[PATCH 00/21] FlexSPI image/boot/update support

[Marco Felsch]

Hi,

by this serie the missing FlexSPI/QSPI boot support is added. The
FlexSPI boot option is available on i.MX8MM/N/P SoCs.

The integration is done by using the single-image approach, so no
special QSPI image is required. The same image which can be used for
eMMC/eMMC-boot, SD, USB, chainload now supports QSPI. This is done by
adding a 2nd IVT header on the appropriate place and adding a QSPI
update handler.

Patch1-4: General fixes
Patch7-onward: Add the FlexSPI/QSPI support
