From cadd42025cf5694a391f6cedb6374117336ae2c8 Mon Sep 17 00:00:00 2001 From: Daniel Thompson Date: Mon, 4 Jun 2018 13:52:22 +0100 Subject: flashchips: Add Macronix MX25U51245G Copy 'n paste support for Macronix MX25U51245G. I don't pretend to know a whole lot about SPI FLASH so its mostly copied from other MX25U devices and double checked a few bits and pieces against the datasheet. I have tested basic probe, read, erase and write using layout files. I tested both with 4MB@0x0000000 and 64K0@0x3f00000 (the later means I have tested 4-byte addressing).
