on at least one platform:

We can just include both the pxa168.h and pxa910.h headers to make
that work, which gets us to the next failure:

Change that as well to fix the build error, and rename the

what is actually going on.

I saw that the high 6500000 HZ frequency was previously only
set with CONFIG_MMP2, but is now also used with MMP (pxa910),

The i.MX 7ULP family of processors features NXP's advanced implementation
of the Arm Cortex-A7 core, the Arm Cortex-M4 core, as well as a 3D and 2D
Graphics Processing Units (GPUs).

This patch aims to add an initial support for imx7ulp. Note that we need
configure power mode to Partial Stop mode 3 with system/bus clock enabled
first as the default enabled STOP mode will gate off system/bus clock when
execute WFI in MX7ULP SoC.

And there's still no MXC_CPU_IMX7ULP IDs read from register as ULP has no
anatop as before. So we encode one with 0xff in reverse order in case new
ones will be in the future.

If debugging on i.MX is enabled DEBUG_IMX_UART_PORT defines which UART
is used for the debug output. If however debugging is off don't only
hide the then unused config item but drop it completely by using a

if DEBUG_LL is disabled.
