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

2016-03-02T16:31:08+00:00

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

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

2016-02-25T13:06:03+00:00

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

ARM: debug: add support for Palmchip BK-310x UART

2016-02-08T21:52:34+00:00

Some SoCs use a Palmchip BK-310x UART which is mostly 16550 compatible but with a different register layout. While this UART has previously only been supported in MIPS based chips (Alchemy, Ralink), the ARM based SMP87xx series from Sigma Designs also uses it. This patch allows the debug console to work with this type of UART.

ARM: imx: enable big endian mode

2016-02-02T05:31:19+00:00

Enable ARM big-endian mode on mach-imx. This requires adding some byte swapping in the debug functions (which otherwise hang forever) and of course the secondary core bringup. Tested (on top of 4.4) on i.MX6 HummingBoard quad-core (IMX6Q). The patch is pretty much as suggested by Arnd Bergmann, thanks! Signed-off-by: Johannes Berg Signed-off-by: Shawn Guo

ARM: debug-ll: rework footbridge handling

2015-12-15T22:43:29+00:00

Footbridge has two debug ports that are handled a bit differently: The 8250 port uses the normal debug/8250.S implementation that is shared with a lot of other platforms, but it relies on the DEBUG_UART_8250 option to be turned on automatically instead of being selected by DEBUG_FOOTBRIDGE_COM1 as we do for most other platforms. I'm changing this to use a 'select' and change the dependency to the debug symbol rather than the platform symbol for consistency. The DC21285 UART has a separate top-level option, and relies on the traditional include/mach/debug-macro.S method. With the s3c64xx multiplatform series queued up for 4.5, it is now the last one that does this, so by moving this file to include/debug/dc21285.S, we can get all platforms to do things the same way.

ARM: at91: debug: use DEBUG_UART_PHYS

2015-09-21T14:31:15+00:00

Instead of having to add a new configuration option each time support for new SoC is added, use CONFIG_DEBUG_UART_PHYS. For now, CONFIG_DEBUG_UART_VIRT is automatically computed. Signed-off-by: Alexandre Belloni Signed-off-by: Nicolas Ferre

2015-08-18T20:10:05+00:00

The i.MX SoC changes for 4.3: - Add i.MX6 Ultralite SoC support, which is the newest addition to i.MX6 family. It integrates a single Cortex-A7 core and a power management module that reduces the complexity of external power supply and simplifies power sequencing. - Change SNVS RTC driver to use syscon interface for register access, and add SNVS power key driver support. - Add a second clock for mxc rtc driver, and support device tree probe for the driver. - Add FEC MAC reference clock and phy fixup initialization for i.MX6UL platform. * tag 'imx-soc-4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux: rtc: snvs: select option REGMAP_MMIO ARM: imx6ul: add fec MAC refrence clock and phy fixup init ARM: imx6ul: add fec bits to GPR syscon definition rtc: mxc: add support of device tree dt-binding: document the binding for mxc rtc rtc: mxc: use a second rtc clock input: snvs_pwrkey: use "wakeup-source" as deivce tree property name Document: devicetree: input: imx: i.mx snvs power device tree bindings input: keyboard: imx: add snvs power key driver Document: dt: fsl: snvs: change support syscon rtc: snvs: use syscon to access register ARM: imx: add low-level debug support for i.mx6ul ARM: imx: add i.mx6ul msl support Signed-off-by: Olof Johansson
