* omap3: Use raw SPL by default for mmc1Alexander Graf2016-03-08-2/+0
| | | | | | | | | | | Now that we fall back to the FS code path when we don't find u-boot at the raw sector offset, there is no good reason to not default to raw boot. With this patch, I can successfully boot u-boot from a raw sector offset on beagle-xm. Signed-off-by: Alexander Graf <agraf@suse.de>
* api: Export API structure address as an environment variableStanislav Galabov2016-03-08-0/+1
| | | | | | | | | | This patch makes the U-Boot api export its structure address as an environment variable, so it can be used to directly hint FreeBSD's loader of api's location. The relevant FreeBSD loader change is currently under review at: https://reviews.freebsd.org/D5492 Signed-off-by: Stanislav Galabov <sgalabov@gmail.com>

* pinctrl: uniphier: guard uniphier directory with CONFIG_PINCTRL_UNIPHIERMasahiro Yamada2016-03-09-9/+9
| | | | | | | | | | CONFIG_PINCTRL_UNIPHIER is more suitable than CONFIG_ARCH_UNIPHIER to guard the drivers/pinctrl/uniphier directory. The current CONFIG_PINCTRL_UNIPHIER_CORE is a bit long, so rename it into CONFIG_PINCTRL_UNIPHIER. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* pinctrl: uniphier: set input-enable before pin-muxingMasahiro Yamada2016-03-09-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | While IECTRL is disabled, input signals are pulled-down internally. If pin-muxing is set up first, glitch signals (Low to High transition) might be input to hardware blocks. Bad case scenario: [1] The hardware block is already running before pinctrl is handled. (the reset is de-asserted by default or by a firmware, for example) [2] The pin-muxing is set up. The input signals to hardware block are pulled-down by the chip-internal biasing. [3] The pins are input-enabled. The signals from the board reach the hardware block. Actually, one invalid character is input to the UART blocks for such SoCs as PH1-LD4, PH1-sLD8, where UART devices start to run at the power on reset. To avoid such problems, pins should be input-enabled before muxing.

| * usb: dwc2: disable erroneous overcurrent conditionDinh Nguyen2016-03-05-1/+5
| | | | | | | | | | | | | | | | | | | | | | For the case where an external VBUS is used, we should enable the external VBUS comparator in the driver. This would prevent an unnecessary overcurrent error which would then disable the host port. The overcurrent condition was happening on the SoCFPGA Cyclone5 devkit, thus USB was not working on the devkit. This patch fixes that problem.

| * usb: gadget: composite: Correct recovery path for registerSam Protsenko2016-03-01-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In case when usb_composite_register() failed once (for whatever reason), it will fail further even if all conditions are correct. Example: => fastboot 2 Invalid Controller Index couldn't find an available UDC g_dnl_register: failed!, error: -19 exit not allowed from main input shell. => fastboot 0 g_dnl_register: failed!, error: -22 exit not allowed from main input shell. Despite that 0 is correct index for USB controller, "fastboot 0" command will fail, because "composite" structure wasn't cleared properly on previous fail (on "fastboot 2" command). This patch fixes that erroneous behavior, allowing us to use composite even after previous failure. Signed-off-by: Sam Protsenko <semen.protsenko@linaro.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "fastboot oem format" command reuses "gpt write" command, which in turn requires correct partitions defined in $partitions variable. This patch adds such definition of Android partitions for DRA7XX EVM board. By default $partitions variable contains Linux partition table. In order to prepare Android environment one can run next commands from U-Boot shell: => env set partitions $partitions_android => env save After those operations one can go to fastboot mode and perform "fastboot oem format" to create Android partition table. While at it, enable CONFIG_RANDOM_UUID to spare user from providing UUIDs for each partition manually.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The UniPhier SoC family has not supported ARMv8 yet, but these would cause warnings if they were compiled with a 64bit compiler.

This seems weird because the controller does not need setting in the first place if the size is zero. Also, redefine enum dram_size to represent the DRAM size per 16-bit unit. This makes things simpler because the channel 0 and 1 are connected with 32-bit width DRAM, while the channel 2 is connected with 16-bit width one. I am renaming SIZE_* into DRAM_SZ_* (and also FREQ_* to DRAM_FREQ_* for consistency) while I am here because SIZE_* might be easily mixed-up with the macros in include/linux/sizes.h.
