2016-05-26Rename reset to sysresetStephen Warren
The current reset API implements a method to reset the entire system. In the near future, I'd like to introduce code that implements the device tree reset bindings; i.e. the equivalent of the Linux kernel's reset API. This controls resets to individual HW blocks or external chips with reset signals. It doesn't make sense to merge the two APIs into one since they have different semantic purposes. Resolve the naming conflict by renaming the existing reset API to sysreset instead, so the new reset API can be called just reset.

2016-05-26ARM: exynos: Fix build error if SERIAL is disabled in SPLMarek Vasut
If CONFIG_SPL_SERIAL_SUPPORT is not defined in include/configs/exynos5-common.h the following error is produced during the build of the SPL: arch/arm/mach-exynos/built-in.o: In function `do_lowlevel_init': ...u-boot/arch/arm/mach-exynos/lowlevel_init.c:221: undefined reference to `debug_uart_init' Add additional condition to check if SPL build is in progress and in that case check if CONFIG_SPL_SERIAL_SUPPORT is also set before enabling the debug UART.

2016-05-25sunxi: Enable a bunch of commands by default on sunxiHans de Goede
Recently a set of CONFIG_CMD_FOO defines was moved from being defined in config_distro_defaults to Kconfig, and added to all sunxi defconfigs to compensate. Instead of explictly selecting these in all sunxi defconfigs, simply always select these for sunxi boards. This makes the defconfigs simpler and ensures a consistent set of available commands across all sunxi boards. Signed-off-by: Hans de Goede <hdegoede@redhat.com>
2016-05-25arm64: Pine64: update FDT filesAndre Przywara
The originally committed .dts files for the Pine64 were from an early proof-of-concept version and should have never been committed upstream. Replace them with much more mature versions, which also use a different naming scheme. Please note that at this point there is at least one binding which has not been agreed upon, so this is subject to change.

2016-05-25sunxi: Properly announce BOOT_DEVICE_BOARD as "FEL"Bernhard Nortmann

2016-05-25sunxi: Increase SPL header size to 64 bytes to avoid code corruptionSiarhei Siamashka
The current SPL header, created by the 'mksunxiboot' tool, has size 32 bytes. But the code in the boot ROM stores the information about the boot media at the offset 0x28 before passing control to the SPL. For example, when booting from the SD card, the magic number written by the boot ROM is 0. And when booting from the SPI flash, the magic number is 3. NAND and eMMC probably have their own special magic numbers too. Currently the corrupted byte is a part of one of the instructions in the reset vectors table: b reset ldr pc, _undefined_instruction ldr pc, _software_interrupt <- Corruption happens here ldr pc, _prefetch_abort ldr pc, _data_abort ldr pc, _not_used ldr pc, _irq ldr pc, _fiq In practice this does not cause any visible problems, but it's still better to fix it. As a bonus, the reported boot media type can be later used in the 'spl_boot_device' function, but this is out of the scope of this patch.
