ARM: i.MX: xload-esdhc: Allow placing image to align its entry point ...

Allow placing image to align its entry point with a particular entry
point address. This is needed for SoC's like i.MX8M where
vendor-provided ARM Trusted Firmware blob will exit at specific
pre-determined address and we need to be able to pick execution up
from there.

<mach/imx-header.h>. Also, while at it, define a simple inline
function to test if an arbitrary binary blob is i.MX flash header v2.

ARM: i.MX: fimware: Add pre-built BL31 ATF blob ...

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: 6b02b82
 - defconig: freescale_imx8mqevk_defconfig

The resulting file of interest is output/images/bl31.bin

ARM: Add code to support SMCCC on AArch64 ...

Port SMCCC code from Linux kernel. To accomodate that:

  - Introduce CONFIG_ARM_SMCCC, to allow enabling the code
    independent of CONFIG_ARM_SECURE_MONITOR

  - Bring <linux/arm-smccc.h> in

  - Add necessary constants to arch/arm/asm-offsets.c

ARM: nxp-imx8mq-evk: Update DDR initialization code ...

Previous version of DDR initialization code was generated by a beta
version of MX8_DDR_tool. This updates the code to the output of
MX8_DDR_tool v1.0, which seem to fix the vendor Linux kernel hang*
that was happening with the previous version.

* The kernel would hang as soon as it tried to utilize DDR's DVFS
  features and switch DDR frequency (disabling busfreq-imx8mq.c would
  fix the problem).

i.MX: iomuxv3: restore NO_PAD_CTRL semantic ...

A NO_PAD_CTRL flag used to keep a pad configuration untouched.
With commit 094820a63bfd ("i.MX: iomuxv3: Use helper functions in iomux-v3.h")
the NO_PAD_CTRL semantic changed to set a pad configurations to zero, which
breaks non-DT boards, where NO_PAD_CTRL is freqently used to keep a boot-up
default pad configuration, which often is non zero.

Restore the old semantic, dont write PAD_CTRL when NO_PAD_CTRL is set.

scripts: imx-image: fix build with OpenSSL 1.1.x ...

OpenSSL 1.1.x made some of the types opaque, so peeking inside directly
doesn't work anymore. Use the correct accessors instead.

I've dropped the algorithm check, as EVP_PKEY_get0_RSA() already verifies
that the pubkey is RSA and returns NULL if it isn't.

cmdlinepart: Allow empty string ...

Currently when cmdlinepart_do_parse() is called with an empty
partitions string then an unnamed partition with size 0 is created.
This is wrong of course and instead no partition should be
created.

With this barebox no longer crashes while booting when all partitions
are deleted on the commandline using "nand0.partitions="
