* | colibri-vf: Disable pull-up configuration in GPIO pin muxBhuvanchandra DV2016-03-02-1/+1
| | | | | | | | | | | | | | | | | | | | | | During very early boot-ROM execution the pinmux configuration isi in Hi-Z state. If pull-up is enabled on GPIO pad's there will be a short period of toggle from high to low on the IO when GPIO is set low during boot. To avoid this glitch, disable pull-up configuration in GPIO pinmux. Signed-off-by: Bhuvanchandra DV <bhuvanchandra.dv@toradex.com>

* | arm: dra7xx: Define Android partition tableSam Protsenko2016-02-29-1/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "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.

| * | ARM: uniphier: fix warnings reported by aarch64 compilerMasahiro Yamada2016-03-01-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The UniPhier SoC family has not supported ARMv8 yet, but these would cause warnings if they were compiled with a 64bit compiler. Before adding the ARMv8 support really, fix them now. Because UniPhier SoCs do not support Large Physical Address Extension, casting "phys_addr_t" into "unsigned long" would carry the address as is.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before adding ARMv8 support, this commit refactors the directory structure. Move ARMv7 specific files to arch/arm/mach-uniphier/arm32 to avoid a mess by mixture of ARMv7 and ARMv8 code. Also move the "select CPU_V7" to the lower-level menu because we will have to select ARM64 instead of CPU_V7 for ARMv8 SoCs. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The chains of "depends on <SoC_name>" in the current Kconfig is clumsy. The idea here is to allow users to choose a SoC group first (SoC group consists of some SoCs that can coexist in one binary). Then, allow to enable/disable each SoC support in the selected SoC group. This makes the Kconfig menu clearer. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

| | | | | | | | | | | | | | | | | | | | | | | | These settings were used only for the PH1-sLD3 and older SoCs. The PH1-LD4 and newer one just ignore them because their DDR-PHY take care of such timing parameters instead. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
| * | ARM: uniphier: refactor UMC init code for ProXstream2Masahiro Yamada2016-02-29-45/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, a dummy value is defined for the UMC_SPCCTLA register when the DRAM size is zero. 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.

It might be a bit advanced for some users. To be user-friendly, this commit adds a useful command to update the images; just put SPL and U-Boot proper into the public directory of the TFTP server and execute "run emmcupdate" from the command line.
