2016-06-19clk: convert API to match reset/mailbox styleStephen Warren
The following changes are made to the clock API: * The concept of "clocks" and "peripheral clocks" are unified; each clock provider now implements a single set of clocks. This provides a simpler conceptual interface to clients, and better aligns with device tree clock bindings. * Clocks are now identified with a single "struct clk", rather than requiring clients to store the clock provider device and clock identity values separately. For simple clock consumers, this isolates clients from internal details of the clock API. * clk.h is split so it only contains the client/consumer API, whereas clk-uclass.h contains the provider API. This aligns with the recently added reset and mailbox APIs. * clk_ops .of_xlate(), .request(), and .free() are added so providers can customize these operations if needed. This also aligns with the recently added reset and mailbox APIs. * clk_disable() is added. * All users of the current clock APIs are updated. * Sandbox clock tests are updated to exercise clock lookup via DT, and clock enable/disable. * rkclk_get_clk() is removed and replaced with standard APIs. Buildman shows no clock-related errors for any board for which buildman can download a toolchain. test/py passes for sandbox (which invokes the dm clk test amongst others).

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.
