[PATCH 00/26] i.MX8M HAB Fixes

[Marco Felsch]

Hi all,

unfortunately with the addition of the FlexSPI image support I broke
the HAB support for i.MX8M devices because I didn't honored the new CSF
location. This PR will fix this for the MMC/SD/USB boot case.

Additional the PR adds the support to HAB boot the system from a QSPI
NOR as well. For the FlexSPI HAB boot a 2nd CSF slot/area is added to
keep the very user-friendly single-image approach.

Before reviewing Patch13 and onwards I do recommend to look at Patch26
first to get an overview of the final result.

Patch1-7:
Cleanup the hab command code and image artifacts and enable it support
for all i.MX8M devices.

Patch8-9:
Add the signing support to the Makefile.imx and convert the i.MX8M rules
to use the new macro to cleanup the code.

Patch10-12:
Prepare i.MX8M*-EVKs to be able to build signed images.

Patch13-14:
Add support for multiple CSF slots.

Patch15-23:
Fix the HAB support for MMC/SD card first and add/fix the HAB support
for FlexSPI images.

Patch24:
Make it possible to pass CST command line paramters via environment.
This is very useful for new CST versions which do support PKCS11
out-of-the box if the user specify the backend via '-b pkcs11'.

Patch25-26:
Documentation patches to become an overview of the FlexSPI HAB single
image implementation.

Testers are very welcome :)

Regards,
  Marco
