[PATCH v2] adc: rockchip-saradc: add support for getting reference voltage value
by Peter Cai 14 Mar '22

14 Mar '22

Mirroring commit 97ab802aa36f ("adc: meson-saradc: add support for getting reference voltage value") for meson-saradc, this adds support for getting the "vref-supply" regulator and register it as the ADC's reference voltage regulator, so clients can translate sampled ADC values to voltage.

[PATCH] rockchip: Set default LNX_KRNL_IMG_TEXT_OFFSET_BASE to SYS_TEXT_BASE
by Alper Nebi Yasak 14 Mar '22

14 Mar '22

U-Boot can be chainloaded from vendor firmware on ARM64 chromebooks from a GPT partition (roughly the same as in doc/chromium/chainload.rst), but an appropriate image header must be built-in to the U-Boot binary by enabling LINUX_KERNEL_IMAGE_HEADER. This header has a field for an image load offset from 2MiB alignment which must also be customized through LNX_KRNL_IMG_TEXT_OFFSET_BASE. Set it equal to SYS_TEXT_BASE by default for Rockchip boards, which happens to make this offset zero and works fine on chromebook_kevin both for chainloading and bare-metal use. Signed-off-by: Alper Nebi Yasak <alpernebiyasak(a)gmail.com> --- Looks like ARM64 chromebooks also need POSITION_INDEPENDENT=y to chainload that way, but I'm not enabling the configs here.

In Manjaro ARM we have used this patch for years now and it was requested that we upstream it. This will make all rk3399 based boards try USB boot before SD or eMMC.

[PATCH] arm: dts: rk3399-puma: re-add vdd_log for uboot
by Heiko Stuebner 14 Mar '22

The rk3399-puma board needs a 950mV vdd_log to work stable. This was already added in commit 77012e79ffc3 ("rockchip: rk3399-puma: Set VDD_LOG to 950 mV") but lost again with commit 167efc2c7a46 ("arm64: dts: rk3399: Sync v5.7-rc1 from Linux") So to make puma stable again re-add the vdd_log pwm regulator. As it is not part of the mainline Linux dts right now, add it to the -u-boot dtsi for puma.

[PATCH 0/8] video: improve UEFI experience on DM_VIDEO
by Andre Przywara 13 Mar '22

13 Mar '22

While U-Boot supported graphical output on monitors for ages, the actual user experience on the DM_VIDEO console is somewhat lacking, especially when UEFI applications use the screen via boot services. This series fixes some of the shortcomings: - Patch 1 includes a rudimentary cursor output, which so far was completely missing from the (DM_VIDEO) console. - Patches 2-5 add support for larger bitmap fonts, which are helpful on high resolution screens as found on modern laptops, for instance. These also pull in two larger bitmaps fonts from the Linux kernel. - Patches 6-8 fix the display of those fonts when used by UEFI applications, which assume Unicode encoding. Beside the actual mapping function this also adds some EFI selftests, which would need to be verifed manually on the screen. The last three patches are somewhat less refined, they probably require some more discussion. Please have a look!

[PATCH v10 0/9] env: Allow environment in text files
by Simon Glass 12 Mar '22

12 Mar '22

One barrier to completing the 7-year-long Kconfig migration is that the default environment is implemented using ad-hoc CONFIG options. At present U-Boot environment variables, and thus scripts, are defined by CONFIG_EXTRA_ENV_SETTINGS. It is not really feasible to move the environment to Kconfig as it is hundreds of lines of text in some cases. Even considering the current situation, it is painful to add large amounts of text to the config-header file and dealing with quoting and newlines is harder than it should be. It would be better if we could just type the script into a text file and have it included by U-Boot. This is already supported by the CONFIG_USE_DEFAULT_ENV_FILE feature. but that does not support use of CONFIG options or comments, so is best suited for use by other build systems wanting to define the U-Boot environment. Add a feature that brings in a .env file associated with the board config, if present. To use it, create a file board/<vendor>/<board>.env or use CONFIG_ENV_SOURCE_FILE to set a filename. The environment variables should be of the form "var=value". Values can extend to multiple lines. This series converts the existing environment documentation to rST and updates it to explain how to use this. Note: this series was originally sent eight years ago: https://patchwork.ozlabs.org/project/uboot/patch/1382763695-2849-4-git-send… It has been updated to work with Kconfig, etc. Some review comments in that patch were infeasible so I have not addressed them. I would like this series to be considered independently, on its merits. Rather than deal with the complexity of rewriting the distro-boot script, this is disabled for sandbox. The forthcoming bootmethod approach should provide the same functionality without needing the complex scripting in the environment. Migration needs more thought, although it can be done later. It may be possible to do migrate automatically, using buildman to extract the built-in environmnent from the ELF file. This would produce a pretty ugly conversion though, since it would drop all the intermediate variables used to create the environment. Better would be to parse the config.h file, figure out the components of CONFIG_EXTRA_ENV_SETTINGS then output these as separate pieces in the file. It is not clear how easy that would be, nor whether the result would be very pretty. Also the __stringify() macro needs to be handled somehow. This series is available at u-boot-dm/env-working Comments welcome.
