This patch (still) doesn't know about the mx25l3205d, mx25l12805d and mx25l12855e devices.
I randomly did this:
-> { "mx25l3205d", INFO(0xc22016, 0, 64 * 1024, 64, 256, 3, 0) }, -> { "mx25l6405d", INFO(0xc22017, 0, 64 * 1024, 128, 256, 3, 0) }, { "mx25l12805d", INFO(0xc22018, 0, 64 * 1024, 256, 256, 3, 0) }, -> { "mx25l12855e", INFO(0xc22618, 0, 64 * 1024, 256, 256, 3, 0) },
