2016-06-12arm: Allow skipping of low-level init with I-cache onSimon Glass
At present CONFIG_SKIP_LOWLEVEL_INIT prevents U-Boot from calling lowlevel_init(). This means that the instruction cache is not enabled and the board runs very slowly.

2016-06-12x86: Probe pinctrl driver in cpu_init_r()Bin Meng
At present pinctrl driver gets probed in ich6_gpio driver's probe routine, which has two issues: - Pin's PADs only gets configured when GPIO driver is probed, which is not done by default. This leaves the board in a partially functional state as we must initialize PADs correctly to get perepherals fully working. - The probe routine of pinctrl driver is called multiple times, as normally there are multiple GPIO controllers. It should really be called just once. Move the call to syscon_get_by_driver_data() from ich6_gpio driver to cpu_init_r().

2016-06-12x86: baytrail: Configure card detect pin of the SD controllerBin Meng
As of today, the latest version FSP (gold4) for BayTrail misses the PAD configuration of the SD controller's Card Detect signal. The default PAD value for the CD pin sets the pin to work in GPIO mode, which causes card detect status cannot be reflected by the Present State register in the SD controller (bit 16 & bit 18 are always zero). Add a configuration for this pin in the pinctrl node. Note I've checked the PAD configuration for all the pins in all the 3 controllers (eMMC/SDIO/SD). Only this SDMMC3_CD_B pin does not get initialized to correct mode by FSP. With fsp,emmc-boot-mode set to 2 (eMMC 4.1), eMMC pins are initialized to func 1, but if we set fsp,emmc-boot-mode to 1 (auto), those pins are initialized to func 3 which is correct according to datasheet.

2016-06-12x86: baytrail: Change fsp, emmc-boot-mode to "auto"Bin Meng
At present all BayTrail boards configure fsp,emmc-boot-mode to 2, which means "eMMC 4.1" per FSP documentation. However, eMMC 4.1 only shows up on some early stepping silicon of BayTrail SoC. Newer stepping SoC integrates an eMMC 4.5 controller. Intel FSP provides a config option fsp,emmc-boot-mode which tells FSP which eMMC controller it initializes. Instead of hardcoded to 2, now we change it to 1 which means "auto". With this change, MinnowMax board (with a D0 stepping BayTrail SoC) can see the eMMC 4.5 controller at PCI address 00.17.00 via U-Boot 'pci' command.

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).

2016-06-06arm/arm64: implement a boot header capabilityAndre Przywara
Some SPL loaders (like Allwinner's boot0, and Broadcom's boot0) require a header before the actual U-Boot binary to both check its validity and to find other data to load. Sometimes this header may only be a few bytes of information, and sometimes this might simply be space that needs to be reserved for a post-processing tool. Introduce a config option to allow assembler preprocessor commands to be inserted into the code at the appropriate location; typical assembler preprocessor commands might be: .space 1000 .word 0x12345678 Signed-off-by: Andre Przywara <andre.przywara@arm.com> Signed-off-by: Steve Rae <srae@broadcom.com> Commit Notes: Please note that the current code: start.S (arm64) and vectors.S (arm) already jumps over some portion of data already, so this option basically just increases the size of this region (and the resulting binary). For use with Allwinner's boot0 blob there is a tool called boot0img[1], which fills the header to allow booting A64 based boards. For the Pine64 we need a 1536 byte header (including the branch instruction) at the moment, so we add this to the defconfig.
