Subject: [U-Boot] [PATCH 2/5] NAND: Add nand read.raw and write.raw commands
Date: Thu,  8 Sep 2011 22:39:37 +0200	[thread overview]
Message-ID: <1315514380-19089-3-git-send-email-marek.vasut@gmail.com> (raw)
In-Reply-To: <1315514380-19089-1-git-send-email-marek.vasut@gmail.com>

These commands should work around various "hardware" ECC and BCH methods.
