The following set of patches applies on linux-2.6.
The main motivations behind this patch series are -
1. support NAND I/O in irq mode.
2. support of different ECC schema.
3. also add support ecc layout as like in romcode ecc layout, but not enabled
v9: gpmc_init() changed to postcore_initcall(gpmc_init);
v8: free_irq() added; used timeout for while(tight loop)
And resend of http://www.mail-archive.com/linux-omap@vger.kernel.org/msg41614.html
v7: NAND type (x16 or x8) is board specific and not omap specific; this passed form board file.
http://www.mail-archive.com/linux-omap@vger.kernel.org/msg41469.html
v6: configurable transfer type from board file;
#define irq number used for nand-irq

v5: http://www.mail-archive.com/linux-omap@vger.kernel.org/msg35860.html
This address the input as to support the irq_chained in GPMC.
