The input clock for uart is too slow (25MHz) which introduces frequent data
error on both receiving and transmitting even if the baudrate is 115200.
Using high-speed can significantly solve this issue.

This patch adds general board files based on MT7981 SoCs.
MT7981 uses one mmc controller for booting from both SD and eMMC, and the
pins of mmc controller are also shared with spi controller.
So three configs are need for these boot types:
1. mt7981_rfb_defconfig - SPI-NOR and SPI-NAND
2. mt7981_emmc_rfb_defconfig - eMMC only
3. mt7981_sd_rfb_defconfig - SD only

1. mt7986_rfb_defconfig - SPI-NOR and SPI-NAND for MT7986A/B
2. mt7986a_bpir3_emmc_defconfig - eMMC for MT7986A only

First set of u-boot-at91 features for the 2023.01 cycle:
This feature set includes the important update on PIO4 pinctrl driver
that solves a long time mismatch between Linux and U-boot, related on
the unification of pinctrl and gpio driver support, now respecting the
pinctrl bindings ABI; and also support for pinctrl subnodes. The feature
set also adds support for PDA screen detection for sam9x60_curiosity
board , one fix for SD-Card reinsertion and one fix for sam9x60 clocks.
Adding the "u-boot,dm-pre-reloc" DT property to the timer node is
necesssary to support the timer in the early boot phases (e.g.
SPL & pre-reloc).

When the imx8mm.dtsi file was pulled in from Linux, the UARTs
were moved into an spba sub-node which wasn't being included
in the SPL device tree. This meant the references to the UART
weren't being handled properly and when booting the system would
constantly reboot. Fix this by adding the spba node to the spl
device tree to restore normal booting.

Commit 6337d53fdf ("arm: dts: sync am33xx with Linux 5.9-rc7") syncs
the am335x device tree with the latest linux kernel am335x device tree.
That causes problems with device tree in SPL stage.
To fix the issues CONFIG_SPL_OF_TRANSLATE must be set to handle the
synced bus addresses correctly.
A custom U-Boot device tree is also needed since the SPL build removes
bus properties from bus nodes which are not explicitly marked with the
u-boot,dm-spl or u-boot,dm-pre-reloc flag. Therefore all parent buses of
the in the SPL needed devices must be marked with u-boot,dm-pre-reloc.
Also since there is no driver for "ti,sysc" compatible property in SPL
the buses marked with this compatible string must also be marked with
compatible = "simple-bus" to make the underlying devices visible in
SPL. Otherwise the matching device drivers aren't found and the uclass
drivers are dropped.

Removes hwlocks properties from stm32mp151 pinctrl node. These locks
could be used for other purpose, depending on board and software
configuration hence do not enforce their use to protect pinctrl
devices.
This patch is an alignment with Linux device tree with v6.0 as the
hwsem support wasn’t yet added in pincontrol in kernel. It avoids
issues when the Linux kernel is started with the U-Boot device tree.

Tree Bindings.
Correct them in both DTSi files and drivers, to match the final DT
Bindings.
Note that there are no DT bindings for RPC-IF on RZ/A1 yet, hence the
most logical SoC-specific value is used, without specifying a
family-specific value.

According to the Generic Names Recommendation in the Devicetree
Specification Release v0.3, and the DT Bindings for the Renesas Reduced
Pin Count Interface, the node name for a Renesas RPC-IF device should be
"spi". Especially on R-Car Gen3 and RZ/G2, the node name matters, as
the node is enabled by passing a DT fragment from TF-A to U-Boot, and
from U-Boot to subsequent software.
Fix this by renaming the device nodes from "rpc" to "spi".
