Taking inspiration from Heiko's patch[1] this series goes and cleans up
all of the arch/arm/dts/*.h files that can be easily removed. The big
challenge I ran in to here was that for some platforms that aren't using
OF_UPSTREAM were didn't have a sufficiently deep search path to find
files there rather than arch/arm/dts. This also showed that only ARM had
local header files to deal with.

The NanoPi RK3399 boards support UHS-I (up to SDR104) SD cards, however
using any of these 1.8v modes results in a boot failure in SPL upon soft
reboot.
The issue is that the "vcc_sdio" regulator is left at 1.8v on reboot
and the corresponding GPIO defaults to 3.3v. This prevents the SD card
from being reinitialized and read successfully.
This change enables the RK8XX regulators and Rockchip IO-domain drivers
in SPL, which initializes "vcc_sdio" regulator to 3.0v and configures
the GPIO for the correct level on boot.

This change removes the "regulator-always-on" property from the
"vcc3v0_sd" (vmmc-supply) and "vcc_sdio" (vqmmc-supply) regulators,
which otherwise prevents the MMC driver from being able to power cycle
the SD card as part of the initialization procedure.
It also removes the "regulator-boot-on" from the "vcc_sdio" regulator,
which could theoretically damage a SD card that is already initialized
in a low voltage mode.

Hey all,
Related to my other series I've posted recently on cleaning up some
headers, this series here is the result of at least lightly auditing the
#includes used in include/[a-m]*.h. This ignores subdirectories, as at
least in part I think the top-level includes we've constructed are the
most likely places to have some extra transitive include paths. I'm sure
there's exceptions and I'll likely audit deeper once this first pass is
done. This only gets as far as "include/m*.h" because I didn't want this
to get too big. This also sets aside <miiphy.h> and <phy.h>. While
miiphy.h does not directly need <phy.h> there are *so* many users and I
think I had half of the tree just about not building when I first tried.
It might be worth further investigation, but it might just be OK as-is.

Although AM62x, AM62Ax, AM64x, and AM62Px share the same register for
reset reason, not all TRMs document this consistently. To avoid relying
on undocumented behavior, introduce SoC-specific implementations for
now. If TI confirms all SoCs share the same register, this can be moved to
common.c for reuse.
It will be mostly copy&paste for the mentioned devices.
Also, I am not sure how this Register operates exactly. I noticed that
two bits can be set at once, so I started to check for set bits instead
of having a switch/case logic.

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.
