Subject: mtd: nand: Add WATCHDOG_RESET() in nanddev_mtd_erase()
X-Git-Url: http://git.dujemihanovic.xyz/html/%7B%7B%20.RelPermalink%20%7D%7D?a=commitdiff_plain;h=3f6cfdaa23763b691345d2d3709fe1668291f407;p=u-boot.git

mtd: nand: Add WATCHDOG_RESET() in nanddev_mtd_erase()

In case of big area erased on nand, watchdog timeout may occurs.
To fix that, add WATCHDOG_RESET() in nanddev_mtd_erase() to ensure that
watchdog is reset.
