images: pbl: verify CONFIG_BAREBOX_MAX_IMAGE_SIZE is not exceeded ...

For platforms such as the at91, the boot ROM imposes an upper limit
on barebox file size.  Prior to 5a1a5ed253 ("ARM: images: use piggydata"),
BAREBOX_MAX_PBLX_SIZE seems to have been the way to go for limiting
the size of the final barebox binary when using the PBL.
With pblx removed, this variable is of no use, so have the existing
BAREBOX_MAX_IMAGE_SIZE replace its functionality.

Currently BAREBOX_MAX_IMAGE_SIZE is only checked against in the non-PBL
case, so add a check in the PBL case as well.

Revert "images: Drop unnecessary fix_size" ...

This reverts commit 5c0e165.

The fix_size scripts is not necessary for newer ARM toolchains,
it is however necessary for the older ARM toolchains (gcc-5 and older).

The original reason to drop fix_size was that it doesn't work on MIPS.
With this patch we add the -i flag so that we ignore unknown images
and can succesfully build MIPS images.

MIPS: ath79: add spi and sram bootstrap helpers ...

At least some ath79 SoC have build in 32K RAM. It allow us to use
lowlevel portion of barebox to bootstrap the system by using JTAG
debugger (For example OpenOCD).
Since ath79 has no reliable way to stop the CPU execution before
reading SPI Flash, this can cause different issues. To avoid it, we
need to flash a execution trap with software debug breakpoint to the
flash.

The workflow should be as follow:
- After power on or reset the CPU will start execution of SPI flash.
  As soon as software debug breakpoint is executed, CPU will halt and
  notify OpenOCD about breakpoint event.
- OpenOCD will load reduced barebox to SRAM and execute it.
  This part will do all needed low level initialization - PLL, RAM and
  trigger second breakpoint event.
- OpenOCD will load full barebox version to the main RAM and start
  execution.

It can be used for bring-up, so no regular flashing is needed.

kbuild: add .SECONDARY special target ...

Based on the following Linux commits:

 - 54a702f70589 ("kbuild: mark $(targets) as .SECONDARY and remove
   .PRECIOUS markers")

 - 8e9b61b293d9 ("kbuild: move .SECONDARY special target to
   Kbuild.include")

This consolidates those two commits and adjusts commit log for barebox.

GNU Make automatically deletes intermediate files that are updated
in a chain of pattern rules.

Example 1) %.dtb.o <- %.dtb.S <- %.dtb <- %.dts
Example 2) %.o <- %.c <- %.c_shipped

arch/arm/crypto/Makefile marks such targets as .PRECIOUS to prevent Make
from deleting them, but the correct way is to use .SECONDARY.

  .SECONDARY
    Prerequisites of this special target are treated as intermediate
    files but are never automatically deleted.

  .PRECIOUS
    When make is interrupted during execution, it may delete the target
    file it is updating if the file was modified since make started.
    If you mark the file as precious, make will never delete the file
    if interrupted.

Both can avoid deletion of intermediate files, but the difference is
the behavior when Make is interrupted; .SECONDARY deletes the target,
but .PRECIOUS does not.

The use of .PRECIOUS is relatively rare since we do not want to keep
partially constructed (possibly corrupted) targets.

.SECONDARY with no prerequisites causes all targets to be treated as
secondary. This agrees the policy of Kbuild.

scripts/Kbuild.include seems a suitable place to add it because it is
included from almost all sub-makes.

I deleted 'SECONDARY' (no dot) from images/Makefile, which I guess
a typo.

piggy.o would be build for every time barebox was built

Add support for the Xilinx Zynq Ultrascale+ MPSoC architecture (ZynqMP)

Barebox is booted as BL33 in EL-1 and expects that a BL2 (i.e. the FSBL)
already took care of initializing the RAM. Also for debug_ll, the UART
is expected to be already setup correctly. Thus, you have to add the
Barebox binary to a boot image as described in "Chapter 11: Boot and
Configuration" of "Zynq Ultrascale+ Device Technical Reference Manual".

ARM: phytec-som-imx6: Add full featured phyCORE-i.MX 6ULL ...

The phyCORE-i.MX 6ULL now comes in a full featured (Y2 variant) and a
low cost (Y0 variant) version. The main difference for the barebox is
the missing second USB OTG port on the Y0 variant and the RAM configuration.

So to account for these differences the existing low cost version is
renamed and the full featured version added.

The results are following phyCORE-i.MX 6ULL modules:

phyCORE-i.MX 6ULL low cost:
	- i.MX 6ULL Y0
	- 256 MB RAM
	- NAND
	- Ethernet 10/100 MBits

ARM: images: use piggydata ...

The way we assemble the multi images on ARM is rather complicated and
error prone. We currently cat the compressed barebox image behind the
PBL executable and need some magic to obtain the size of the payload and
also have to do tricks to reliably get a pointer to the compressed
image.

This patch switches over to compile the compressed payload into the PBL
image itself which has proven to work for the single PBL case and for
the ARM Linux Kernel aswell.

The goal is to unify the single PBL and the multi PBL cases together in
the future to get an easier startup path for ARM.

This patch has been tested on the i.MX53 QSB, i.MX53 Vincell, Beaglebone
black (both MLO and 2nd stage) and a Phytec phyFLEX i.MX6 board.

SoCFPGA Arria10 has also be changed slightly with this patch. We used to
generate a single image (barebox-socfpga-achilles.img) which was
used as xload image and full image. We now instead generate two images:
barebox-socfpga-achilles-xload.img and barebox-socfpga-achilles.img, the
former loaded by the ROM and the latter loaded by the xload image.
