First 896kB to u-boot. Enough space for SPL, u-boot and ATF.
Next 128kB to u-boot environment and rest to firmware.
Firmware partition is compatible FIT image dynamic splitting.

Subject: [PATCH] arm64: dts: allwinner: a64: olinuxino: Add bank supply
regulators
Allwinner A64 SoC has separate supplies for PC, PD, PE, PG and PL. This
patch adds regulators for them to the pinctrl node.
Exception is PL which is used by the RSB bus. To avoid circular
dependencies, VCC-PL is omitted.
On boards with eMMC, VCC-PC is supplied by ELDO1, instead of DCDC1.

There is a red LED marked as `GPIO_LED1` on the silkscreen and connected
to PE17 by default. So lets add this missing bit in the current hardware
description.

From: Jernej Skrabec <jernej.skrabec@siol.net>
Allwinner H6 PWM is similar to that in A20 except that it has additional
bus clock and reset line.
Note that first PWM channel is connected to output pin and second
channel is used internally, as a clock source to AC200 co-packaged chip.
This means that any combination of these two channels can be used and
thus it doesn't make sense to add pinctrl nodes at this point.
