Subject: [PATCH v3 09/10] dt-bindings: mtd: partitions: Convert brcm,trx to DT schema
Date: Wed, 21 Jan 2026 13:56:42 -0600	[thread overview]
Message-ID: <20260121-dt-mtd-partitions-v3-9-ec3af93c8f93@kernel.org> (raw)
In-Reply-To: <20260121-dt-mtd-partitions-v3-0-ec3af93c8f93@kernel.org>

Convert the brcm,trx partition binding to DT schema format.

As the "linksys,ns-firmware" compatible also uses "brcm,trx" as a
fallback, move it to the converted binding.

-Broadcom TRX Container Partition
-================================
-
-TRX is Broadcom's official firmware format for the BCM947xx boards. It's used by
-most of the vendors building devices based on Broadcom's BCM47xx SoCs and is
-supported by the CFE bootloader.
-
-Design of the TRX format is very minimalistic. Its header contains
-identification fields, CRC32 checksum and the locations of embedded partitions.
-Its purpose is to store a few partitions in a format that can be distributed as
-a standalone file and written in a flash memory.
-
-Container can hold up to 4 partitions. The first partition has to contain a
-device executable binary (e.g. a kernel) as it's what the CFE bootloader starts
-executing. Other partitions can be used for operating system purposes. This is
-useful for systems that keep kernel and rootfs separated.
-
-TRX doesn't enforce any strict partition boundaries or size limits. All
-partitions have to be less than the 4GiB max size limit.
-
-There are two existing/known TRX variants:
-1) v1 which contains 3 partitions
-2) v2 which contains 4 partitions
-
-There aren't separated compatible bindings for them as version can be trivialy
-detected by a software parsing TRX header.
-
-Required properties:
-- compatible : (required) must be "brcm,trx"
-
-Optional properties:
-
-- brcm,trx-magic: TRX magic, if it is different from the default magic
-		  0x30524448 as a u32.
-
-Example:
-
-flash@0 {
-	partitions {
-		compatible = "brcm,trx";
-	};
-};
