Subject: [PATCH V3 1/2] dt-bindings: mtd: partitions: u-boot: allow dynamic subpartitions
Date: Tue, 18 Oct 2022 17:42:01 +0200 [thread overview]
Message-ID: <20221018154202.4634-1-zajec5@gmail.com> (raw)
From: Rafał Miłecki <rafal@milecki.pl>
U-Boot partition may contain subpartitions. For example Broadcom
includes environment data block in the middle of its U-Boot partition.
This allows describing Broadcom's U-Boot env data and will allow
referencing its NVMEM cell in the future.
Reg: 118f3fbe517f4 ("dt-bindings: mtd: partitions: support label/name only partition")
Ref: dd638202dfb65 ("dt-bindings: mtd: partitions: add additional example for qcom,smem-part")
Signed-off-by: Rafał Miłecki <rafal@milecki.pl>
