ARM: i.MX: rebuild .imximg if DCD table in .imxcfg changes ...

So far changing the DCD table didn't trigger a rerun of the i.MX
image utility. To fix this, we need to have the DCD table as prerequisite
to the .imximg rule. The file name is contained in $(CFG_$(@F)), but
can't be used directly because $@ (and by extension @F) has no value
when first expanded in the read-in phase. If we expand a second time
during the target-update phase however, we would get the correct value.

GNU make provides .SECONDEXPANSION to expand all following prerequisites
a second time. Use it to have changes to the DCD table rebuild the
image.

Because we are now using imx_image_rule to generate the target, we must
escape each $ one more time to arrive at $$$$(CFG_$$$$(@F)).

In the final step, we replace $$$$(@F) with %.imximg, so we support the
rules not ending in .imximg as well.

Dependency file generation is still broken however and changed to headers
included in DCD tables won't be caught, but this functionality can be
fixed in a separate patch.

ARM: i.MX: introduce imx_image_rule variable for code deduplication ...

The next patch will add the .imxcfg file as a rule prerequisite, so the
target is rebuilt if it changes. Instead of duplicating it in all rules,
factor out the common parts into a imx_image_rule variable.

As the arguments are now going through an eval, any use of $ must be
escaped with another $ to become $$.

No functional change.

images: i.MX: rearrange image rules in preparation for boilerplate removal ...

The following commit will introduce a variable define to remove the
duplication in the different [supe]*imximg rules.

Prepare for this by rearranging the command line flags to line up with
the letters in the extension (i.e. -e -s for esimximg instead of -s -e)
and by splitting off a multi-target rule into two.

The former improves readability when the define is introduced, as it is
then easy to see the correspondence between extension and arguments.

The latter is needed because we will call the variable for each target.

No functional change.

Rework the evk boot flow to use the new piggydata load function and
install a trampoline for the TF-A setup. This allows the PBL boot
process to stay in SRAM up until the verification of the piggydata is
done and main barebox can be loaded.

The trampoline loads 4 bytes right after the trampoline, we copy the
runtime offset there so the trampoline jumps back into the SRAM PBL.

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.

pbl multiimage: Allow to check image sizes ...

PBL images are often constrained in size by limitations exposed by
the SoCs SRAM size or partition sizes on the boot device. So far
we tried to configure these limits in Kconfig, but with PBL multi
images and thus different limitations for the different supported
images this no longer works. This patch has another approach for
it:

During build time make variables containing the relevant sizes for
each image are created. These are:

PBL_CODE_SIZE_$(symbol)
PBL_MEMORY_SIZE_$(symbol)
PBL_IMAGE_SIZE_$(symbol)

PBL_CODE_SIZE_$(symbol) contains the pure code size of the PBL, it
should be smaller than the available SRAM during boot. Normally the
PBL's bss segment also needs to be in the initial SRAM, for this
case PBL_MEMORY_SIZE_$(symbol) is the relevant variable.
PBL_IMAGE_SIZE_$(symbol) contains the full size of the PBL image
including the compressed payload (but without any image headers
created later by SoC specific image tools).

$(symbol) is a placeholder for the start symbol used for this PBL image,
thus for the i.MX53 QSB with entry start_imx53_loco

PBL_CODE_SIZE_start_imx53_loco

will be created. The images/Makefile.* can use these variables directly
to check sizes or specify the same variables with a "MAX_" prefix. So
when images/Makefile.imx specifies

MAX_PBL_CODE_SIZE_start_imx53_loco = 0x10000

then the build system will make sure that the PBL code for the QSB will
not get bigger than 64KiB.

Also included in this patch are the size restrictions for the i.MX8MQ
images as an example how to use this.
