* ARM: 9234/1: stacktrace: Avoid duplicate saving of exception PC valueLi Huafei2022-10-213-14/+37

However, the actual CMDLINE cofiguration option does not depend on ATAGS, and the code that handles this is not specific to ATAGS (see drivers/of/fdt.c:early_init_dt_scan_chosen()). Hence users who desire to override the kernel command line on arm32 must enable support for ATAGS, even on a pure-DT system. Other architectures (arm64, loongarch, microblaze, nios2, powerpc, and riscv) do not impose such a restriction. Hence drop the dependency on ATAGS.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A recent change affecting the behaviour of phys_to_dma() to actually require the device tree ranges to work unmasked a bug in the Integrator DMA ranges. The PL110 uses the CMA allocator to obtain coherent allocations from a dedicated 1MB video memory, leading to the following call chain: drm_gem_cma_create() dma_alloc_attrs() dma_alloc_from_dev_coherent() __dma_alloc_from_coherent() dma_get_device_base() phys_to_dma() translate_phys_to_dma() phys_to_dma() by way of translate_phys_to_dma() will nowadays not provide 1:1 mappings unless the ranges are properly defined in the device tree and reflected into the dev->dma_range_map. There is a bug in the device trees because the DMA ranges are incorrectly specified, and the patch uncovers this bug. Solution: - Fix the LB (logic bus) ranges to be 1-to-1 like they should have always been. - Provide a 1:1 dma-ranges attribute to the PL110. - Mark the PL110 display controller as DMA coherent. This makes the DMA ranges work right and makes the PL110 framebuffer work again.

| * | | ARM: at91: pm: fix DDR recalibration when resuming from backup and self-refreshClaudiu Beznea2022-08-311-4/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On SAMA7G5, when resuming from backup and self-refresh, the bootloader performs DDR PHY recalibration by restoring the value of ZQ0SR0 (stored in RAM by Linux before going to backup and self-refresh). It has been discovered that the current procedure doesn't work for all possible values that might go to ZQ0SR0 due to hardware bug. The workaround to this is to avoid storing some values in ZQ0SR0. Thus Linux will read the ZQ0SR0 register and cache its value in RAM after processing it (using modified_gray_code array). The bootloader will restore the processed value.

Debugging and investigating it proved that disabling AC DLL introduce glitches in RAM controllers which leads to unexpected behavior. This is confirmed as a hardware bug. DLL bypass disables 3 DLLs: 2 DX DLLs and AC DLL. Thus, keep only DX DLLs disabled. This introduce 6mA extra current consumption on VDDCORE when switching to any ULP mode or standby mode but the self-refresh procedure still works.
