This adds support for the NXP i.MX8MP-EVK board.

The SDRAM timings are taken from U-Boot-2020.07-rc4, other information
how to initialize the board are form U-Boot as well.

The embedded DTBs are compiled by the chain of pattern rules as follows:

  %.dts -> %.dtb -> %.dtb.S -> %.dtb.o       for barebox proper
  %.dts -> %.dtb -> %.dtb.S -> %.dtb.pbl.o   for pbl

Barebox introduced {obj,pbl,lwl}-dtb-y syntax to put the intermediate
files into extra-y. The purposes of doing so were:

 [1] prevent GNU Make from deleting the intermediate files
 [2] include .*.cmd files

In contrast, Linux does not use a special syntax for embedding DTBs
into the kernel.

For example, as you see in arch/sh/boot/dts/Makefile of Linux 5.6,

   obj-y += <basename>.dtb.o

... just works.

This is because scripts/Kbuild.include specifies .SECONDARY to cater
to [1], and scripts/Makefile.build adds the intermediates to 'targets'
to deal with [2].

Barebox had already imported the same code from Linux, so you can use
obj-y instead of obj-dtb-y, like Linux.

pbl-dtb-y and lwl-dtb-y are barebox-specific cases, so I added the
%.dtb.pbl.o pattern to intermediate_targets.

Going forward, please use obj-y, pbl-y, or lwl-y.

This adds support for the Linux Automation GmbH MC-1 board built around
the Octavo Systems OSD32MP157C-512M SiP.

The device tree is based on the one in linux-stm32/stm32-next, which
will probably be merged for Linux v5.8-rc1. Instead of waiting that
long, we import it here with some stuff removed/changed, so it's usable
for both barebox and Linux, without the prerequisite patches.

The non-barebox specific parts have been moved into separate DTSIs
(arch/arm/dts/stm32mp{157c-lxa-mc1,15xx-osd32}.dtsi), so both can be
dropped after the v5.8-rc1 sync with only include path change necessary
in arch/arm/dts/stm32mp157c-lxa-mc1.dts.

The Groboards Giant Board is a ATSAMA5D27C-D1G SiP-based SBC.
The board features a 500MHz ARM Cortex-A5 and 128MB DDR2 SDRAM in the
SiP as well as a MicroSD slot on the PCB.

barebox doesn't yet support the sama5d2 SDHCI-variant, so board support
is limited to toggling the LED and interfacing with the UART, but add
this now till the rest may follow. Device tree is based on the vendor's
device-tree available at https://github.com/Groboards/giantboard-tools

The ATSAMA5D27-SOM1-EK1 is Microchip's evaluation kit for the SAMA5D2
System in Packages (SiPs). The ATSAMA5D27C-D1G-CU SIP embeds 128 MB
of DDR2 DRAM and the SoM has a PMIC, QSPI flash and a 100Mbps PHY.

barebox already supports the sama5d2 clocks, GPIO/Pinctrl, QSPI
controller and Ethernet MAC. Most notable omission is the sama5d2
variant of the SDHCI, which differs from the MCI used by previous AT91
boards, but we kernel boot over the network works, so lets add the board
now and have the SDHCI follow later.

When no PBL is used then the DTB is used in the real barebox binary. We
already have lwl-y for code which needs to be in PBL when existing and
in the real barebox binary otherwise. Do the same for the DTBs and
compile them with lwl-dtb-y.

The phyCORE-i.MX 6Solo/DualLight is available with low-cost and
full-featured phyBOARD-Mira. One crucial difference is the supported
max. ethernet speed. On the full-featured Mira it is 1000 MBit/s but on
the low-cost Mira it is only 100 MBit/s. To cover this difference two
different images are necessary for low-cost and full-featured. Thus a
low-cost variant is added for the phyCORE-i.MX 6Solo with NAND and the
phyCORE-i.MX 6 DualLight with eMMC.
