When RK3399 boards run SPL from eMMC and fail to load FIT from eMMC due
to it being missing or checksum validation fails there can be a fallback
to read FIT from SD-card. However, without proper pinctrl configuration
reading FIT from SD-card may fail:
U-Boot SPL 2024.04-rc4 (Mar 17 2024 - 22:54:45 +0000)
Trying to boot from MMC2
mmc_load_image_raw_sector: mmc block read error

Card did not respond to voltage select! : -110
mmc_init: -95, time 12
spl: mmc init failed with error: -95
SPL: failed to boot from all boot devices (err=-6)
### ERROR ### Please RESET the board ###
Fix this by tagging related sdhci, sdmmc and spi flash pinctrl nodes
with bootph props. Also move bootph for common nodes shared by all
boards to the SoC u-boot.dtsi.
eMMC, SD-Card and SPI flash nodes are also changed to only be tagged
with bootph props for SPL and U-Boot pre-reloc phases.

The initial serial console UART iomux is typically configured in
board_debug_uart_init() at TPL stage on Rockchip platform.
Later stages typically use pinctrl driver to configure iomux UART once
again based on the control FDT.
Include uart related pinctrl nodes in TPL/SPL control FDT to make it
possible for pinctrl driver to configure UART iomux at TPL/SPL stage.
Following debug log message may also be seen at U-Boot pre-reloc stage:
ns16550_serial serial@ff1a0000: pinctrl_select_state_full: uclass_get_device_by_phandle_id: err=-19
This can be resolved by including bootph prop for U-Bood pre-reloc
phase (bootph-some-ram or bootph-all). However, this has intentionally
been excluded due to including it unnecessarily slows down boot around
200-400 ms.
Also add the clock-frequency prop similar to what has been done for
other Rockchip SoCs.

A lot of RK3399 boards use a u-boot,spl-boot-order of "same-as-spl",
&sdhci and &sdmmc.
Move this to rk3399-u-boot.dtsi and make this default for boards
currently missing a u-boot,spl-boot-order prop.
Before commit a7e69952eb6d ("rockchip: spl: Cache boot source id for
later use") it was required to include the SPI flash node in the
u-boot,spl-boot-order prop to successfully load FIT from SPI flash.
The SPI flash node reference has been dropped from spl-boot-order from
pinebook-pro, roc-pc and rockpro64 now that "same-as-spl" also gets
resolved to the SPI flash node and loading FIT from SPI flash works
without having the node explicitly referenced in spl-boot-order prop.

This is a subset of [1]. With more platform maintainers switching to
OF_UPSTREAM I didn't want to get in the way (it has also proven more
difficult than I hoped to remove only the fully compatible header
files).
This series removes only the dt-bindings headers which contain generic
data like GPIO flags, input event codes, etc.
It then implements support for building all DTBs for a vendor with
OF_UPSTREAM_BUILD_VENDOR. This removes the need to maintain a set list
of DTBs that can be built by U-Boot and opens up the possibility of new
boards becoming supported "by default" just by landing their DT
upstream.

This series has been tested on AM65x SR2.0, and the ICSSG interface is

The users need to set env variables fw_storage_interface, fw_dev_part,
fw_ubi_mtdpart, fw_ubi_volume to indicate which storage medium and
partition they want to use to load firmware files from. By default the env
fw_storage_interface=mmc and fw_dev_part=1:2 but users can modify these

In Linux, we allow sleep moci to be turned off when the carrier board
supports it and the system is in suspend. In U-Boot, however, we want
the sleep moci to be always on. So we use a gpio hog and disable the

device tree files with commit c07bba7a2c7e ("verdin-am62: move verdin
am62 to OF_UPSTREAM"). A recent upstream patch removes the gpio hog from
the Linux device tree, so we need to add it to the u-boot dtsi. The

When Rockchip TPL blob is used, the memory areas that can be used for
DRAM is gotten from ATAGS passed through the DRAM at a specific address.
The DDR_MEM tag contains at most 10 areas, so we should default to 10 if
Rockchip TPL blob is used. Note that it is technically possible we need
more if one of those 10 areas overlaps with reserved memory area,
forcing us to split it in two. But a default doesn't need to handle all

Allow RK3568 and RK3588 based boards to get the RAM bank configuration
from the ROCKCHIP_TPL stage instead of the current logic. This fixes
both an issue where 256MB of RAM is blocked for devices with >= 4GB
of RAM and where memory holes need to be defined for devices with
more than 16GB of RAM. In the event that neither SoC is used or the
ROCKCHIP_TPL stage is not used, fall back to existing logic.
The logic handles creating memory holes from reserved memory areas
defined in mem_map data struct in SoC C files, but only if the DRAM area
overlaps with one reserved memory area.
Since mem_map data struct is used, it should be rather straightforward
to add support for other SoCs if needed.
The logic is taken from Rockchip's U-Boot tag linux-5.10-gen-rkr4.1
(e08e32143dd).
Note that Rockchip's U-Boot/TF-A/OP-TEE modify the ATAGS at runtime as
well, but the DDR_MEM tag seems to be pretty much stable (though BL31
seems to be reserving only 1MB for itself at the moment).
u32 for ATAGS is used because it simplifies the pointer arithmetic and
it's expected that ATAGS are always below the 4GB limit allowed by u32.

Some variants of the ROCK Pi 4 series have an SPI flash chip populated
which can be booted from. This patch enables support in U-Boot for
building the image for the SPI flash, support for booting U-Boot from the
SPI flash chip and support in U-Boot for accessing the SPI flash using
`sf` commands.
Not all variants (e.g. ROCK Pi 4B, ROCK 4 Model C Plus, ROCK 4SE) come
populated with an SPI flash chip, but have the footprint on the board so
a user could solder their own to the board. With this patchset applied,
these board variants without an SPI flash chip still boot from MMC.
I have enabled support for both Winbond and XTX SPI flash devices since
different hardware variants have different devices populated:
- `rockpi4_v13_sch_20181112.pdf` contains a Winbond part `W25Q64FWZPIG`
- `rockpi4_v14_sch_20210114.pdf` contains an XTX part `XT25F32BWOIGT`
The ROCK Pi 4 I have is marked as "ROCK PI 4 v1.48" and contains an SPI
flash chip from XTX:
=> sf probe
SF: Detected xt25f32 with page size 256 Bytes, erase size 4 KiB, total 4 MiB
In the interest of supporting all board variants and not regressing
existing users who boot from MMC, I have enabled support for booting from
both SPI flash chip variants in the defconfig and left the environment
storage location as MMC to not break existing users who have the
environment stored on MMC.
