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.

When using DM timers w/ the timer0 block within the RK3368, we no longer depend on the ARMv8 generic timer counting. This allows us to drop the secure timer initialisation from the TPL and SPL stages. The secure timer will later be set up by ATF, which starts the ARMv8 generic timer. Thus, there will be a dependency from Linux to the ATF through the ARMv8 generic timer... this seems reasonable, as Linux will require the ATF (and PSCI) to start up the secondary cores anyway (in other words: we don't add any new dependencies).

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).

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.

Note that (if DM support is enabled), there will be a call to the cache-flushing code from alloc_priv(...) in drivers/core/device.c. This then add 52 bytes of binary size (an increase from 20589 to 20641 bytes) compared to completely removing this code.

2017-08-13rockchip: back-to-bootrom: simplify the #ifdef-check for LIBCOMMON in TPL/SPLPhilipp Tomsich
With the finer-grained control over LIBCOMMON_SUPPORT for TPL/SPL (i.e. with the newly introduced distinction between TPL_LIBCOMMON_SUPPORT and SPL_LIBCOMMON_SUPPORT), we can simplify the #ifdef-check to simply use CONFIG_IS_ENABELD.

2017-08-13rockchip: back-to-bootrom: split BACK_TO_BOOTROM for TPL/SPLPhilipp Tomsich
The back-to-bootrom option is rather unfortunately named CONFIG_ROCKCHIP_SPL_BACK_TO_BOOTROM instead of CONFIG_SPL_ROCKCHIP_BACK_TO_BOOTROM To make is selectable through CONFIG_IS_ENABLED(ROCKCHIP_BACK_TO_BOOTROM), we need to rename it. At the same time, we introduce a TPL_ variant of the option to give us finer-grained control over when it should be used. This change is motivated by our RK3368 boot process, which returns to the boot ROM only from the TPL stage, but not from the SPL stage.
