Subject: [PATCH] mtd: spi-nor: make s25fl129p1 skip SFDP parsing
Date: Thu, 19 Dec 2019 16:12:12 +0800	[thread overview]
Message-ID: <20191219081212.16927-1-jiwei.sun@windriver.com> (raw)

From: jsun4 <jiwei.sun@windriver.com>

The right page size of S25FL129P has been gotten in the function
spi_nor_info_init_params() before invoking spi_nor_parse_bfpt(),
it is 256-bytes, but the size will be changed to 512 bytes in the
following function spi_nor_parse_bfpt(). And there is no explanation of
the SFDP according to the datasheet of S25FL129P. So we can skip
SFDP parsing.
