K3 devices have firewalls that are used to prevent illegal accesses to
memory regions that are deemed secure. The series prevents the illegal
accesses to ATF and OP-TEE regions that are present in different K3
devices.
AM62X, AM62AX and AM64X are currently in hold due to some firewall
configurations that our System Controller (TIFS) needs to handle.
The devices that are not configured with the firewalling nodes will not
be affected and can continue to work fine until the firewall nodes are
added so will be a non-blocking merge.

Many nodes are reused between WKUP SPL, MAIN SPL, and U-Boot. Using
bootph-pre-ram is causing these nodes to be present in SPL builds but
pruned away during the U-Boot build. Convert these nodes to bootph-all
so they will remain no matter which dtb build is happening.

Ethernet is one of a few IPs in U-Boot that depend on DMA to operate.
However there are a few missing registers ranges in the udmap nodes
need to properly setup DMA for the am65x.
A fix has been added to the Linux kernel[0] to add these ranges however
they have not made it to a Linux tag. To keep DMA operational until the
next DT sync from Linux, add these ranges to the *-u-boot.dtsi with a

This series continues refactoring the bootm code to allow it to be used
with CONFIG_COMMAND disabled. The OS-handling code is refactored and
a new bootm_run() function is created to run through the bootm stages.
This completes the work.
A booti_go() function is created also, in case it proves useful, but at
last for now standard boot does not use this.
This is cmdd (part d of CMDLINE refactoring)
It depends on dm/bootstda-working
which depends on dm/cmdc-working
Use the new bootm/z_run() functions to avoid having to create an
