2016-03-02ARM: at91: avoid defining CONFIG_* symbols in source codeArnd Bergmann1-2/+2
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.

2016-02-25ARM: zynq: Move early printk virtual address to vmalloc areaMichal Simek1-2/+2
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 <michal.simek@xilinx.com> Acked-by: Arnd Bergmann <arnd@arndb.de>
2016-02-09ARM: debug: add support for Palmchip BK-310x UARTMans Rullgard1-0/+11
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.

2016-02-02ARM: imx: enable big endian modeJohannes Berg1-0/+3
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!

2015-12-16ARM: debug-ll: rework footbridge handlingArnd Bergmann1-0/+42
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.

2015-09-21ARM: at91: debug: use DEBUG_UART_PHYSAlexandre Belloni1-14/+4

2014-11-17ARM: shmobile: Add early debugging support using SCIF(A)Geert Uytterhoeven1-0/+52
Add serial port debug macros for the SCIF(A) serial ports. This includes all supported shmobile SoCs, except for EMEV2. The configuration logic (both Kconfig and #ifdef) is more complicated than one would expect, for several reasons: 1. Not all SoCs have the same serial devices, and they're not always at the same addresses. 2. There are two different types: SCIF and SCIFA. Fortunately they can easily be distinguished by physical address. 3. Not all boards use the same serial port for the console. The defaults correspond to the boards that are supported in mainline. If you want to use a different serial port, just change the value of CONFIG_DEBUG_UART_PHYS, and the rest will auto-adapt. 4. debug_ll_io_init() maps the SCIF(A) registers to a fixed virtual address. 0xfdxxxxxx was chosen, as it should lie below VMALLOC_END = 0xff000000, and must not conflict with the 2 MiB reserved region at PCI_IO_VIRT_BASE = 0xfee00000. - On SoCs not using the legacy machine_desc.map_io(), debug_ll_io_init() is called by the ARM core code. - On SoCs using the legacy machine_desc.map_io(), debug_ll_io_init() must be called explicitly. Calls are added for r8a7740, r8a7779, sh7372, and sh73a0. This was derived from the r8a7790 version by Laurent Pinchart.
