As should be clear for the title and patch title, this is adding initial support for the OMAP 4460 SOM and dev kit for Phytec's PCM959 evaluation kit. The PCM049 is a legacy SOM offered by Phytec: https://www.phytec.com/legacy-soms/ There was a vendor BSP offered by Phytec, but that never entered the Device Tree era. This patch is meant to change that. My development bootloader has moved to U-Boot, but I have verified Barebox works in the past. When booting from SD card, either bootloader should work. When booting from Barebox, the NAND OOB layout is incompatible between the bootloader and the kernel. I haven't had any OOB / ECC errors in the NAND at all, which was my main concern. Due to that, I'm submitting this as a patch instead of an RFC. Hardware ECC correction seems to be fully functional. v2->v3 * Acked-by on patch 1 * Code review changes (see patch 2 for details) * Fix intermittent NAND failures (patch 2) v1->v2 * Almost everything moved into the SOM (PCM-049) .dtsi. Only the LED chip is dev-board specific. * Fix pinmux associations (*pmx_core was applying *pmx_wkup entries... I'm surprised that didn't cause more issues) * Documentation added * Updates from review: * Board compatible strings added * Hyphen / underscore changes * Remove unnecessary status="okay" entries * Generic names used (regulator, led-1, etc.) Colin Foster (2): dt-bindings: arm: omap: add phytec pcm-049 som and pcm-959 dev board arm: dts: omap4: pcm959: add initial support for phytec pcm959 .../devicetree/bindings/arm/omap/omap.txt | 3 + arch/arm/boot/dts/Makefile | 1 + arch/arm/boot/dts/omap4-phytec-pcm-049.dtsi | 400 ++++++++++++++++++ arch/arm/boot/dts/omap4-phytec-pcm-959.dts | 48 +++ 4 files changed, 452 insertions(+) create mode 100644 arch/arm/boot/dts/omap4-phytec-pcm-049.dtsi create mode 100644 arch/arm/boot/dts/omap4-phytec-pcm-959.dts -- 2.25.1
