Instead of letting the compiler error out if CONFIG_ENV_IS_NOWHERE is
not selected by the user, let's just enforce it when the user builds for
Ringneck PX30 so that no check needs to be performed by the compiler and
the configuration is always valid.

Now that a single binary containing TPL/SPL correctly formatted for SPI
flashes and U-Boot proper, can be generated by binman, let's do it.
Also update the documentation to tell the user to use this newly
generated file instead of manually generating and flashing the binaries.

The offset of the SPL payload on Puma is different than for other
Rockchip devices in that it is stored at offset 256K instead of much
further away in the MMC.
Flashing one binary instead of two at different offsets is much more
user friendly so let's migrate to it by modifying the offset in the Puma
specific Device Tree.

Depending on the toolchain used to compile the SPL for Puma RK3399-Q7
module, the board does not boot because the resulting binary is too big
to fit in SRAM.
Let's add a TPL so that there's no need to fiddle with or hack the
defconfig to have a working bootloader.
This follows what's been done for the majority of other RK3399-based
boards.
See the original commit for the first migrations:
bdc00080111f "rockchip: rk3399: update defconfig for TPL"
Unfortunately, the offset in SPI-NOR for U-Boot proper needs to be
modified, since the move from SPL to TPL+SPL for idbloader.img (and the
"only the first 2KB per 4KB blocks are written" "hack" for rkspi format)
increased the size above 256KB. Let's move it to 512KB to, hopefully, be
safe.

U-Boot proper
Chances are when one boots U-Boot proper from a given storage medium,
they want the same medium to be used to load and store the environment.
This basically allows to have completely separate U-Boot (TPL/SPL/U-Boot
proper/environment) per storage medium which is convenient when working
with recovery from SD-Card as one would just need to insert a properly
configured SD-Card into the device to have access to their whole debug
setup.
No fallback mechanism is provided as to not dirty other storage medium
environment by mistake. However, since arch_env_get_location() is called
by env_init() which is part of the pre-relocation process, a valid,
non-ENVL_UNKNOWN, value shall be returned otherwise the relocation fails
with the following message:
initcall sequence 00000000002866c0 failed at call 0000000000256b34 (err=-19)
This valid, non-ENVL_UNKNOWN, value is ENVL_NOWHERE which requires to
always select CONFIG_ENV_IS_NOWHERE otherwise this work-around does not
work.

medium
distroboot should try first on the same MMC medium as the one the SPL
loaded U-Boot proper from. This was the case when the introducing commit
was merged because the default order was eMMC first and then SD card.
The check was therefore made only on whether we booted from SD card,
because otherwise the order was the expected one.
However, in commit b212ad24a604 ("rockchip: Fix MMC boot order"), the
order was swapped. Meaning our simple check is now useless.
Let's fix that by accounting for all scenarii: default boot_targets has
mmc0 first but booting from SD Card, mmc1 first but booting from eMMC.

On Puma we have the environment at an offset of 16 kiB.
On the eMMC this gives us 16 kiB for the environment before the SPL starts.
On the SPI NOR we also have 16 kiB until end of flash.

of 16 kiB for both MMC and SPI NOR.

The introduction of the puma-specific generator was mainly a way
to split the pmu firmware from the ATF binary and not having to
distribute that 4GB (sparse) image that was created before moving
to the bl31.elf as base.
Looking at the publically available repository for that separate
pmu firmware
https://git.theobroma-systems.com/rk3399-cortex-m0.git/
there is also no activity for 3 years and apart from some build
customizations no other changes were done.
And even then, if changes need to be made, this can very well also
happen in the atf context itself, so there is no real need to
diverge from the established build procedure and we can just go
back to using the main make_fit_atf.py script.

So far the puma dts files only just included the main puma dtsi without
handling the actual baseboard and rk3399-puma.dtsi was very much
detached from the variant in the mainline Linux kernel.
Recent changes resulted in a strange situation with nonworking puma boards.
Commit ab800e5a6f28 ("arm: dts: rockchip: puma: move U-Boot specific bits to u-boot.dtsi")
moved the sdram include from rk3399-puma-ddrX.dts to new files
rk3399-puma-ddrx-u-boot.dtsi which were never included anywhere though.
Commit 167efc2c7a46 ("arm64: dts: rk3399: Sync v5.7-rc1 from Linux")
replaced the rk3399-puma.dtsi nearly completely, but in the kernel
it definitly depends on a baseboard dts to actually enable peripherals
like sd-slot, uarts, etc.
So to untagle this and bring the whole thing more in line with mainline
Linux, bring the rk3399-puma-haikou.dts over as well, drop the separate
DDR-option devicetrees and instead replace them with a puma Kconfig option
to select and include the needed DDR variant.

This commit adds ENV_SIZE and ENV_OFFSET configuration items for

With these new items present, the configuration from the header files
is moved to Kconfig.
Keeping these non-visible is necessary to have the possibility to
select new default values if CONFIG_IS_IN_* is changed (interactively
or with oldconfig). Otherwise it will always be set to a previous
value if used with a prompt. As an example if we do a defconfig with
CONFIG_IS_IN_MMC and change it to CONFIG_IS_IN_SPI_FLASH via
menuconfig, ENV_SIZE and ENV_OFFSET will not be changed to the correct
values as defconfig will already have set them to the default values
