Similar to TI81XX device, AM335X is treated as OMAP3 variant, where the cpu class is considered as OMAP34XX and the type is AM335X. This means, cpu_is_omap34xx(), cpu_is_ti81xx() and cpu_is_am335x() checks return success on AM335X. The TI81XX kernel config option CONFIG_SOC_OMAPTI8XX is used to include support for AM335X build.
