Lets overcome this limitation by introducing omap specific global
gpmc_cs0_flash holding detected flash type. Single U-Boot and SPL
binary is now running on all variants of IGEPv2 board. Modified
patches previously sent as RFC are following this mail, but as they
are based ot top of other fixes and cleanups I sent earlier they
probably won't apply until someone takes some action (yes, NACK
is also an action ;-))
