Subject: [PATCH v5 14/14] mtd: spi-nor: issi: is25lp256: Init flash based on SFDP
Date: Fri, 3 Dec 2021 16:22:56 +0200 [thread overview]
Message-ID: <20211203142256.47370-15-tudor.ambarus@microchip.com> (raw)
In-Reply-To: <20211203142256.47370-1-tudor.ambarus@microchip.com>
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.
