ram: aspeed: add SDRAM controller driver for AST2700

2026-06-29T19:43:21Z

Add a SDRAM controller driver for the AST2700, derived from the existing AST2700 controller code used by the Ibex SPL but adapted to run from ARM U-Boot proper on the Cortex-A35 cores. The DDR4/DDR5 controller and its DesignWare PHY are programmed by the Ibex SPL before ARM U-Boot proper takes over. This driver reads back the configuration left by the SPL, probes the controller, and exposes ram_info (base and size, with the VGA carve-out subtracted) via UCLASS_RAM so that dram_init() can populate gd->ram_size. The PHY firmware-load entry points (dwc_ddrphy_phyinit_userCustom_*) are kept compiled but call a __weak fmc_hdr_get_prebuilt() stub when ARM U-Boot proper is the caller; the real implementation is provided by the Ibex SPL via the same fmc_hdr.h descriptor format (here added for the ARM build). Adds the supporting register-layout headers under arch/arm/include/asm/arch-aspeed/: - sdram.h: SDRAM controller and DWC PHY register definitions - scu.h: SCU bits referenced by the SDRAM driver - fmc_hdr.h: prebuilt-blob descriptor (binary-compatible with arch/riscv/include/asm/arch-ast2700/fmc_hdr.h used by the Ibex SPL) Signed-off-by: Ryan Chen

arm: aspeed: add ASPEED AST2700 SoC family support

2026-06-29T19:43:20Z

Add initial support for the ASPEED AST2700, an arm64 (Cortex-A35) Baseboard Management Controller (BMC) SoC. AST2700 is Aspeed's 8th generation BMC and uses a dual-die architecture: SoC0 (the "CPU" die) hosts the four Cortex-A35 cores and its own SCU at 0x12c02000, while SoC1 (the "IO" die) hosts the peripherals and its own SCU at 0x14c02000. This commit adds: - ASPEED_AST2700 Kconfig option and the ast2700 mach subdir (mach Makefile, ast2700/Kconfig, board/aspeed/evb_ast2700/*) - arm64 MMU map covering the SoC device window and the DRAM region at 0x4_0000_0000 (up to 8 GiB) - lowlevel_init.S for early CPU bring-up - cpu-info: print SoC ID (AST2700/2720/2750 A0/A1/A2 variants) and reset cause (cold reset, EXT reset, WDT reset) - board_common: dram_init via UCLASS_RAM, AHBC timeout init - platform: env_get_location() that selects SPI/eMMC based on the IO-die HW strap; arch_misc_init() that exposes ${boot_device} and ${verify} to the boot script - SCU0/SCU1 register layout header (scu_ast2700.h) - configs/evb-ast2700_defconfig and include/configs/evb_ast2700.h for the AST2700 EVB board The defconfig depends on ast2700-evb.dts, which is introduced in a subsequent patch; this commit must be applied with the remaining series for evb-ast2700_defconfig to build.

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"' I failed to notice that b4 noticed it was based on next and so took that as the base commit and merged that part of next to master. This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35. Reported-by: Jonas Karlman Signed-off-by: Tom Rini
