Subject: [U-Boot] [PATCH V2 08/11] mtd: nand: supress 'unknown NAND' warning if no nand is found
Date: Thu, 02 Sep 2010 08:33:31 -0700 [thread overview]
Message-ID: <1283441611.2011.113.camel@quadra> (raw)
In-Reply-To: <20100901125550.4bea5be9@schlenkerla.am.freescale.net>
This printk was added recently and results in ugly output on systems
with no NAND:
NAND: nand_get_flash_type: unknown NAND device: Manufacturer ID: 0x00, Chip ID: 0x00 0 MiB
instead of:
NAND: 0 MiB
