7915b9914e stm32mp1: pwr: use the last binding for pwr
Update the driver to use the latest binding from kernel v5.5-rc1:
no more use syscon or regmap to access to pwr register and
only one pwr_regulators node with the compatibility "st,stm32mp1,pwr-reg"
is available.

a05eb8b14a arm: xea: dts: Add 'fec-3v3' regulator properties to prevent accidental disablement
The 'enable-active-high' DTS property configures GPIO so it is active with
HIGH state (by default it is low).

The 'regulator-boot-on' property indicates that the regulator was enabled
in the 'earlier' stage - i.e. bootloader/firmware.
In the XEA case the 'fec-3v3' was configured (as a "wrapper" on GPIO0_0) in
very early SPL code, so it shouldn't be modified at latter stages.

14d5aeff77 board: toradex: Add Verdin iMX8M Mini support
This adds initial minimal support for the Toradex Verdin iMX8M Mini Quad
2GB WB IT V1.0A module. They are now strapped to boot from eFuses which
are factory fused to properly boot from their on-module eMMC. U-Boot
supports booting from the on-module eMMC only, SDP support is disabled
for now due to missing i.MX 8M Mini USB support.

Functionality wise the following is known to be working:
- eMMC, 8-bit and 4-bit MMC/SD card slots
- Ethernet
- GPIOs
- I2C

Boot sequence is:
SPL ---> ATF (TF-A) ---> U-boot proper

ATF, U-boot proper and u-boot.dtb images are packed into a FIT image,
loaded by SPL.

79030a4861 rockchip: Add Single boot image (with binman, pad_cat)
All rockchip platforms support TPL or SPL-based bootloader
in mainline with U-Boot proper as final stage. For each
stage we need to burn the image on to flash with respective
offsets.

This patch creates a single boot image component using
- binman, for arm32 rockchip platforms
- pad_cat, for arm64 rockchip platforms.

This would help users to get rid of burning different
boot stage images.

The new image called 'u-boot-rockchip.bin'
which can burn into flash like:

₹ sudo dd if=u-boot-rockchip.bin of=/dev/sda seek=64

This would support all rockchip platforms, except rk3128
since it doesn't support for SPL yet.

43d28855d8 board: Add new Samsung "stemmy" board based on ST-Ericsson U8500
The ST-Ericsson U8500 SoC has been used in mass-production for
some Android smartphones released around 2012.
In particular, Samsung has released more than 5 different
smartphones based on U8500, e.g.

  - Samsung Galaxy S III mini (GT-I8190) "golden"
  - Samsung Galaxy S Advance (GT-I9070)  "janice"
  - Samsung Galaxy Xcover 2 (GT-S7710)   "skomer"

and a few others.

Mainline Linux has great support for the Ux500 SoC, so these
smartphones can also run Linux mainline quite well.

Unfortunately, the original Samsung bootloader used on these devices
has limitations that prevent booting Linux mainline directly.
It keeps the L2 cache enabled, which causes Linux to crash very early,
shortly after decompressing the kernel.

Using U-Boot allows to circumvent these limitations. We can let the
Samsung bootloader chain-load U-Boot and U-Boot locks the L2 cache
before booting into Linux. U-Boot has several other advantages
- it supports device-trees directly and we are no longer limited to
flashing Android boot images through Samsung's proprietary download
mode.

The Samsung "stemmy" board covers all Samsung devices based on U8500.
Add minimal support for "stemmy". For now only UART is supported but
this will be extended later.

689088f9da arm: Add support for ST-Ericsson U8500 SoC
The NovaThor U8500 SoC was released by ST-Ericsson in 2011.
It was used for some development boards like the CALAO Systems
Snowball SBC, but mass production was primarily for Android
smartphones like the Samsung Galaxy S III mini.

Previous support for U8500 was removed in
commit 68282f55b8 ("arm: Remove unused ST-Ericsson u8500 arch")
since none of the boards were converted to generic boards
before the deadline.

The new code does not have much in common with the previous code.
I have completely rewritten everything, embracing the Driver Model
and device trees wherever possible.

The U8500 support is a bit more minimal for now - my primary
use case is to use U-Boot as alternative bootloader for some of the
U8500 Samsung smartphones. At the moment U-Boot is chain-loaded from
the original Samsung bootloader. A side effect of this is that we
can (temporarily) get away without implementing some functionality
- e.g. all clocks are already enabled by the original bootloader.

More functionality will be added in future patches.
