2017-08-28mmc: sunxi: Support new modeMaxime Ripard
Almost all of the newer Allwinner SoCs have a new operating mode for the eMMC clocks that needs to be enabled in both the clock and the MMC controller. Details about that mode are sparse, and the name itself (new mode vs old mode) doesn't give much details, but it seems that the it changes the sampling of the MMC clock. One side effect is also that it divides the parent clock rate by 2. Add support for it through a Kconfig option.

Also replace BMODE_UART with BMODE_RESERVED, which is more appropriate. Commit 96aac843b68d ("imx: Use IMX6_BMODE_* macros instead of numericals") added macros for boot modes, in the process the reserved boot mode got named BMODE_UART. We use the reserved boot mode in the bmode command to let the boot ROM enter serial downloader recovery mode. But this is only a side effect, the actual boot mode is reserved...

2017-08-13ARM: OMAP5: Enable support for AVS0 for OMAP5 production devicesNishanth Menon
OMAP5432 did go into production with AVS class0 registers which were mutually exclusive from AVS Class 1.5 registers. Most OMAP5-uEVM boards use the pre-production Class1.5 which has production efuse registers set to 0. However on production devices, these are set to valid data. scale_vcore logic is already smart enough to detect this and use the "Nominal voltage" on devices that do not have efuse registers populated. On a test production device populated as follows: MPU OPP_NOM: => md.l 0x04A0021C4 1 4a0021c4: 03a003e9 .... (0x3e9 = 1.01v) vs nom voltage of 1.06v MPU OPP_HIGH: => md.l 0x04A0021C8 1 4a0021c8: 03400485 ..@. MM OPP_NOM: => md.l 0x04A0021A4 1 4a0021a4: 038003d4 .... (0x3d4 = 980mV) vs nom voltage of 1.025v MM OPP_OD: => md.l 0x04A0021A8 1 4a0021a8: 03600403 ..`. CORE OPP_NOM: => md.l 0x04A0021D8 1 4a0021d8: 000003cf .... (0x3cf = 975mV) vs nom voltage of 1.040v Since the efuse values are'nt currently used, we do not regress on existing pre-production samples (they continue to use nominal voltage). But on boards that do have production samples populated, we can leverage the optimal voltages necessary for proper operation. Tested on: a) 720-2644-001 OMAP5UEVM with production sample. b) 750-2628-222(A) UEVM5432G-02 with pre-production sample.

2017-08-13rockchip: rk3368: add DRAM controller driver with DRAM initialisationPhilipp Tomsich
This adds a DRAM controller driver for the RK3368 and places it in drivers/ram/rockchip (where the other DM-enabled DRAM controller drivers for rockchip devices should also be moved eventually). At this stage, only the following feature-set is supported: - DDR3 - 32-bit configuration (i.e. fully populated) - dual-rank (i.e. no auto-detection of ranks) - DDR3-1600K speed-bin This driver expects to run from a TPL stage that will later return to the RK3368 BROM. It communicates with later stages through the os_reg2 in the pmugrf (i.e. using the same mechanism as Rockchip's DDR init code). Unlike other DMC drivers for RK32xx and RK33xx parts, the required timings are calculated within the driver based on a target frequency and a DDR3 speed-bin (only the DDR3-1600K speed-bin is support at this time). The RK3368 also has the DDRC0_CON0 (DDR ch. 0, control-register 0) register for controlling the operation of its (single-channel) DRAM controller in the GRF block. This provides for selecting DDR3, mobile DDR modes, and control low-power operation. As part of this change, DDRC0_CON0 is also added to the GRF structure definition (at offset 0x600).

2017-08-13rockchip: clk: rk3368: add support for GMAC (SLCK_MAC) clockPhilipp Tomsich
To enable the GMAC on the RK3368, we need to set up the clocking appropriately to generate a tx_clk for the MAC. This adds an implementation that implements the use of the <&ext_gmac> clock (i.e. an external 125MHz clock for RGMII provided by the PHY). This is the clock setup used by the boards currently supported by U-Boot (i.e. Geekbox, Sheep and RK3368-uQ7).

2017-08-13rockchip: clk: rk3368: implement MMC/SD clock reparentingPhilipp Tomsich
The original clock support for MMC/SD cards on the RK3368 suffered from a tendency to select a divider less-or-equal to the the one giving the requested clock-rate: this can lead to higher-than-expected (or rather: higher than supported) clock rates for the MMC/SD communiction. This change rewrites the MMC/SD clock generation to: * always generate a clock less-than-or-equal to the requested clock * support reparenting among the CPLL, GPLL and OSC24M parents to generate the highest clock that does not exceed the requested rate In addition to this, the Linux DTS uses HCLK_MMC/HCLK_SDMMC instead of SCLK_MMC/SCLK_SDMMC: to match this (and to ensure that clock setup always works), we adjust the driver appropriately.

On he RK3368, we need to temporarily disable security on the DMA engines during TPL and SPL to allow the MMC host to DMA into DRAM. To do so, we need to reset the two DMA engines, which in turn requires the DMA1_SRST_REQ and DMA2_SRST_REQ constants to refer to the appropriate bits in the CRU. As the ATF correctly initialises security (and only leaves EL3 after doing so), this can not pose a security issue.

To allow compatibility with Rockchip's DDR init code, we use the same register os_reg2 in pmugrf for passing this info (i.e. DRAM size and configuration) between stages.

2017-07-27rockchip: spl: make boot0 hook TPL safePhilipp Tomsich
When building for a TPL/SPL setup (e.g. on the RK3368), we need the TPL stage to have the extra space for for the 'Rockchip SPL name' (i.e. 'RK33' word). Yet, the SPL will start execution at its first word (i.e. the first word in the SPL binary needs to be a valid instruction). To make things a bit more involved, CONFIG_SPL_BUILD is defined both for the SPL and the TPL stage. To avoid having to explicitly test for the first stage (TPL, if and only if TPL and SPL are built, SPL otherwise), this commit modifies the sequence to repeat the 'b reset' (instead of reserving 4 bytes of undefined space) at the start of the boot0 hook: if overwritten (and execution starts at the second word), the first instruction is still a 'b reset'... if not overwritten, we start on a 'b reset' as well. This solution wouldn't even require the check whether we are in the SPL/TPL build (i.e. CONFIG_SPL_BUILD), but we leave this check in for documentation purposes.
