Patch queue for efi - 2016-11-17

Highlights this time around:

  - x86 efi_loader support
  - hello world efi test case
  - network device name is now representative
  - terminal output reports modes correctly
  - fix psci reset for ls1043/ls1046
  - fix efi_add_runtime_mmio definition for x86
  - efi_loader support for ls2080

Most new systems in U-Boot these days make use of the generic "distro"
framework which allows a user to have U-Boot scan for a bootable OS
on all available media types.

This patch extends the LS2080ARDB board to use that framework if the
hard coded NOR flash location does not contain a bootable image.

When implementing efi loader support, we can expose runtime services
for payloads. One such service is CPU reset.

This patch implements RTS CPU reset support for layerscape systems.

The efi loader code has its own memory map, so it needs to be aware where
the spin tables are located, to ensure that no code writes into those
regions.

The DP-DDR shouldn't be exposed as conventional memory to an OS, so let's
rather claim it's a reserved region in the EFI memory map

On ls2080 we have a separate network fabric component which we need to
shut down before we enter Linux (or any other OS). Along with that also
comes configuration of the fabric using a description file.

Today we always stop and configure the fabric in the boot script and
(again) exit it on device tree generation. This works ok for the normal
booti case, but with bootefi the payload we're running may still want to
access the network.

So let's add a new fsl_mc command that defers configuration and stopping
the hardware to when we actually exit U-Boot, so that we can still use
the fabric from an EFI payload.

For existing boot scripts, nothing should change with this patch.

Some boards decided not to run ATF or other secure firmware in EL3, so
they instead run U-Boot there. The uEFI spec doesn't know what EL3 is
though - it only knows about EL2 and EL1. So if we see that we're running
in EL3, let's get into EL2 to make payloads happy.

Previously, it was assumed that there is a 1:1 mapping between
PM ID defined in the platform firmware and a PM domain. However, there
can be a situation where multiple PM IDs belong to a single PM domain
(e.g. PM IDs for GPU and two pixel processors correspond to a single
PM domain).

This patch adds support for assigning more than one PM ID to
a single PM domain.

Updated documentation accordingly.

Assigned pixel processors PM IDs to GPU PM domain.
