2c597855aa ARM: dts: sunxi: H2+/H3/H5: Sync from Linux v5.18-rc1
Copy the devicetree source for the H2+/H3/H5 SoCs and all existing
boards from the Linux v5.18-rc1 tag.

To maintain ABI compatibility with existing LTS kernels, one change
moving some IP blocks to the r_intc interrupt controller is excluded.
This effectively reverts Linux commits 994e5818392c and 9fdef3c3d8c2.

This commit also adds the following new board devicetree:
 - sun8i-h3-nanopi-r1.dts

This update should not impact any existing U-Boot functionality.

70f24fa02b ARM: dts: sunxi: A13/A31/A23/A33: Sync from Linux v5.18-rc1
Copy the devicetree source for the A10s/A13/GR8, A31(s), and A23/A33/R16
SoCs and all existing boards from the Linux v5.18-rc1 tag.

These changes are combined into one commit due to interdependencies:
 - The unit addresses were removed from bitbanged I2C buses, which
   drives a Kconfig default change. This affects sun5i-a13-utoo-p66.dts
   and sun6i-a31-colombus.dts.
 - The pinctrl nodes were renamed, including some used by the shared
   header sunxi-reference-design-tablet.dtsi.

To maintain ABI compatibility with existing LTS kernels, one change
moving some IP blocks to the r_intc interrupt controller is excluded.
This effectively reverts Linux commits 994e5818392c and 9fdef3c3d8c2.

This commit renames the file sun8i-r16-nintendo-nes-classic-edition.dts
to sun8i-r16-nintendo-nes-classic.dts to match the Linux tree.

This commit also adds the following new board devicetrees:
 - sun5i-a13-licheepi-one.dts
 - sun5i-a13-pocketbook-touch-lux-3.dts
 - sun5i-gr8-evb.dts
 - sun8i-a23-ippo-q8h-v1.2.dts
 - sun8i-a23-ippo-q8h-v5.dts
 - sun8i-a33-et-q8-v1.6.dts
 - sun8i-a33-ippo-q8h-v1.2.dts
 - sun8i-r16-nintendo-super-nes-classic.dts

As with the other SoCs, updates of note are conversion of GPIO pull-up
from pinconf to GPIO flags and renaming the detection GPIO properties in
the USB PHY nodes.

290ffe5788 imx8m: fix reading of DDR4 MR registers
I was trying to employ lpddr4_mr_read() to something similar to what
the imx8mm-cl-iot-gate board is doing for auto-detecting the RAM
type. However, the version in drivers/ddr/imx/imx8m/ddrphy_utils.c
differs from the private one used by that board in how it extracts the
byte value, and I was only getting zeroes. Adding a bit of debug
printf'ing gives me

 tmp = 0x00ffff00
 tmp = 0x00070700
 tmp = 0x00000000
 tmp = 0x00101000

and indeed I was expecting a (combined) value of 0xff070010 (0xff
being Manufacturer ID for Micron). I can't find any documentation that
says how the values are supposed to be read, but clearly the iot-gate
definition is the right one, both for its use case as well as my
imx8mp-based board.

So lift the private definition of lpddr4_mr_read() from the
imx8mm-cl-iot-gate board code to ddrphy_utils.c, and add a declaration
in the ddr.h header where e.g. get_trained_CDD() is already declared.

This has only been compile-tested for the imx8mm-cl-iot-gate
board (since I don't have the hardware), but since I've merely moved
its definition of lpddr4_mr_read(), I'd be surprised if it changed
anything for that board.

c329f9349b ARM: imx: imx31: Introduce and use UART_BASE_ADDR(n)
Introduce helper macro UART_BASE_ADDR(n), which returns Nth UART base
address. Convert all board configurations to this new macro. This is the
first step toward switching CONFIG_MXC_UART_BASE to Kconfig. This is a
clean up, no functional change.

The new macro contains compile-time test to verify N is in suitable
range. The test works such that it multiplies constant N by constant
double-negation of size of a non-empty structure, i.e. it multiplies
constant N by constant 1 in each successful compilation case.

The non-empty structure may contain C11 _Static_assert(), make use of
this and place the kernel variant of static assert in there, so that
it performs the compile-time check for N in the correct range. Note
that it is not possible to directly use static_assert in compound
statements, hence this convoluted construct.

For bootloader or OS is this just user button which is worth to have it

Also button can be used as a wakeup source and pressing it for more time
can generate more chars that's why also adding wakeup-source and autorepeat

6e38e2ea79 arm64: zynqmp: Set qspi tx-buswidth to 4
In all the ZynqMP boards dts files tx-buswidth is by default set to 1. Due
to this the framework only issues 1-1-1 write commands to the GQSPI driver.
But the GQSPI controller is capable of handling 1-4-4 write commands, so
updated the tx-buswidth to 4 in ZynqMP boards dts files. This would enable
the spi-nor framework to issue 1-4-4 write commands instead of 1-1-1. This
will increase the tx data transfer rate, as now the tx data will be
transferred on four lines instead on single line.

67bdaa0165 arm64: zynqmp: Fix split mode reset functionality
This patch fixes two issues in the set_r5_reset function.

1. When in split mode, the lpd_amba_rst bit should only be set when
both r5 cpu cores are in reset. Otherwise, if one r5 core is still
running, setting the lpd_amba_rst bit will cause an error for the
running core. The set_r5_reset function has been modified to check
if the other r5 core is still running before setting the lpd_amba_rst
bit.

2. The cpu_disable function was always assuming that the r5 cores
are in split mode when resetting either core 4 or 5. This is
incorrect for lockstep functionality. This patch adds a function
check_r5_mode to handle the cpu_disable function correctly for
the r5 cores by checking the mode and handling the reset appropriately.

5bb2c550b1 arm: mvebu: Move internal registers in arch_very_early_init() function
Moving of internal registers from INTREG_BASE_ADDR_REG to SOC_REGS_PHY_BASE
needs to be done very early, prior calling any function which may touch
internal registers, like debug_uart_init().

So do it earlier in arch_very_early_init() instead of arch_cpu_init().

Movement is done in proper U-Boot, not in SPL. SPL may return to bootrom
and bootrom requires internal registers at (old) expected location.
