326e05c5e2 clk: renesas: Add and enable CPG reset driver
Add trivial reset driver extension to the CPG clock driver. The change
turns current CPG UCLASS_CLK driver instance into an UCLASS_NOP proxy
driver, which in turn binds both generic rcar3_clk UCLASS_CLK clock
driver as well as generic rcar_rst UCLASS_RESET reset driver to the
CPG DT node. This way, any other drivers which use the 'reset' DT
property can now obtain valid reset handle backed by a reset driver.

The clock tables have been updated to represent the CPG driver and only
implement the generic CPG proxy driver bind call, which binds the clock
and reset drivers.

The DM_RESET is now enabled for all R-Car Gen3 platforms.

d3655bbb13 ARM: arm: colibri-imx6ull-emmc: fix emmc access
Synchronizing the device tree with linux introduced a regression.
The U-Boot specific dtsi mustn't override the alias settings for
the eMMC/SD interfaces.

Without this U-Boot cannot access the eMMC and boot the kernel.

ed50f82ceb arm: imx: imx8m: Add basic PSCI provider implementation
Implement basic PSCI provider to let OS turn CPU cores off and on,
power off and restart the system and determine PSCI version. This
is sufficient to remove the need for the ATF BL31 blob altogether.

To make use of this functionality, active the following Kconfig options:
  # CONFIG_PSCI_RESET is not set
  CONFIG_ARMV8_MULTIENTRY=y
  CONFIG_ARMV8_SET_SMPEN=y
  CONFIG_ARMV8_SPL_EXCEPTION_VECTORS=y
  CONFIG_ARMV8_EA_EL3_FIRST=y
  CONFIG_ARMV8_PSCI=y
  CONFIG_ARMV8_PSCI_CPUS_PER_CLUSTER=4
  CONFIG_ARMV8_SECURE_BASE=0x970000
  CONFIG_ARM_SMCCC=y
  CONFIG_SYS_HAS_ARMV8_SECURE_BASE=y

58552ab81b arm: imx: imx8m: Program CSU and TZASC if PSCI provider
In case U-Boot is the PSCI provider, it is necessary to correctly
program CSU and TZASC registers. Those are poorly documented, so
push in the correct values.

191937134b arm: imx: imx8m: Define trampoline location if PSCI provider
The common code used to bring up secondary cores requires a final
jump location to be stored in some sort of memory location, define
this memory location to be the start of OCRAM, since it is available.

1434f93ee0 arm: imx: imx8m: Map RAM as NS if PSCI provider
In case U-Boot is a PSCI provider, map RAM explicitly as NS,
otherwise secondary cores crash with SError when attempting
to access RAM mapped as secure in EL2.

45dd377e36 arm: imx: imx8m: Only use ROM pointers if not PSCI provider
The ROM pointers are in fact populated by the ATF BL31 blob, in case
U-Boot itself if the PSCI provider, there is no ATF BL31 blob, hence
ignore the ROM pointers.

9694c0532a arm: dts: imx8m: Require ATF BL31 blob only if not PSCI provider
In case U-Boot itself if the PSCI provider on i.MX8M, do not
require the ATF BL31 blob, as at that point the blob is useless
and would interfere with U-Boot operation.

ae237b1e62 arm: imx: Drop custom lowlevel_init
The custom lowlevel_init implementation is no longer necessary, since
it is responsible for routing and trapping SErrors in U-Boot in EL2,
which is implemented in common code since commit:
6c7691edd5 ("armv8: Always unmask SErrors")
