From: Steffen Trumtrar <s.trumtrar@xxxxxxxxxxxxxx> Add support for the Arria10-based Mercury+ AA1 module from Enclustra. Signed-off-by: Steffen Trumtrar <s.trumtrar@xxxxxxxxxxxxxx> --- Changes in v2: - use __dtb_z - use ENTRY_FUNCTION_WITHSTACK - fold aa1_start() into now non-naked entry function - remove arm_early_mmu_cache_invalidate - fix alignment issues arch/arm/boards/Makefile | 1 + arch/arm/boards/enclustra-aa1/Makefile | 4 + arch/arm/boards/enclustra-aa1/board.c | 47 ++++++++ arch/arm/boards/enclustra-aa1/lowlevel.c | 113 ++++++++++++++++++ .../enclustra-aa1/pinmux-config-arria10.c | 104 ++++++++++++++++ .../boards/enclustra-aa1/pll-config-arria10.c | 56 +++++++++ arch/arm/dts/Makefile | 1 + arch/arm/dts/socfpga_arria10_mercury_aa1.dts | 83 +++++++++++++ arch/arm/mach-socfpga/Kconfig | 4 + images/Makefile.socfpga | 12 ++ 10 files changed, 425 insertions(+) create mode 100644 arch/arm/boards/enclustra-aa1/Makefile create mode 100644 arch/arm/boards/enclustra-aa1/board.c create mode 100644 arch/arm/boards/enclustra-aa1/lowlevel.c create mode 100644 arch/arm/boards/enclustra-aa1/pinmux-config-arria10.c create mode 100644 arch/arm/boards/enclustra-aa1/pll-config-arria10.c create mode 100644 arch/arm/dts/socfpga_arria10_mercury_aa1.dts diff --git a/arch/arm/boards/Makefile b/arch/arm/boards/Makefile index d303999614..9d700cfbda 100644 --- a/arch/arm/boards/Makefile +++ b/arch/arm/boards/Makefile @@ -134,6 +134,7 @@ obj-$(CONFIG_MACH_SCB9328) += scb9328/ obj-$(CONFIG_MACH_SEEED_ODYSSEY) += seeed-odyssey/ obj-$(CONFIG_MACH_SOCFPGA_ALTERA_SOCDK) += altera-socdk/ obj-$(CONFIG_MACH_SOCFPGA_EBV_SOCRATES) += ebv-socrates/ +obj-$(CONFIG_MACH_SOCFPGA_ENCLUSTRA_AA1) += enclustra-aa1/ obj-$(CONFIG_MACH_SOCFPGA_REFLEX_ACHILLES) += reflex-achilles/ obj-$(CONFIG_MACH_SOCFPGA_TERASIC_DE0_NANO_SOC) += terasic-de0-nano-soc/ obj-$(CONFIG_MACH_SOCFPGA_TERASIC_DE10_NANO) += terasic-de10-nano/ diff --git a/arch/arm/boards/enclustra-aa1/Makefile b/arch/arm/boards/enclustra-aa1/Makefile new file mode 100644 index 0000000000..5678718188 --- /dev/null +++ b/arch/arm/boards/enclustra-aa1/Makefile @@ -0,0 +1,4 @@ +# SPDX-License-Identifier: GPL-2.0-only + +lwl-y += lowlevel.o +obj-y += board.o diff --git a/arch/arm/boards/enclustra-aa1/board.c b/arch/arm/boards/enclustra-aa1/board.c new file mode 100644 index 0000000000..5b8e5a5c9f --- /dev/null +++ b/arch/arm/boards/enclustra-aa1/board.c @@ -0,0 +1,47 @@ +// SPDX-License-Identifier: GPL-2.0-only + +#include <common.h> +#include <init.h> +#include <io.h> +#include <bbu.h> + +static int aa1_init(void) +{ + int pbl_index = 0;
