I compare u-boot code with NES u-boot,
some file are differenced but they are fix to compile error for new compiler.
but only 1 file has clearly changed.
This is axp power IC setting.
BOOT_POWER22_DCDC_FREQSET value is below.
default value is 0x08 ,but clear lower 4bit and set to 0x00
I don't know why change setting now.
BOOT_POWER22_DCDC_MODESET value is below.
default value is 0x80 and change to 0x86.
It means DCDC1,DCDC2,DCDC3 to fixed PWM mode.
I don't know why setting just now.
