rockchip: puma-rk3399: migrate to u-boot-rockchip.bin
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.
The SPL payload offset when booting from SPI defaults to
CONFIG_SYS_SPI_U_BOOT_OFFS but can be overridden by
u-boot,spl-payload-offset. The Device Tree for Puma Haikou has this
property so there's no need to have this one option in the defconfig,
especially since they are not in sync and therefore confusing.
rockchip: puma-rk3399: load environment from same medium as one used to load 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.
rockchip: puma-rk3399: allow loading environment from SPI-NOR flash
There's a SPI-NOR flash available from which SPL and U-Boot proper can
be booted, it makes sense to also allow this medium to store U-Boot
environment so let's enable it.
The Device Tree advertises a max frequency of 50MHz so let's set the
config option appropriately.
rockchip: puma-rk3399: load environment from same MMC as used for loading U-Boot proper
Automatically detect which MMC device (SD-Card or eMMC) was used to load
U-Boot proper and load the environment from that MMC device instead of

rockchip: puma-rk3399: allow non-SD-Card-loaded SPL to load U-Boot proper from SD-Card
Trying to load U-Boot proper from SPL when SPL was not loaded from
SD-Card is currently not working because the SDMMC pins aren't muxed
correctly. It is assumed the BootROM is doing this for us when booting
from SD-Card hence why it's not needed when booting TPL/SPL from
SD-Card.
The pinctrl properties are removed from the SPL DT property removal list
and the pinctrl configuration nodes made available in the SPL DT, in
addition to the pull-up configurations to allow loading U-Boot proper
from SD-Card as a fallback mechanism for SPI-NOR and eMMC.
