nvmem: layouts: u-boot-env: add optional "env-size" property

2025-11-24T17:06:22+00:00

Some devices reserve a larger NVMEM region for the U-Boot environment than the actual environment data length used by U-Boot itself. The CRC32 in the U-Boot header is calculated over the smaller data length, causing CRC validation to fail when Linux reads the full partition. Allow an optional device tree property "env-size" to specify the environment data size to use for CRC computation. v2: add missing $ref line to DT binding Signed-off-by: Jascha Sundaresan Reviewed-by: Rob Herring (Arm) Signed-off-by: Srinivas Kandagatla Link: https://patch.msgid.link/20251114110636.143268-5-srini@kernel.org Signed-off-by: Greg Kroah-Hartman
