U-Boot proper automatically modifies boot_targets to swap the order in
which MMC storage media are used for standard boot based on which MMC
storage medium was used to load U-Boot proper. This is however only done
if the user has not changed it manually, therefore a check between the
default and current value is done.
This used to work fine until the migration to standard boot where
boot_targets value size in the default environment went above the 32
characters that env_get_default function can return, thus resulting in a
truncated variable.
Therefore the check between default and current value would always fail.
By using the newly added env_get_default_into function, a buffer of
the appropriate size can be allocated on the stack to get the whole
value of boot_targets in the default environment and thus fixing the
check.

It's happened that glitches on the STM32_RST and STM32_BOOT lines have
put the STM32 companion microcontroller into DFU mode making it not boot
its FW, rendering it useless for the user.
Considering that the STM32 companion microcontroller is always reset on
a reboot or power cycle, resetting it once again in U-Boot SPL isn't
going to hurt it any more.
For ATtiny companion microcontroller, the situation is a bit different
because a reboot or power cycle doesn't reset it. Additionally, since it
can only be reset with a UPDI reset on the STM32_RST line, and that is
virtually impossible to mistakenly trigger, the ATtiny is unlikely to be
in unwanted reset or enter reset because U-Boot toggles STM32_RST line.

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.

boards.
See the original commit for the first migrations:
bdc0008011 "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

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.

because otherwise the order was the expected one.
However, in commit b212ad24a6 ("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.

Recent changes resulted in a strange situation with nonworking puma boards.
Commit ab800e5a6f ("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 167efc2c7a ("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.
