* U-Boot running on top of UEFI.

3707c6ee0d log: Add a way to log error-return values
When functions return an error it propagates up the stack to the point
where it is reported. Often the error code provides enough information
about the root cause of the error that this is obvious what went wrong.

However in some cases the error may be hard to trace. For example if a
driver uses several devices to perform an operation, it may not be
obvious which one failed.

Add a log_ret() macro to help with this. This can be used to wrap any
error-return value. The logging system will then output a log record when
the original error is generated, making it easy to trace the call stack
of the error.

This macro can significantly impact code size, so its use is controlled
by a Kconfig option, which is enabled for sandbox.

bf802f5d54 power: extend prefix match to regulator-name property
This patch extends pmic_bind_children prefix matching. In addition to
the node name the property regulator-name is used while trying to match
prefixes. This allows assigning different drivers to regulator nodes
named regulator@1 and regulator@10 for example.
I have discarded the idea of using other properties then regulator-name
as I do not see any benefit in using property compatible or even
regulator-compatible. Of course I am open to change this if there are
good reasons to do so.

The reset circuitry in the RK3399 only resets 'almost all logic' when

trigger a power-on reset via a GPIO trigger.

This adds the necessary support to the rk3399-puma (i.e. RK3399-Q7)
board-support and the documentation for the new property
(sysreset-gpio) within the /config-node.

4d9253fb76 rockchip: rk3188: use boot0 hook to load up SPL in 2 steps
For the RK3188, the BROM will attempt to load up the first stage
image (SPL for the RK3188) in two steps: first 1KB to offset 0x800
in the SRAM and then the remainder to offset 0xc00 in the SRAM.
It always enters at 0x804, though.

With this changeset, the RK3188 boot removes the TPL (stub) stage and
builds a single SPL binary that utilizes the early back-to-bootrom via
the boot0-hook.

Consequently, the passing of the saved boot params via pmu->os_reg[2]
is also removed.
