Subject: [PATCH v2 1/1] drivers: mtd: spi-nor: update read capabilities for w25q64 and s25fl064k
Date: Fri, 29 May 2020 12:46:55 +0530 [thread overview]
Message-ID: <20200529071655.739-1-rayagonda.kokatanur@broadcom.com> (raw)
Both w25q64 and s25fl064k nor flash support QUAD and DUAL read
command, hence update the same in flash_info table.
This is tested on Broadcom Stingray SoC (bcm958742t).
