remove boot logic from shared env file for phyboard-polis and
phygate-tauri.
Adjust configs for both boards as well.
Space at the beginning of addressable RAM is reserved for space used via
standard boot env variables. CONFIG_SYS_LOAD_ADDR is set to the lowest
address behind the standard boot variables reserved space.

Our last sync with the kernel was 5.1. Even that was a partial one
as some patches from 4.x kernels were already missing making the
transition to a modern kbuild infeasible.
We are so out of sync now, that tracking the patches and backporting
them one by one makes little sense and it's going to take ages.
This is an attempt to sync up Makefile[.lib/.kbuild].
Unfortunately due to sheer amount of patches this is not easy to review,
but that's what we decided during a community call.
One of the biggest changes is get rid of partial linking entirely and
build .a archives isntead of .o.
We diaviate from the kernel on that. Instead of calling a custom script
to create the archive symbol table, we call ar with rcTP (isntead of
rcSTP) since we want a resulting archive that's sauble with the linker.
The only affected platforms are PPC ones. Unfortunately I don't have any
of them around to test, but the objdump of the resulting files --
arch/powerpc/lib/built-in.[oa] looks identical.

Rename the variable and add ENV_ prefix, so that all configuration
options which are related to environment would have an CONFIG_ENV_
prefix. No functional change.

Hey all,
This is a v3 of Simon's series[1] and depends on the series[2] I posted
the other day that removes <env.h> from <command.h>. With this series
done, I believe we've tackled all of the current cases of headers which
include <env.h> without directly needing it. Much of this series is in
fact Simon's v2 with the main differneces being:
- Removing <env.h> from <net.h> at the end
- Removing env_to_ip() given how little it's used rather than shuffling
around where it's declared and un-inline'ing it. For a rarely used
helper, this ends up being cleaner I think. Especially looking at some
of the users (which called env_get repeatedly). If there's strong
opinion here about using the other method[3] we can do that instead.
- Setting aside for now how to handle CMD_ELF=y and NO_NET=y because
today it's actually fine as we unconditionally build lib/net_utils.c
where string_to_ip() is defined. I'm unsure if a further series is
warranted here or not. We rely on link-time optimization to keep code
readable too.

The write_host_id is the last element here and order does matter. This

if this is updated to a different host, it will not work. Update

After probing, call into k3-ddrss driver to fixup device tree and resize

as done from R5 SPL and apply it to DT passed to A53 U-boot,
