[trini: Document name parameter in led.h]

in linux we have the option to create the name of a led
optionally through the following properties:

- function
- color
- function-enumerator

This patch adds support for parsing this properties if there
is no label property.

The led name is created in led_post_bind() and we need some
storage place for it. Currently this patch prevents to use
malloc() instead it stores the name in new member :

        char name[LED_MAX_NAME_SIZE];

of struct led_uc_plat. While at it append led tests for the
new feature.

Do some type and cast cleanup on that fpga_desc type while at it.

Add support for the R-Car S4 Starter Kit with R8A779F4 SoC support.
This implementation natively uses OF_UPSTREAM to pull in most recent
DT. The defconfig is derived from S4 Spider, with reduced UART baud
rate to 921600 Bdps. The DT alias to rswitch is removed as the alias
should point to rswitch ports, not to rswitch itself, see [1].

So far only VBE-simple is implemented in U-Boot. This supports a single
image which can be updated in situ.

It is often necessary to support two images (A and B) so that the board
is not bricked if the update is interrupted or is bad.

In some cases, a non-updatable recovery image is desirable, so that the
board can be returned to a known-good state in the event of a serious
failure.

Introduce ABrec which provides these features. It supports three
independent images and the logic to select the desired one on boot.

While we are here, fix a debug message to indicate the function it
called. Provide a maintainers entry for VBE.

Note that fwupdated only supports VBE-simple so far, but supports for
ABrec will appear in time.

When VBE operates within VPL it does not want the FDT to be changed.
Provide a way to disable this feature.

Move the FIT_IMAGE_TINY condition out of spl_fit_record_loadable() so
that both conditions are together. This makes the code easier to
understand.

Replace the existing fit_loaded member, which is no-longer used.

Add a linker symbol which can be used to mark relocation code, so it can
be collected by the linker and copied into a suitable place and executed
when needed.
