Describe the 2 GiB DRAM configuration, AXP803 PMIC, essential supplies, microSD, UART, battery monitoring and USB peripheral port. Leave eMMC and unverified peripherals disabled. Include CPU operating points for frequency scaling and thermal cooling. Enable the PMIC USB supply and connect it to the PHY for VBUS detection. Keep the ALDO2 VCC-PL and ALDO3 VCC-PLL/AVCC supplies enabled, matching the stock firmware and the measured 1.8 V and 3.0 V baseline settings. Tested with kexec into Linux 7.3.0-rc1 without regulator_ignore_unused: CPU frequency transitions, CPU cooling frequency cap, and USB supply unplug/replug detection with SSH reconnection. Cold-boot validation of this revision remains pending.
