This patch change the per_clocks_enable() function used in OMAP3 code to enable peripherals clocks. Only required clock should be activated. So if the board use the uart(x) as a console we need to activate it. The Board's config should include define to enable every subsystem that the board use. For a complete list of affected peripherals, registers CM_FCLKEN_PER and CM_ICLKEN_PER should be checked. Right now the bootloader can enable and disable clocks for: uart(x) using CONFIG_SYS_NS16550 gpio bank (x) using CONFIG_OMAP3_GPIO_X with X = { 2, 3, 4, 5, 6 } i2c bus using CONFIG_DRIVER_OMAP34XX_I2C.
Not required gptimer(x) and mcbsp(x) for booting are disabled by default and are not supported by any define. Their activation need to included in the per_clocks_enable if the peripheral is included. Not booting board should enable the peripheral clock connected to their driver
