git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC platform changes from Olof Johansson: "New and updated SoC support. Also included are some cleanups where the platform maintainers hadn't separated cleanups from new developent in separate branches. Some of the larger things worth pointing out: - A large set of changes from Alexandre Belloni and Nicolas Ferre preparing at91 platforms for multiplatform and cleaning up quite a bit in the process. - Removal of CSR's "Marco" SoC platform that never made it out to the market. We love seeing these since it means the vendor published support before product was out, which is exactly what we want! New platforms this release are: - Conexant Digicolor (CX92755 SoC) - Hisilicon HiP01 SoC - CSR/sirf Atlas7 SoC - ST STiH418 SoC - Common code changes for Nvidia Tegra132 (64-bit SoC) We're seeing more and more platforms having a harder time labelling changes as cleanups vs new development -- which is a good sign that we've come quite far on the cleanup effort.

2015-01-21ARM: 8274/1: Fix DEBUG_LL for multi-platform kernels (without PL01X)Daniel Thompson1-6/+1
When building a multi_v7_defconfig kernel it is not possible to configure DEBUG_LL to use any serial device except a ARM Primecell PL01X, or more accurately and worse, it is possible to configure a different serial device but KConfig does not honour this request. In fact this also overrides the user selection for some of the single platform kernels, for example I don't think DEBUG_LL can be targeted at ICE or semihosted supervisor for ARCH_VERSATILE. This happens because DEBUG_UART_PL01X is automatically enabled by some architectures and this means user decisions made regarding the DEBUG_LL backend will be overridden. Problem is fixed by removing the automatic enabling of this option.

2015-01-21ARM: 8273/1: Seperate DEBUG_UART_PHYS from DEBUG_LL on EP93XXDaniel Thompson1-1/+2
On EP93XX uncompress.h uses CONFIG_DEBUG_UART_PHYS instead of a hard coded serial port. This means the build breaks when DEBUG_LL (and DEBUG_LL_UART_PL01X) is not enabled. This is fixed by adding a new dependency. Signed-off-by: Daniel Thompson <daniel.thompson@linaro.org> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

We also introduce symbolic names for the registers and flags.

2015-01-21ARM: 8271/1: omap1: Migrate debug_ll macros to use 8250.SDaniel Thompson1-1/+56
The omap1's debug-macro.S is similar to the generic 8250 code. Compared to the 8520 code the omap1 macro automatically determines what UART to use based on breadcrumbs left by the bootloader and automatically copes with the eccentric register layout on OMAP7XX. This patch drops both these features and relies instead on the generic 8250 macros: 1. Dropping support for the bootloader breadcrumbs is identical to the way the migration was handled for OMAP2 (see 808b7e07464d...). 2. Support for OMAP7XX still exists but it must be configured by hand (DEBUG_OMAP7XXUART1/2/3) rather than handled at runtime.

2015-01-21ARM: 8269/1: Remove DEBUG_LL_UART_NONEDaniel Thompson1-9/+0
Only a very small handful of platforms support DEBUG_LL_UART_NONE but it lurks in the menus of every single platform config ready to break the build. This is an especial problem for defconfig/oldconfig since it is often selected by default. This patch solves the problem by removing this option. Any platforms still depending upon this option must be migrated. Signed-off-by: Daniel Thompson <daniel.thompson@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2014-11-17ARM: shmobile: Add early debugging support using SCIF(A)Geert Uytterhoeven1-1/+79
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.

This driver manages CoreSight TMC (Trace Memory Controller) which can act as a link or a sink depending upon its configuration. It can present itself as an ETF (Embedded Trace FIFO) or ETR (Embedded Trace Router). ETF when configured in circular buffer mode acts as a trace collection sink. When configured in HW fifo mode it acts as link. ETR always acts as a sink and can be used to route data to memory allocated in RAM.

2014-11-08coresight: add CoreSight core layer frameworkPratik Patel1-0/+9
CoreSight components are compliant with the ARM CoreSight architecture specification and can be connected in various topologies to suit a particular SoC tracing needs. These trace components can generally be classified as sources, links and sinks. Trace data produced by one or more sources flows through the intermediate links connecting the source to the currently selected sink. The CoreSight framework provides an interface for the CoreSight trace drivers to register themselves with. It's intended to build up a topological view of the CoreSight components and configure the correct serie of components on user input via sysfs. For eg., when enabling a source, the framework builds up a path consisting of all the components connecting the source to the currently selected sink(s) and enables all of them. The framework also supports switching between available sinks and provides status information to user space applications through the debugfs interface.

2014-10-20ARM: pxa: fix hang on startup with DEBUG_LLRobert Jarzmik1-1/+1
The commit 2111667b4677 ("ARM: pxa: call debug_ll_io_init for earlyprintk") triggers in the current kernel the attached backtrace on PXA/tosa early in the boot time when DEBUG_LL is enabled. It is due to overlap between uart virtual memory defined in DEBUG_UART_VIRT and mapped by debug_ll_io_init() and peripheral bus mapped by pxa_map_io at the same address, 0xf2100000. As hinted by Arnd, map early virtual memory for low level debug on address 0xf6200000, even if that means 2 virtual mappings will give access to the pxa internal UARTs (FFUART, BTUART, STUART, ...). ------------[ cut here ]------------ kernel BUG at /home/lumag/linux/mm/vmalloc.c:1143!
