Subject: [PATCH v2 34/35] mtd: spi-nor: macronix: mx25l25635e: Use SPI_NOR_PARSE_SFDP
Date: Tue, 27 Jul 2021 07:52:21 +0300 [thread overview]
Message-ID: <20210727045222.905056-35-tudor.ambarus@microchip.com> (raw)
In-Reply-To: <20210727045222.905056-1-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_1_4_4_4B
0x3e.
