Subject: mtd: spinand: Add WATCHDOG_RESET() in spinand_mtd_read/write()
X-Git-Url: http://git.dujemihanovic.xyz/%22http:/www.sics.se/static/git-logo.png?a=commitdiff_plain;h=de6f70a6329ebf3845fa9173dbd7962a15802c05;p=u-boot.git

mtd: spinand: Add WATCHDOG_RESET() in spinand_mtd_read/write()

In case of big area read/write on spi nand, watchdog timeout may occurs.
To fix that, add WATCHDOG_RESET() in spinand_mtd_read() and
spinand_mtd_write() to ensure that watchdog is reset.
