Hello, This series adds a driver for the Aspeed ast2500 FMC/SPI controllers as one can find on the POWER9 OpenPOWER platforms.
It was tested on the AST2500 evb using a w25q256 flash device. Git tree available here: https://github.com/legoater/u-boot/commits/aspeed Thanks, C. Changes since v1: - introduced a new large update of the ast2500 DTS file from Linux - renamed variables in the read calibration algorithm - moved the ast2500 defconfig changes in the patch adding the SPI driver Cédric Le Goater (4): aspeed: ast2500: Add AHB clock spi: Add support for the Aspeed ast2500 SPI controllers aspeed: Update ast2500 Eval Board DTS files to Linux v4.17-rc6 level aspeed: Activate SPI support on the ast2500 Eval Board .../arm/include/asm/arch-aspeed/scu_ast2500.h | 2 + arch/arm/include/asm/arch-aspeed/spi.h | 114 + include/dt-bindings/clock/ast2500-scu.h | 1 + drivers/clk/aspeed/clk_ast2500.c | 12 + drivers/spi/aspeed_spi.c | 791 +++++++ arch/arm/dts/ast2500-evb.dts | 15 + arch/arm/dts/ast2500-u-boot.dtsi | 12 + arch/arm/dts/ast2500.dtsi | 1995 ++++++++++------- configs/evb-ast2500_defconfig | 10 + drivers/spi/Kconfig | 8 + drivers/spi/Makefile | 1 + 11 files changed, 2164 insertions(+), 797 deletions(-) create mode 100644 arch/arm/include/asm/arch-aspeed/spi.h create mode 100644 drivers/spi/aspeed_spi.c -- 2.17.1 _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
