ARM: OMAP2+: Require proper GPMC timings for devices (9995772a) · Commits · 戴 / test

Now that we have timings in the .dts files for smc91x and 8250, we can remove the device specific checks and just print out the bootloader timings for devices that may not have timings in the .dts files. Acked-by:
