Introduce common variables to define a generic build instruction that is
then used in specific board specific description.
Labels are introduced in the evm.rst files to be then reused in variant
board documentation as well.
While at this, drop using ARCH=arm when building u-boot sources. This
practice has been discouraged for some time and can potentially create
problems with Kconfig rules related to aarch64. It's best to avoid
this approach.

Having saved environments usually causes inconsistencies while in
development workflow. The saved environments conflict with the
default ones that U-boot should be updating during development
but that doesn't happen and the saved environments need to be
reset during bootups to test the changes causing extra debugs.
Remove the saved environments as a default. Environments can always
be re-enabled locally if one does like them or needs them for
some production environment. Optionally, Uenv.txt can also be used on
some of the boot media.

In non-combined boot flow for K3, all the firewalls are locked by default
until sysfw comes up. Rom configures some of the firewall for its usage
along with the SRAM for R5 but the PSRAM region is still locked.
The K3 MCU Scratchpad for j721e was set to a PSRAM region triggering the
firewall exception before sysfw came up. The exception started happening
after adding multi dtb support that accesses the scratchpad for reading
EEPROM contents.
The commit changes R5 MCU scratchpad for j721e to an SRAM region.

The Anbernic RGxx3 is a "pseudo-device" that encompasses the following
devices:
- Anbernic RG353M
- Anbernic RG353P
- Anbernic RG353V
- Anbernic RG353VS
- Anbernic RG503
The rk3566-anbernic-rgxx3.dtsi is synced with upstream Linux, but
rk3566-anbernic-rgxx3.dts is a U-Boot specific devicetree that
is used for all RGxx3 devices.
Via the board.c file, the bootloader automatically sets the correct
fdtfile, board, and board_name environment variables so that the
correct devicetree can be passed to Linux. It is also possible to
simply hard-code a single devicetree in the boot.scr file and use
that to load Linux as well.
The common specifications for each device are:
- Rockchip RK3566 SoC
- 2 external SDMMC slots
- 1 USB-C host port, 1 USB-C peripheral port
- 1 mini-HDMI output
- MIPI-DSI based display panel
- ADC controlled joysticks with a GPIO mux
- GPIO buttons
- A PWM controlled vibrator
- An ADC controlled button
All of the common features are defined in the devicetree synced from
upstream Linux.
