[PATCH v9 0/7] nand prefetch-irq support and ecc layout chanage

[Sukumar Ghorai]

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.
