soc: bcm: Move power-domain drivers to the genpd dirUlf Hansson8-1726/+21
To simplify with maintenance let's move the bcm power-domain drivers to the new genpd directory. Going forward, patches are intended to be managed through a separate git tree, according to MAINTAINERS. While moving the drivers, we end up with a directory for bcm63xx that only contains a Kconfig file, which seems a bit silly. Let's therefore also move the Kconfig options into the Kconfig file a directory above, as it allows us to drop the directory too.

2022-11-08ARM: 9263/1: use .arch directives instead of assembler command line flagsNick Desaulniers2-1/+1
Similar to commit a6c30873ee4a ("ARM: 8989/1: use .fpu assembler directives instead of assembler arguments"). GCC and GNU binutils support setting the "sub arch" via -march=, -Wa,-march, target function attribute, and .arch assembler directive. Clang was missing support for -Wa,-march=, but this was implemented in clang-13. The behavior of both GCC and Clang is to prefer -Wa,-march= over -march= for assembler and assembler-with-cpp sources, but Clang will warn about the -march= being unused. clang: warning: argument unused during compilation: '-march=armv6k' [-Wunused-command-line-argument] Since most assembler is non-conditionally assembled with one sub arch (modulo arch/arm/delay-loop.S which conditionally is assembled as armv4 based on CONFIG_ARCH_RPC, and arch/arm/mach-at91/pm-suspend.S which is conditionally assembled as armv7-a based on CONFIG_CPU_V7), prefer the .arch assembler directive. Add a few more instances found in compile testing as found by Arnd and Nathan.

2021-07-01kernel.h: split out panic and oops helpersAndy Shevchenko1-0/+1
kernel.h is being used as a dump for all kinds of stuff for a long time. Here is the attempt to start cleaning it up by splitting out panic and oops helpers. There are several purposes of doing this: - dropping dependency in bug.h - dropping a loop by moving out panic_notifier.h - unload kernel.h from something which has its own domain At the same time convert users tree-wide to use new headers, although for the time being include new header back to kernel.h to avoid twisted indirected includes for existing users.

2020-08-17soc: bcm: brcmstb: biuctrl: Enable Read-ahead cacheFlorian Fainelli1-10/+77
Brahma-B53 and Cortex-A72 CPUs integrated on Broadcom STB SoCs feature a read-ahead cache that performs cache line size adaptation between the bus interface unit and the memory controller. On 32-bit ARM kernels we have to resort to a full featured read-ahead cache driver under arch/arm/mm/cache-b15-rac.c (CONFIG_CACHE_B15_RAC) because there are still cache maintenance operations by set/ways/index that cannot be transparently handled by the ARM Coherency Extension that the read-ahead cache interfaces to. The 64-bit ARM kernel however has long deprecated all of those, so this is simply a one time configuration. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com>
