Hi Tony,
As this patch is trivial can it be upstreamed ? Thanks & Regards, Hrishikesh ________________________________________ From: Bhandiwad, Hrishikesh Sent: Friday, July 29, 2011 6:13 PM To: linux-mtd@lists.infradead.org; linux-omap@vger.kernel.org; linux-kernel@vger.kernel.org Cc: Bhandiwad, Hrishikesh; Hiremath, Vaibhav; Premi, Sanjeev Subject: [PATCH v2] OMAP3: NAND: Adding NAND support and specifying NAND partitions.
This patch adds the NAND support on OMAP3EVM board and also allocates five partitions on NAND. Referred to file: arch/arm/mach-omap2/board-omap3beagle.c
