Subject: [PATCH 0/3] mtd: spi-nor: Extend SFDP to support additional octal modes as per latest JEDEC standard
Date: Thu, 1 Dec 2022 13:15:29 -0500 [thread overview]
Message-ID: <20221201181532.255449-1-nathan.morrison@timesys.com> (raw)
In the latest JEDEC standard (JESD216F), there are now bitfields in the
4 byte address instruction table for 1S-1S-8S and 1S-8S-8S modes
This patchset adds support for checking the 4BAIT for these modes,
along with additional NO_SFDP_FLAGS to support enabling these new modes
Nathan Barrett-Morrison (3):
mtd: spi-nor: Extend SFDP 4byte address instruction lookup table with
new octal modes as per JEDEC JESD216F
mtd: spi-nor: Add additional octal-mode flags to be checked during
SFDP
mtd: spi-nor: Add support for IS25LX256 operating in 1S-1S-8S mode
