Subject: [PATCH] mtd: spi-nor: issi: Add support for ISSI IS25LP512MG
Date: Sun, 8 Nov 2026 00:45:16 +0000 [thread overview]
Message-ID: <20261108004516.896887-1-mparker@arista.com> (raw)
Add support for the ISSI IS25LP512MG 512Mbit (64 MiB) SPI NOR flash.
The device provides JESD216B SFDP tables which accurately describe
fast-read modes and erase geometry. Flash read, write, and erase
operations across the full 64 MiB array have been verified on hardware.
