[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.
