While infrastructure for installing OP-TEE was already there, no
upstream boards made use of it. Let's have OP-TEE installation happen in
generic code, so it may be enabled for any upstream board.

Commit 663894d99c64 ("firmware: refactor firmware/Makefile") aligned the
barebox code with the kernel code. This commit replaced the usage of
$(fw-external-y) by $(obj-pbl-y) and added the '.gen.o' suffix directly
but didn't adapted the patsubst logic for tracking the binary firmware
files. As result a firmware binary file update is not recognized by make
and and won't make into the final binary. This commit fixes this and so
an update will be recognized automatically without require a 'make
clean' before.

Normally, barebox embds firmware into the binary referencing it, which
means that device tree blobs, RAM training code and e.g. TF-A for i.MX8M
end up in the prebootloader, while, e.g. Freescale FMan microcode ends
up in barebox proper. The only exception so far was barebox proper:
When only the PBL fits in on-chip SRAM, barebox proper is chainloaded
from the boot medium. To avoid TOCTOU attack, it's read fully into DRAM
after setup and then a SHA256 is calculated and compared against the
hash embedded in barebox PBL, which in a secure boot system would be
trusted by virtue of the PBL as a whole being verified beforehand by
the BootROM.
Reuse this mechanism to support arbitrary firmware, which is now termed
external firmware. Such firmware is placed beyond the piggydata (barebox
proper) and only offset and hash are included in the prebootloader
image. The new get_builtin_firmware_ext() is used to retrieve this
external firmware after integrity verification with SHA256.
This enables referencing firmware blobs from PBL that would bloat the
size of the PBL beyond what can fit into on-chip SRAM, e.g. very big
OP-TEE binaries. As users of get_builtin_firmware() didn't have to worry
about TOCTOU so far, we panic when a firmware verification fails to
ensure that we never load an OP-TEE that has been modified in-transit
We can't include the OP-TEE binary in barebox proper, because we need
to install it in EL3, but barebox proper on the i.MX8M runs as BL33
in a lower exception level.

There are DDR3L, DDR4 and LPDDR4 variants of the i.MX8M* SoMs used with
the NXP EVKs. So far, we only supported LPDDR4. For DDR4, we just need
different PHY training code. Encode the DRAM variant information
into a new dram_timing_info::dram_type and adjust the driver to make use
of it. The new CONFIG_FIRMWARE_IMX_DDR4_PMU_TRAIN Kconfig symbol can
co-exist with CONFIG_FIRMWARE_IMX_LPDDR4_PMU_TRAIN, allowing the same
barebox binary to target different memory types, provided board code
can determine what kind of DRAM is fitted.

The prologue of the build system is not specific to Linux or Barebox.
Paritially resync with Linux 5.7-rc4
- In Linux, $(objtree) is always '.', and $(srctree) might be relative.
I am keeping both absolute for now to avoid unexpected breakage.
- I did not resync single target for now. We need to touch
Makefile.build a lot if we want to resync it.
- 'export CDPATH=' is Barebox-only code, which was added by
commit 6cc8d0544658 ("Makefile: disable CDPATH"). Keep it.
- KBUILD_SRC no longer exists in the upstream Linux. I replaced it
with building_out_of_srctree.
- scripts/mkmakefile does not contain anything specific to Linux or
Barebox. Resync it with Linux 5.7-rc4
- scripts/tags was imported from Linux 3.6 with some cherry-picks on
top of that. Resync it with Linux 5.7-rc4

The "Primary Protected Application" (PPA) is a PSCI compliant firmware
distributed by NXP. It is needed to start the secondary cores on
Layerscape SoCs. Without it Linux will be started in EL3 and doesn't
work properly. The precompiled firmware images can be found on
https://github.com/NXP/qoriq-ppa-binary and are not included in
barebox.

This adds ethernet support for the Freecale Layerscape SoCs. The
architecture in these SoCs is called "Data Path Acceleration
Architecture" (DPAA). It is comprised of:
- The Queue Manager (QMan)
- Buffer Manager (BMan)
- Frame Manager (FMan)
- Multirate Ethernet Media Access Controller (mEMAC)
The code is based on the corresponding U-Boot driver enriched with
device tree parsing and proper device driver support.
Tested on LS1046a, should work on other SoCs aswell with some minor
quirks. SerDes support has been removed for now.

Building additional firmware into the boot image has some license

note about this.

The prebuilt ATF binary is in fact a license compliance issue. While
the used BSD-3-clause license allows aggregation with the Barebox
binary, the chosen license requires us to ship the license text
itself for the source distribution and also for the binary form if
the built boot image contains the ATF binary.
As this is a restriction that only applies to some boot images,
depending on the Barebox configuration, it's non-trivial to do
proper license compliance from within the Barebox source.
Remove the prebuilt binary and rely on the external build system
or user to provide the correct binary. Most system build systems
already provide a proper way to handle the license dependency
issue.

Running Linux on i.MX8M requires us to use and properly set up a ARM
Trusted Firmware blob. For the sake of convenience, add a pre-built
blob to our firmware tree, so it can be used by individual boards.
This blob was built using Buildroot:
- commit: 6b02b8210acb18773f2c4b26cfc11d1f9bc4fb88
- defconig: freescale_imx8mqevk_defconfig
