From: Masahiro Yamada Date: Fri, 15 Sep 2017 12:44:58 +0000 (+0900) Subject: mtd: nand: do not check R/B# for CMD_READID in nand_command(_lp) X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=6f29c7a8f1fa8abef167d9017947cf090e39d60e;p=u-boot.git mtd: nand: do not check R/B# for CMD_READID in nand_command(_lp) Read ID (0x90) command does not toggle the R/B# pin. Without this patch, NAND_CMD_READID falls into the default: label, then R/B# is checked by chip->dev_ready().
