[PATCH 1/2] rockchip: Use an external TPL binary on RK3308
by Massimo Pegorer 04 Sep '23

04 Sep '23

There is no support to initialize DRAM on RK3308 SoC using U-Boot TPL and therefore an external TPL binary must be used to generate a bootable u-boot-rockchip.bin image. Imply ROCKCHIP_EXTERNAL_TPL by default for RK3308 builds. Remove useless TPL_SERIAL.

[PATCH v2 0/6] Port gen_compile_commands.py from Linux to U-Boot
by Joao Marcos Costa 02 Sep '23

02 Sep '23

Hello U-Boot community, I'm submitting a patch series that ports the gen_compile_commands.py script from the Linux kernel's sources to U-Boot. This script, originally located in scripts/clang-tools/gen_compile_commands.py, enables the generation of compile_commands.json file for improved code navigation and analysis. The series consists of six patches: the initial script import and the necessary modifications for U-Boot compatibility. Your feedback on these contributions would be greatly appreciated. Best regards, Changes in v2: - Add compile_commands.json to gitignore - Add documentation Joao Marcos Costa (6): scripts: Port Linux's gen_compile_commands.py to U-Boot scripts/gen_compile_commands.py: adapt _LINE_PATTERN scripts/gen_compile_commands.py: fix docstring scripts/gen_compile_commands.py: add acknowledgments .gitignore: add compile_commands.json doc: add documentation for gen_compile_commands.py .gitignore | 3 + doc/develop/gen_compile_commands.rst | 46 ++++++ scripts/gen_compile_commands.py | 230 +++++++++++++++++++++++++++ 3 files changed, 279 insertions(+) create mode 100644 doc/develop/gen_compile_commands.rst create mode 100755 scripts/gen_compile_commands.py -- 2.41.0

[PATCH 0/2] thermal: Add VTM driver support for J72xx SOCs
by Udit Kumar 02 Sep '23

02 Sep '23

This series adds VTM (Voltage and Thermal Manager) driver support for J72xx SOCs. Basically this driver is ported from kernel v6.5 to u-boot. Main purpose of this driver to program thermal shutdown value and provide SOC temperature. To use this driver, update in device tree and defconfig are needed. Device tree sync is under review with series https://lore.kernel.org/all/20230822185725.6718-1-reidt@ti.com/ Once above DT sync series will be merged, another patch will be posted to update defconfig. For now marking DT and defconfig update as donotmerge.
