The am625-lp-sk is a variant of the am625-sk showcasing the low-power features of the am625 SoC Family. Because it's essentially a board and package spin of the am625-sk I've inherited the am625 configuration and overridden what was needed. This is a new spin of Nitin's original work which has been updated significantly since October 2023 https://lore.kernel.org/u-boot/20231030110138.1347603-1-n-yadav@ti.com/ Unfortunately a few patches have broken the am62x boot currently and need to be added and reverted for this series to work: One to increase the size of MALLOC space to make room for the DM stubs https://lore.kernel.org/u-boot/20240429214936.15187-1-jm@ti.com And this patch (in active debug) will need to be reverted for MMC boot. https://lore.kernel.org/u-boot/20240422190035.25852-1-greg.malysa@timesys.com/ For those of us interested here is proof of life using buildroot: https://paste.sr.ht/~bryanb/40f7787f7760bee383aa8fbc342a29e8544dbdab Thank you for reviewing ~Bryan Signed-off-by: Bryan Brattlof --- Bryan Brattlof (1): configs: add defconfigs for the am625-lp-sk Nitin Yadav (1): arm: dts: add U-Boot dtbs for the am625-lp-sk arch/arm/dts/k3-am62-lp-sk-binman.dtsi | 21 + arch/arm/dts/k3-am62-lp-sk-u-boot.dtsi | 17 + arch/arm/dts/k3-am62-lp4-50-800-800.dtsi | 2190 ++++++++++++++++++++++++++++++ arch/arm/dts/k3-am62-r5-lp-sk.dts | 82 ++ configs/am62x_lp_sk_a53_defconfig | 3 + configs/am62x_lp_sk_r5_defconfig | 2 + 6 files changed, 2315 insertions(+) --- base-commit: b43a0c7ed600fc608262b9a274a1cad4c7465b6a change-id: 20240429-am62q-wip-f3453de038fb Best regards,
