[Senthil] I have 2 options to make this check. I am now evaluating
the OMAP_HAS_FEATURE patch from Nishant to see if it could be used
to extend for VRFB before I send this patch.
Option 1:
In omapfb-main.c - in omapfb_probe()
/* Patches required on top of Nishant Menon's HAS_FEATURE */
if (def_vrfb && !OMAP_HAS_FEATURE(VRFB)) {
def_vrfb = 0;
printk(warning);
}
And OMAP_HAS_FEATURE(VRFB) in id.c
Option 2:
/*TODO : Replace cpu check with OMAP_HAS_FEATURE */
if ( def_vrfb && ! (cpu_is_omap24xx || cpu_is_omap34xx) ) {
def_vrfb = 0;
printk(warning);
}
Regards,
Senthil
