Subject: [U-Boot] [v2 PATCH 09/12] spl, mtd, nand, atmel_nand: invert device ready pin logic
Date: Thu, 30 Oct 2014 09:15:03 +0100	[thread overview]
Message-ID: <1414656906-16632-10-git-send-email-hs@denx.de> (raw)
In-Reply-To: <1414656906-16632-1-git-send-email-hs@denx.de>

device ready pin is signalling that the device is ready on state 1
not on 0. Simmiliar as it is in drivers/mtd/nand/nand_spl_simple.c

Signed-off-by: Heiko Schocher <hs@denx.de>
