arm: dts: rockchip: Fix eMMC write on RK3528

2025-06-15T16:30:41+00:00

Writing to eMMC on RK3528 is affected with the same or a similar issue
as on RK3588, where eMMC must init to HS200 at least once to fully work.

Trying to write u-boot-rockchip.bin to eMMC fails with:

  => mmc write $fileaddr 40 5000
  MMC write: dev # 0, block # 64, count 20480 ... mmc write failed
  0 blocks written: ERROR

For U-Boot to enable HS200 mode the mmc-hs200-1_8v prop must be defined
in the device tree. Linux does not seem to be affected and is able to
detect and use HS200 without this prop.

Enable use of HS200 and fix eMMC write on RK3528 by adding the missing
mmc-hs200-1_8v prop for affected boards:

  => mmc write $fileaddr 40 5000
  MMC write: dev # 0, block # 64, count 20480 ... 20480 blocks written: OK

Merge patch series "arm: armv7: fix a bug that prevents CONFIG_BLOBLIST and CONFIG_POSITION_INDEPENDENT to be enabled together"

Yang Xiwen  says:

This patchset also enables CONFIG_POSITION_INDEPENDENT for qemu boards
to avoid similar issues to happen again in the future.

arm: qemu: Add imply CONFIG_POSITION_INDEPENDENT

2025-06-09T15:18:17+00:00

Add 'imply CONFIG_POSITION_INDEPENTDENT' for QEMU arm arch. This allows
qemu arm boards to load u-boot.bin at any address. It is skipped by
default when u-boot is loaded by either --bios or --kernel.

To load u-boot.bin at a different address, one can use u-boot
chain-loading or qemu loader device[1].

arm: armv7: restore section to .text after saved_args

2025-06-09T15:18:17+00:00

when CONFIG_BLOBLIST is enabled, the section is switched to .data but is
not switched back to .text. It makes all the code below placed in .data
section, also breaks CONFIG_POSITION_INDEPENDENT.

Fix it by adding `.section .text` to switch the section back to .text.

rockchip: rk3399-nanopi-4: Enable IO-domain driver in SPL

2025-06-06T09:21:54+00:00

The NanoPi RK3399 boards support UHS-I (up to SDR104) SD cards, however
using any of these 1.8v modes results in a boot failure in SPL upon soft
reboot.

The issue is that the "vcc_sdio" regulator is left at 1.8v on reboot
and the corresponding GPIO defaults to 3.3v. This prevents the SD card
from being reinitialized and read successfully.

This change enables the RK8XX regulators and Rockchip IO-domain drivers
in SPL, which initializes "vcc_sdio" regulator to 3.0v and configures
the GPIO for the correct level on boot.

rockchip: rk3399-nanopi-4: Allow MMC driver to control SD regulators

2025-06-06T09:21:54+00:00

This change removes the "regulator-always-on" property from the
"vcc3v0_sd" (vmmc-supply) and "vcc_sdio" (vqmmc-supply) regulators,
which otherwise prevents the MMC driver from being able to power cycle
the SD card as part of the initialization procedure.

It also removes the "regulator-boot-on" from the "vcc_sdio" regulator,
which could theoretically damage a SD card that is already initialized
in a low voltage mode.
