* | ARM: drop "optional" from target select in favor of ARCH_VERSATILEMasahiro Yamada2015-08-12-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit a26cd04920dc ("arch: Make board selection choices optional"), Kconfig could create such an insane .config file that no SoC/board is selected. This is now a real problem for Buildroot, for example. (http://lists.busybox.net/pipermail/buildroot/2015-July/135125.html) This commit drops the "optional" from the ARM target select menu in favor of "Versatile family". Rationale: - Historically, Linux chose versatile_defconfig as the default of ARM defconfig. (arch/arm/Makefile of Linux describes: KBUILD_DEFCONFIG := versatile_defconfig) - It was published by ARM Ltd. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

* | gpio: omap: Drop 'method' parameterTom Rini2015-08-12-38/+35
| | | | | | | | | | | | | | | | | | | | The "method" parameter was part of the original port of the driver from the kernel. At some point this may have been added to allow for future differentiation (as omap1 and omap2 have different GPIO IP blocks, so this wasn't an unreasonable thing to do). At this point however it's just extra overhead, so drop. Signed-off-by: Tom Rini <trini@konsulko.com>

It features a hi6220 SoC which has eight ARM A53 cpu's. This initial port adds support for: - 1) Serial 2) eMMC / SD card 3) USB 4) GPIO It has been tested with Arm Trusted Firmware running u-boot as the BL33 executable. Notes: eMMC has been tested with basic reading of eMMC partition into DDR. I have not tested writing / erasing. Due to lack of clock control it won't be running in the most performant high speed mode. SD card slot has been tested for reading and booting kernels into DDR. It is also currently configured to save the u-boot environment to the SD card. USB has been tested with ASIX networking adapter to tftpboot kernels into DDR. On v2015.07-rc2 dhcp now works, and also USB mass storage are correctly enumerated. GPIO has been tested using gpio toggle GPIO4_1-3 to flash the LEDs.

Hence, we have no source for generating an external snoop requests which appear to be key to the deadlock in DRA72x design. Since we build the same image for DRA74x and DRA72x platforms, lets runtime detect and disable the workaround (in favor of performance) on DRA72x platforms.

* | ARM: Introduce erratum workaround for 801819Nishanth Menon2015-08-12-0/+21

Under certain conditions this can cause the system to deadlock. " Recommended workaround is as follows: Do both of the following: 1) Do not use the write-back no-allocate memory type. 2) Do not issue write-back cacheable stores at any time when the cache is disabled (SCTLR.C=0) and the MMU is enabled (SCTLR.M=1). Because it is implementation defined whether cacheable stores update the cache when the cache is disabled it is not expected that any portable code will execute cacheable stores when the cache is disabled. For implementations of Cortex-A15 configured without the “L2 arbitration register slice” option (typically one or two core systems), you must also do the following: 3) Disable write-streaming in each CPU by setting ACTLR[28:25] = 0b1111 So, we provide an option to disable write streaming on OMAP5 and DRA7. It is a rare condition to occur and may be enabled selectively based on platform acceptance of risk. Applies to: A15 revisions r2p0, r2p1, r2p2, r2p3 or r2p4 and REVIDR[3] is set to 0. Note: certain unicore SoCs *might* not have REVIDR[3] not set, but might not meet the condition for the erratum to occur when they donot have ACP (Accelerator Coherency Port) hooked to ACE (AXI Coherency Extensions). Such SoCs will need the work around handled in the SoC specific manner, since there is no ARM generic manner to detect such configurations.

* | ARM: cache: implement a default weak flush_cache() functionWu, Josh2015-08-12-60/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current many cpu use the same flush_cache() function, which just call the flush_dcache_range(). So implement a weak flush_cache() for all the cpus to use. In original weak flush_cache() in arch/arm/lib/cache.c, there has some code for ARM1136 & ARM926ejs. But in the arch/arm/cpu/arm1136/cpu.c and arch/arm/cpu/arm926ejs/cache.c, there implements a real flush_cache() function as well. That means the original code for ARM1136 & ARM926ejs in weak flush_cache() of arch/arm/lib/cache.c is totally useless. So in this patch remove such code in flush_cache() and only call flush_dcache_range(). Signed-off-by: Josh Wu <josh.wu@atmel.com>

USB powered harddisks do not like this. Currently we power off the USB ports both on a "usb reset" and when booting the kernel, causing the usb-power to bounce off and then back on again. This patch removes the powering off calls, fixing the undesirable power bouncing. Note this requires some special handling for the OTG port: 1) We must skip the external vbus check if we've already enabled our own vbus to avoid false positives 2) If on an usb reset we no longer detect that the id-pin is grounded, turn off vbus as that means an external vbus may be present now Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>

* | arm: socfpga: scan: Factor out IO chain programmingMarek Vasut2015-08-08-71/+42
| | | | | | | | | | | | | | | | Factor out the code which sends JTAG instruction followed by data into separate function to tidy the code up a little. Signed-off-by: Marek Vasut <marex@denx.de> Acked-by: Dinh Nguyen <dinguyen@opensource.altera.com>
* | arm: socfpga: scan: Clean up horrible macrosMarek Vasut2015-08-08-72/+17
| | | | | | | | | | | | | | | | | | | | | | Clean up the horrible macros present in the scan_manager.h . Firstly, the function scan_mgr_io_scan_chain_prg() is static, yet all the macros are used only within it, thus there is no point in having them in the header file. Moreover, the macros are just making the code much less readable, so remove them instead. Signed-off-by: Marek Vasut <marex@denx.de> Acked-by: Dinh Nguyen <dinguyen@opensource.altera.com>
* | arm: socfpga: scan: Introduce generic JTAG accessorMarek Vasut2015-08-08-41/+63
| | | | | | | | | | | | | | | | | | Introduce generic function for accessing the JTAG scan chains in the SCC manager. Make use of this function throughout the SCC manager to replace the ad-hoc writes to registers and make the code less cryptic.

* | arm: socfpga: scan: Clean up scan_chain_engine_is_idle()Marek Vasut2015-08-08-28/+34
| | | | | | | | | | | | | | | | | | | | Rework this function so it's clear that it is only polling for certain bits to be cleared. Add kerneldoc. Fix it's return value to be either 0 on success and -ETIMEDOUT on error and propagate this through the scan manager code.

* | ddr: altera: sequencer: Wrap misc remaining macrosMarek Vasut2015-08-08-0/+17
| | | | | | | | | | | | | | | | | | | | | | Introduce structure socfpga_sdram_misc_config to wrap the remaining misc configuration values in board file. Again, introduce a function, socfpga_get_sdram_misc_config(), which returns this the structure. This is almost the final step toward wrapping the nasty QTS generated macros in board files and reducing the pollution of the namespace.
