From 85b6110155cab6b67c9072c19f21dcb620c2819d Mon Sep 17 00:00:00 2001 From: Cheng Ming Lin Date: Fri, 10 Apr 2026 17:10:39 +0800 Subject: mtd: spi-nor: macronix: Document support for additional flash aliases Several Macronix SPI NOR flash devices share the same ID. For instance, the MX25L51245G and MX25L51273G share the same ID (0xc2201a) with the currently listed MX66L51235F. Add these equivalent part numbers to the comments above their corresponding flash_info entries. While this change does not affect the functional driver logic, it significantly improves the searchability of the kernel source tree. This helps users easily verify that their specific physical part is fully supported, preventing confusion and deterring redundant patch submissions that attempt to add duplicate entries for these alias parts.
