This series adds the pieces needed to fully configure the TI AM654x EVM and its associated (optional) daughtercards using a GPIO-based card presence detection scheme. It then reads out and parses any I2C EEPROM data present on any such boards for example board name, serial #, Ethernet MAC addresses, etc. and incorporates this data into the current U-Boot environment. One important aspect is the application of daughercard-specific DTB overlays right before the Kernel boot happens.
This series also adds basic I2C support for TI K3 family devices which is a prerequisite for the EEPROM access. -- Andreas Dannenberg Texas Instruments Inc Andreas Dannenberg (16): arm: dts: k3-am65: Move pinctrl nodes out of U-Boot specific dtsi arm: dts: k3-am65: Add I2C nodes arm: dts: k3-am654-base-board: Enable wkup_i2c0 across all boot stages configs: am65x_evm_defconfig: Enable I2C support configs: am65x_hs_evm_defconfig: Enable I2C support arm64: dts: k3-am654-base-board: Add I2C GPIO expander @ 0x38 configs: am65x_evm_a53: Enable PCA953X-type GPIO driver configs: am65x_hs_evm_a53: Enable PCA953X-type GPIO driver configs: am65x_evm_a53: Increase malloc pool before relocation configs: am65x_hs_evm_a53: Increase malloc pool before relocation arm: K3: am654: Map common EEPROM data into SRAM scratch space ti: common: am6: Add support for board description EEPROM ti: common: am6: Add support for setting MAC addresses board: ti: am654: Use EEPROM-based board detection configs: am65x_evm: Add support for applying overlays configs: am65x_hs_evm: Add support for applying overlays Vignesh R (2): i2c: omap24xx_i2c: Adapt driver to support K3 devices arm: omap_i2c: Remove unwanted header file inclusion arch/arm/dts/k3-am65-main.dtsi | 60 +++++ arch/arm/dts/k3-am65-mcu.dtsi | 11 + arch/arm/dts/k3-am65-wakeup.dtsi | 19 ++ arch/arm/dts/k3-am65.dtsi | 7 + arch/arm/dts/k3-am654-base-board-u-boot.dtsi | 35 +-- arch/arm/dts/k3-am654-base-board.dts | 22 ++ arch/arm/dts/k3-am654-r5-base-board.dts | 13 + arch/arm/include/asm/omap_i2c.h | 2 - arch/arm/mach-k3/am6_init.c | 4 + arch/arm/mach-k3/include/mach/am6_hardware.h | 3 + arch/arm/mach-k3/include/mach/sys_proto.h | 2 + board/ti/am65x/Kconfig | 7 + board/ti/am65x/evm.c | 241 ++++++++++++++++++ board/ti/common/board_detect.c | 246 +++++++++++++++++++ board/ti/common/board_detect.h | 206 ++++++++++++++++ configs/am65x_evm_a53_defconfig | 11 +- configs/am65x_evm_r5_defconfig | 4 + configs/am65x_hs_evm_a53_defconfig | 11 +- configs/am65x_hs_evm_r5_defconfig | 4 + drivers/i2c/Kconfig | 2 +- include/configs/am65x_evm.h | 18 +- 21 files changed, 892 insertions(+), 36 deletions(-) -- 2.17.1 _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
