From 22bfe94528d7ec83099922faefad0e2d1effedd0 Mon Sep 17 00:00:00 2001 From: Tudor Ambarus Date: Tue, 7 Dec 2021 16:02:54 +0200 Subject: [PATCH] mtd: spi-nor: issi: is25lp256: Init flash based on SFDP Get rid of the static initialization of the flash parameters and init them when parsing SFDP. Generated a 256 Kbyte random data and did an erase, write, read back and compare test. The flash uses for reads SPINOR_OP_READ_1_4_4_4B 0xec, for erases SPINOR_OP_BE_4K_4B 0x21, and for writes SPINOR_OP_PP_4B 0x12.
