Hi,
This is the v6 series to introduce i.MX8qm/qxp Display Processing Unit(DPU)

DPU is comprised of a blit engine for 2D graphics, a display controller
and a command sequencer. Outside of DPU, optional prefetch engines can
fetch data from memory prior to some DPU fetchunits of
Some syscalls can be implemented from different __NR_* variants. For
example, sys_dup2() can be implemented based on __NR_dup3 or __NR_dup2.
In this case it's useful to produce an error message when neither are
detected, mentioning the supported alternatives. In case of trouble with
includes, it
The documentation header in the file provides a command line example
to explain how to build, but it places -lgcc before the source,
which usually fails with libgcc.a (e.g. on ARM when uidiv is
needed). Let's fix this before it leaks into makefiles.
