MIPS: BMIPS: Utilize cfe_die() for invalid DTB

2022-07-17T12:53:07Z

If we were not specified a correct DTB, we will not be able to print anything useful with panic() which requires a working console of some sort. Utilize cfe_die() to callback into the CFE default UART and print some useful diagnostics. Signed-off-by: Florian Fainelli Signed-off-by: Thomas Bogendoerfer

MIPS: bmips: Fix compiler warning observed on W=1 build

The function arch_sync_dma_for_cpu_all() was used but was missing a prototype declaration. Signed-off-by: Jim Quinlan Reported-by: kernel test robot Acked-by: Florian Fainelli Signed-off-by: Thomas Bogendoerfer

MIPS: bmips: Remove obsolete DMA mapping support

2022-01-11T10:55:41Z

The code in 'arch/mips/bmips/dma.c' performed DMA mapping for inbound regions. This mapping was and is required for the Broadcom STB PCIe controller HW. This code is removed as the current 'struct device' has a @dma_range_map field which performs the same functionality by processing the "dma-ranges" DT property. Subsequently, ARCH_HAS_PHYS_TO_DMA is now unset since the dma_to_phys() and phys_to_dma() functions are removed.

MIPS: bmips: include for phys_to_dma

mips: bmips: init clocks earlier

device_initcall() is too late for bcm63xx. We need to call of_clk_init() earlier in order to properly boot. Signed-off-by: Álvaro Fernández Rojas Signed-off-by: Thomas Bogendoerfer

MIPS: of: Introduce helper function to get DTB

2021-02-04T12:34:51Z

Selection of the DTB to be used was burried in more or less readable code in head.S. Move this code into a inline helper function and use it. Signed-off-by: Thomas Bogendoerfer Acked-by: Florian Fainelli

MIPS: Remove empty prom_free_prom_memory functions

2021-01-07T16:11:33Z

Most of the prom_free_prom_memory functions are empty. With a new weak prom_free_prom_memory() we can remove all of them. Signed-off-by: Thomas Bogendoerfer Acked-by: Florian Fainelli

MIPS: Use address-of operator on section symbols

2021-01-07T16:10:36Z

When building xway_defconfig with clang: arch/mips/lantiq/prom.c:82:23: error: array comparison always evaluates to true [-Werror,-Wtautological-compare] else if (__dtb_start != __dtb_end) ^ 1 error generated. These are not true arrays, they are linker defined symbols, which are just addresses. Using the address of operator silences the warning and does not change the resulting assembly with either clang/ld.lld or gcc/ld (tested with diff + objdump -Dr). Do the same thing across the entire MIPS subsystem to ensure there are no more warnings around this type of comparison.

dma-direct: rename and cleanup __phys_to_dma

2020-09-11T07:14:43Z

The __phys_to_dma vs phys_to_dma distinction isn't exactly obvious. Try to improve the situation by renaming __phys_to_dma to phys_to_dma_unencryped, and not forcing architectures that want to override phys_to_dma to actually provide __phys_to_dma.

There is no harm in just always clearing the SME encryption bit, while significantly simplifying the interface. Signed-off-by: Christoph Hellwig Reviewed-by: Robin Murphy
