Use the variables defined in sections.h, instead of hand rolling the
same computation.

The comment above nxp_imx8mq_evk_start is no longer accurate, as there
is no trampoline in DRAM anymore. Change the comment to reflect the current
boot flow.

Mostly cosmetic changes:
- reduce scope of local variabes
- wrap comment to fir 80 char limit
- check return value from imx8_esdhc_load_piggy
- drop intermediate function that only wraps a single other function

Useful if we need to remove a deivce from the Barebox internal DT.

This is a prerequisite for "ARM: zii-imx8mq-dev: add DT fixups", which
I missed to send out in the series.

So far arm_early_mmu_cache_flush has only been used in preparation for
executing newly-written code. For this reason, on ARMv7 and below,
it had always invalidate the icache after the dcache flush.
We don't do this on ARM64, but sync_caches_for_execution depends on this,

While the comment is correct that currently arm_early_mmu_cache_invalidate()
is only a call to to v8_invalidate_icache_all() , which doesn't clobber x0-x2,
this starts to fall apart as soon as we do something more in this function.
Make sure to properly save/restore the parameters passed to the en
This is a resend of the 2 ARM64 early cache fixes by Ahmad. They were
not applied at the time, as there was a report of them breaking Barebox
on i.MX8M. I finally had time to look into that, the first patch by
me cleans the stage, so the cache fixes no longer break anything.
At least the icache in
From: Ahmad Fatoum
On some ARM cores, cache contents are indeterminate after a Power-On
Reset. Turning on the MMU on such cores risks interpreting random cache
lines as valid, causing hard-to-debug errors.
For this reason, we always invalidate the dcache on <= ARMv7. Let's do
likewise for ARM64.

When using the RO_DATA_SECTION macro, all the individual components
are put into the rodata section. As they now end up in the same
section there is no alignment enforced between them anymore. This
leads to unaligned start pointers when any of the components have a
