ARM: debug-ll: rework footbridge handling

2015-12-15T22:43:29Z

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

2015-09-21T14:31:15Z

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

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

ARM: zynq: Fix earlyprintk in big endian mode

2015-07-22T07:37:58Z

earlyprintk messages are not appearing on the terminal emulator during a big endian kernel boot. In BE mode sending full words to UART will result in unprintable characters as they are byte swapped versions of printable ones. So send only bytes.
