Subject: [PATCH 0/2] handle RDCR opcode for Macronix
Date: Mon, 22 Sep 2025 17:56:31 +0200 [thread overview]
Message-ID: <20250922155635.749975-1-maarten@zanders.be> (raw)
This series introduces a configurable RDCR (Read Configuration Register)
opcode for spi-nor flashes and applies a fix for Macronix devices.
Patch 1 adds a new flash parameter to hold the RDCR opcode, defaulting
to 0x35 (JEDEC standard).
Patch 2 applies a Macronix-specific fixup, setting the RDCR opcode to
0x15.
