ls1028ardb: Move environment variables to .env file

2026-07-06T01:58:58Z

Move the bulk of the board environment from CFG_EXTRA_ENV_SETTINGS in ls1028ardb.h to board/nxp/ls1028a/ls1028ardb.env. Because the board directory is shared with ls1028aqds, the file is selected through CONFIG_ENV_SOURCE_FILE rather than the SYS_BOARD default. The distro_bootcmd machinery cannot be expressed in a .env file. The BOOTENV macro expands to environment text with embedded NUL separators, and the board overrides three distro variables (boot_scripts, boot_a_script and scan_dev_for_boot_part) that must follow BOOTENV to take effect. BOOTENV and those three overrides therefore remain in CFG_EXTRA_ENV_SETTINGS, which is concatenated after the .env text, while every other variable moves to the .env file. The resulting default environment is functionally unchanged for both the ls1028ardb_tfa and ls1028ardb_tfa_SECURE_BOOT defconfigs. This was verified with an order aware comparison of the default environment before and after the change. The only difference is that three accidental double spaces in xspi_bootcmd, sd_bootcmd and emmc_bootcmd collapse to single spaces, because the preprocessor normalises whitespace in the now unquoted text, which does not affect command parsing.

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.

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.

imx8mm/n_evk: enable booting Image.gz and avoid extra memcpy

2026-06-27T02:02:46Z

Add support for booting compressed kernel Image.gz by defining kernel_comp_addr_r and kernel_comp_size in the default environment. Set kernel_comp_addr_r to a high memory region to provide a dedicated decompression buffer, avoiding overlap between compressed input and decompressed output. Also adjust CONFIG_SYS_LOAD_ADDR from 0x40480000 to 0x40400000. With TEXT_OFFSET=0, the kernel is relocated directly to loadaddr, so separating decompression and execution regions is required to guarantee safe decompression without additional copying.

Add support for booting compressed kernel Image.gz by defining kernel_comp_addr_r and kernel_comp_size in the default environment. Set kernel_comp_addr_r to a high memory region (0x80000000) to provide a dedicated decompression buffer, avoiding overlap between compressed input and decompressed output. Also adjust CONFIG_SYS_LOAD_ADDR from 0x40480000 to 0x40600000.
