Merge patch series "arm: aspeed: add initial AST2700 SoC support"

2026-06-29T21:29:56Z

Ryan Chen says: AST2700 is the 8th generation of Integrated Remote Management Processor introduced by ASPEED Technology Inc. It is a Board Management Controller (BMC) SoC family with a dual-die architecture: SoC0 ("CPU" die with four ARM Cortex-A35 application cores) and SoC1 ("IO" die with peripherals) each SoC have its own SCU PLLs, clock dividers and reset domains.

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

ram: renesas: dbsc5: Add Renesas R-Car Gen5 DBSC5 driver

2026-06-16T03:38:25Z

Add Renesas R-Car Gen5 DBSC5 DRAM controller driver. This driver is currently capable of bringing LPDDR5X DRAM on Renesas R-Car X5H Ironhide board. Further boards can be supported by supplying board specific DRAM configuration data via dbsc5_get_board_data(). The driver reuses parts of previous DBSC5 driver, but due to hardware changes, can not be fully integrated into existing DBSC and DRAM driver, therefore the currentl DBSC and DRAM drivers are moved into R8A779G0 V4H specific files, and the R8A78000 X5H files are added in parallel. The Gen5 DBSC driver is meant to be used in RSIP context, while the Gen4 DBSC driver is meant to be used in SPL, therefore the Kconfig conditionals have been adjusted to match.

ram: renesas: rtvram: Add support for Renesas R-Car Gen5

2026-06-16T03:38:25Z

Add support for Renesas R-Car Gen5 R8A78000 SoC into RT-VRAM initialization driver. The changes are only a slight adjustment to the register programming, therefore reuse the existing RT-VRAM driver and parametrize those changes using driver data. Signed-off-by: Marek Vasut

ram: aspeed: Use dev_read_addr_x() API

2026-06-09T20:53:34Z

Use dev_read_addr_ptr() and dev_read_addr_index_ptr() which support both live device tree and flat DT backends, avoiding direct dependency on devfdt_* helpers. While at here, also use ofnode_read_s32_default() to replace fdtdec_get_int(). No functional changes. Signed-off-by: Peng Fan

treewide: Clean up DECLARE_GLOBAL_DATA_PTR usage

2026-02-17T19:50:22Z

Remove DECLARE_GLOBAL_DATA_PTR from files where gd is not used, and drop the unnecessary inclusion of asm/global_data.h. Headers should be included directly by the files that need them, rather than indirectly via global_data.h.
