I have searched quite enough this register but I really can't find it.
I have tried to read from 0x01c20c00 on but I see only zeros.
It seems, in order to read the REVID (Major, Minor, ...) I shouldn't need to enable any flag, as I can see in
the ARM subsytem manual.

Auxiliary Clock (AUXCLK)
The AUXCLK clock domain operates at the same clock rate as the oscillator input frequency, bypassing
both PLL controllers. The reference clock for the AUXCLK domain frequency can be 24 MHz, 36 MHz,
19.2 MHz, or 27 MHz, depending on the crystal input used. The following peripherals' clock source is
driven from the AUXCLK clock domain: ADC, RTO, Timer0-4, WDT, UART0, I2C, SPI4, and PWM0-3.
Any idea?
