2016-06-10board: ls2080a: Add "mcinitcmd" env for MC & DPL deploymentPratiyush Mohan Srivastava
Environment variable mcinitcmd is defined to initiate MC and DPL deployment from the location where it is stored (NOR, NAND, SD, SATA, USB) during booting. If this variable is not defined then macro MC_BOOT_ENV_VAR will be null and MC will not be booted and DPL will not be applied during U-boot booting.

2016-06-10sunxi: Move the SPL stack top to 0x1A000 on Allwinner A64/A80Siarhei Siamashka
Since the SRAM C corruption issue is now resolved on Allwinner A64, it is possible to move the stack top to the address 0x1A000 on both A64 and A80. The boot ROM can load SPL binaries with up to 32 KiB size on A64 (the 24 KiB SPL size limitation only affects A10/A20), and this patch also ensures the availability of 8 KiB stack.

2016-06-10sunxi: Downclock AHB1 to 100MHz on Allwinner A64Siarhei Siamashka
Currently the AHB1 clock speed is configured as 200MHz by the SPL, but this causes a subtle and hard to reproduce data corruption in SRAM C (for example, this can't be easily detected with a trivial memset/memcmp test). For what it's worth, the Allwinner's BSP configures AHB1 as 200MHz, as can be verified by running the devmem2 tool in the system running the Allwinner's kernel 3.10.x: 0x1C20028: PLL_PERIPH0_CTRL_REG = 0x90041811 0x1C20054: AHB1_APB1_CFG_REG = 0x3180 0x1C20058: APB2_CFG_REG = 0x1000000 0x1C2005C: AHB2_CFG_REG = 0x1 However the FEL mode uses more conservative settings (100MHz for AHB1): 0x1C20028: PLL_PERIPH0_CTRL_REG = 0x90041811 0x1C20054: AHB1_APB1_CFG_REG = 0x3190 0x1C20058: APB2_CFG_REG = 0x1000000 0x1C2005C: AHB2_CFG_REG = 0x0 It is yet to be confirmed whether faster AHB1/AHB2 clock settings can be used safely if we initialize the AXP803 PMIC instead of using reset defaults. But in order to resolve the data corruption problem right now, it's best to downclock AHB1 to a safe level. Note that this issue only affects the SPL, which is not fully supported on Allwinner A64 yet and it should not affect the boot0 usage (unless somebody can confirm SRAM C corruption with the boot0 too).

2016-06-10spi: pic32_spi: add SPI master driver for PIC32 SoC.Purna Chandra Mandal
This driver implements SPI protocol in master mode to communicate with the SPI device connected on SPI bus. It handles /CS explicitly by controlling respective pin as gpio ('cs-gpios' property in dt node) and uses PIO mode for SPI transaction. It is configurable based on driver-model only.

2016-06-09ARM: uniphier: insert dsb barrier to ensure visibility of storeMasahiro Yamada
I noticed secondary CPUs sometimes fail to wake up, and the root cause is that the sev instruction wakes up slave CPUs before the preceding the register write is observed by them. The read-back of the accessed register does not guarantee the order.
