board: nxp: vid: introduce PMBus framework support

2026-07-13T01:16:58Z

Wire board/nxp/common/vid.c into the framework so the legacy NXP AVS path stops carrying its own duplicate copy of the PMBus protocol and instead consumes the shared constants, decoders, and transport helpers. vid.c is the legacy NXP AVS/pre-kernel voltage-trim path for lx2160 CPUs. It does PMBus to whichever core-rail voltage monitor the board carries: LTC3882 or ISL68233 are selected with CONFIG_VOL_MONITOR_LTC3882_*/CONFIG_VOL_MONITOR_ISL68233_*. Before this change the file kept its own local PMBUS_CMD_* command-code defines, its own inline LINEAR16 mantissa/exponent math, and called into I2C through the I2C_READ/I2C_WRITE NXP wrappers in board/nxp/common/i2c_common.{c,h} which is a parallel implementation of exactly what + lib/pmbus.c provides. The intent is to make vid.c an consumer of the new PMBus. Compatibility with the former support: - CLI unchanged: vdd_override and vdd_read keep their existing semantics, return codes, and diagnostic output. - I2C transport unchanged on the wire: the framework's pmbus_* helpers call dm_i2c_read/dm_i2c_write: the same DM I2C backing that vid.c's former I2C_READ/I2C_WRITE macros already routed through on DM_I2C. - Numeric decode is bit-equivalent: pmbus_reg2data_linear16() and pmbus_data2reg_linear16() implement the PMBus 1.3 Part II mantissa/exponent.

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.

imx95/952/94_evk/: enable booting Image.gz

imx93_evk/qsb/frdm: 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. While at here, set ip_dyn to yes to allow dhcp work properly. Signed-off-by: Peng Fan

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.

imx8mp_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 (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. 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.

mx6sabre: Move environment variables to .env files

2026-06-26T20:08:26Z

Move the shared environment from CFG_EXTRA_ENV_SETTINGS in mx6sabre_common.h to a common text environment fragment in include/env/nxp/mx6sabre_common.env. The mx6sabresd and mx6sabreauto board environments include this fragment and add their own console setting, which is the only board specific difference between them. The eMMC firmware update variables remain guarded by CONFIG_SUPPORT_EMMC_BOOT inside the fragment. The now unused CONSOLE_DEV defines and the linux/stringify.h include are dropped. The generated default environment is unchanged for both boards. This was verified by comparing the output of scripts/get_default_envs.sh before and after the change, which produced identical results.

mx6ullevk: Move environment variables to .env file

2026-06-26T20:08:26Z

Move the board environment from CFG_EXTRA_ENV_SETTINGS in the config header to board/nxp/mx6ullevk/mx6ullevk.env for better maintainability. The file is named after CONFIG_SYS_BOARD so it is selected automatically without setting CONFIG_ENV_SOURCE_FILE. Drop the now unused linux/stringify.h include. The generated default environment is unchanged. This was verified by comparing the output of scripts/get_default_envs.sh before and after the change, which produced identical results.
