1. Use the modified 'uImage' directly
 a. Update 'uImage' to myd-am335x and run the kernel;
 b. After the kernel start up, insmod the adc driver "am335x_adcdrv.ko":
    # insmod am335x_adcdrv.ko
 c. After the driver installed, you can read the adc in userspace by reading files:
    /sys/class/am335x_adc/chanX (X=0,1,3,4,5,6,7 for different ADC channel)

2. Apply the patch "myd-am335x-add-adc-remove-tsadc-20140613.patch" and compile uImage from source
 a. Copy "myd-am335x-add-adc-remove-tsadc-20140613.patch" to the kernel root DIR, and apply the patch by following command:
    $ make distclean
    $ patch -p0 < myd-am335x-add-adc-remove-tsadc-20140613.patch
    $ make myd_am335x_defconfig
    $ make uImage
 b. After completion, update the new uImage to myd-am335x and run the kernel;
 c. After the kernel start up, insmod the adc driver "am335x_adcdrv.ko":
    # insmod am335x_adcdrv.ko
 d. After the driver installed, you can read the adc in userspace by reading files:
    /sys/class/am335x_adc/chanX (X=0,1,3,4,5,6,7 for different ADC channel)

NOTE: If using this general ADC driver, you can't use adc touch panel anymore.
