/*
* Power Tree
*
* In general an attempt is made to include all rails called out by
* the schematic as long as those rails interact in some way with
* the AP. AKA:
* - Rails that only connect to the EC (or devices that the EC talks to)
* are not included.
* - Rails _are_ included if the rails go to the AP even if the AP
* doesn't currently care about them / they are always on. The idea
* here is that it makes it easier to map to the schematic or extend
* later.
*
* If two rails are substantially the same from the AP's point of
* view, though, we won't create a full fixed regulator. We'll just
* put the child rail as an alias of the parent rail. Sometimes rails
* look the same to the AP because one of these is true:
* - The EC controls the enable and the EC always enables a rail as
* long as the AP is running.
* - The rails are actually connected to each other by a jumper and
* the distinction is just there to add clarity/flexibility to the
* schematic.

U-Boot on Rockchip
==================
There are several repositories available with versions of U-Boot that support
many Rockchip devices [1] [2].
The current mainline support is experimental only and is not useful for
anything. It should provide a base on which to build.
So far only support for the RK3288 and RK3036 is provided.
A wide range of Rockchip SoCs are supported in mainline U-Boot

This converts the SPL image to the required SPI format by adding the Rockchip
header and skipping every 2KB block. Then the U-Boot image is written at
header and skipping every second 2KB block. Then the U-Boot image is written at
offset 128KB and the whole image is padded to 4MB which is the SPI flash size.
