[Ghorai] I was trying this and no success, as nand_init() get called before  subsys_initcall(gpmc_init);

126 MACHINE_START(OMAP_ZOOM3, "OMAP Zoom3 board") 
..
130         .init_irq       = omap_zoom_init_irq,
131         .init_machine   = omap_zoom_init,
..

Step-(n):
	kernel_init() -> customize_machine() 
             -> omap_zoom_init() -> gpmc_nand_init() -> which call gpmc
                functions, that's crashing, as gpmc is not initialized.

Step-(n+1):
	Followed by subsys_initcall(gpmc_init)

So I will incorporate the other input and will re-submit.
