ARM: brcmstb: Add earlyprintk support using run-time checks

2016-08-08T18:14:09Z

The SUN_TOP_CTRL_FAMILY_ID register is at a fixed absolute address for all of our supported chips, so utilize its value to determine what the UARTA base address should be based on the value we read. Since the code is called both during decompressor when the MMU is off, and after the MMU has been turned on in the kernel, and we want to do the lookup only once, we use the same technique as tegra.S and have a shared storage location between the decompressor and the kernel.

ARM: clps711x: Reduce static map size

2016-07-06T15:38:52Z

Last CLPS711X CPU register is PLLR has 0xa5a8 address, so we can reduce the map to 48k and align the end of the static at VMALLOC_START. Signed-off-by: Alexander Shiyan Signed-off-by: Arnd Bergmann

ARM: EXYNOS: Fix UART address selection for DEBUG_LL

2016-06-22T06:20:43Z

The Exynos542x SoCs using A15+A7 can boot to A15 or A7. If it boots using A7 (like on Odroid XU family boards), it can't choose right UART physical address only the part number of CP15. Fix the detection logic by checking the Cluster ID additionally. Signed-off-by: Joonyoung Shim Tested-by: Marek Szyprowski [k.kozlowski: Extend commit message] Signed-off-by: Krzysztof Kozlowski

ARM: EXYNOS: Fixup debug macros for big-endian

2016-06-21T11:08:09Z

The exynos low-level debug macros need to be fixed if the system is being built big endian. Add the necessary endian swaps for accessing the registers to get output working again Signed-off-by: Ben Dooks Signed-off-by: Krzysztof Kozlowski

ARM: at91: debug: use DEBUG_UART_VIRT

2016-06-10T15:08:56Z

AT91 still uses an offset (0x0100 0000) from the physical address to map the debug UART. This is unfortunate as for some platforms (sama5d3 and earlier), it ends up in the PCI zone and PCI is enabled in multi_v7. Switch to DEBUG_UART_VIRT to solve that. Tested on sama5d3 and 9g20.

ARM: at91: avoid defining CONFIG_* symbols in source code

2016-03-02T16:31:08Z

In an invalid randconfig build (fixed by another patch), I ran across this warning: arch/arm/include/debug/at91.S:18:0: error: "CONFIG_DEBUG_UART_VIRT" redefined [-Werror] #define CONFIG_DEBUG_UART_VIRT AT91_IO_P2V(CONFIG_DEBUG_UART_PHYS) As Russell pointed out, we should never #define a macro starting with CONFIG_ in a source file, as that is rather confusing. This renames the macro to avoid the symbol clash. Signed-off-by: Arnd Bergmann Suggested-by: Russell King Acked-by: Alexandre Belloni Acked-by: Nicolas Ferre

Merge "ARM: Xilinx Zynq patches for v4.6" from Michal Simek: - SLCR early init - Fix L2 cache data corruption - Fix early printk uart setting * tag 'zynq-soc-for-4.6' of https://github.com/Xilinx/linux-xlnx: ARM: zynq: Move early printk virtual address to vmalloc area ARM: zynq: address L2 cache data corruption ARM: zynq: initialize slcr mapping earlier

ARM: zynq: Move early printk virtual address to vmalloc area

2016-02-25T13:06:03Z

The patch "ARM: 8432/1: move VMALLOC_END from 0xff000000 to 0xff800000" (sha1: 6ff0966052c46efb53980b8a1add2e7b49c9f560) has moved also start of VMALLOC area because size didn't change. That's why origin location of vmalloc was vmalloc : 0xf0000000 - 0xff000000 ( 240 MB) and now is vmalloc : 0xf0800000 - 0xff800000 ( 240 MB) That's why uart virtual addresses need to be changed to reflect this new memory setup. Starting address should be vmalloc start address. Signed-off-by: Michal Simek Acked-by: Arnd Bergmann
