This doesn't have any methods so is not good as a class. Make it a

* Qualcomm platforms >~2016 gain support for the RPMh (Resource Power Manager)
peripheral which is used to control most regulators. The RB5 is now able to
power up its USB VBUS regulator via the rpmh regulator driver. Git history
from the original Linux driver is preserved for ease of maintenance.
* IPQ40xx SoCs gain ethernet networking support via the new ESS EDMA driver.

IPQ4019 ESS EDMA support is not yet in upstream Linux, so for now lets use
the latest pending Linux DTS node for wired networking.

This adds the driver for the ESS EDMA ethernet adapter
found inside of Qualcomm IPQ40xx SoC series.
This driver also integrates the built in modified QCA8337N
switch support as they are tightly integrated.

A lot of the features in here are only relevant when running
multi-threaded with interrupts. Drop everything except what we need to
run single-threaded with a single TCS (which is all the rpmh-rsc
framework in U-Boot supports).
Keep rpmh_write_async() for simplicity and make it wrap the regular
rpmh_write().

Since U-Boot is single threaded, we can avoid most of the complexity

Keep the header pointer in the .data section so we don't initialize it
again after relocation, adjust cmd_db_get_header() to work with the
U-Boot API, and skip validating the header since all cmd-db users are
children of the rpmh-rsc and those children will only probe if cmd-db
initializes successfully.

Integrate cmd-db into the U-Boot driver model.
This is just a wrapper around an in-memory database, so we just need to
get the address and validate that cmd-db is there.
Since cmd_db_header will be stored in the .data section we can skip
bind if it's already set.

Enable True Random Number Generator (TRNG) on E850-96 board. To do so:
1. Enable DM_RNG and RNG_EXYNOS for TARGET_E850_96
2. Add TRNG node to E850-96 device tree
3. Enable 'rng' command support for easy TRNG testing
TRNG node is already applied in Linux kernel device tree, but it hasn't
appeared in upstream dts yet. Add it in U-Boot override dtsi file
temporarily; it can be removed once it appears in upstream dts.

Add True Random Number Generator (TRNG) driver for Exynos chips. This
implementation is heavily based on Linux kernel's counterpart [1]. It
also follows upstream dt-bindings [2].
TRNG block is usually a part of SSS (Security Sub System) IP-core on
Exynos chips. Because SSS access on Exynos850 is protected by TZPC
(TrustZone Protection Control), it's not possible to read/write TRNG
registers from U-Boot, as it's running in EL1 mode. Instead, the
corresponding SMC calls should be used to make the secure software
running in EL3 mode access it for us. Those SMC calls are handled by
LDFW (Loadable Firmware), which has to be loaded first. For example, for
E850-96 board it's done in its board_init(), so by the time RNG
capabilities are needed the LDFW should be already loaded and TRNG
should be functional.

LDFW is a Loadable Firmware which provides additional security
capabilities in EL3 monitor. For example, True Random Number Generator
(TRNG) block registers can't be accessed from EL1 (where U-Boot and
Linux kernel are running), but it's possible to access TRNG capabilities
via corresponding SMC calls, which in turn are handled by LDFW. To do
so, LDFW firmware has to be loaded first. It's stored on a raw eMMC
partition, so it has to be read into NWD (Normal World) RAM buffer, and
then loaded to SWD (Secure World) memory using the special SMC call to
EL3 monitor program. EL3_MON will load LDFW to SWD memory, more
specifically to the area starting at 0xbf700000 (with size of 7.5 MiB).
That memory area is reserved in device tree, so there shouldn't be any
collisions. After that LDFW becomes functional.
Implement LDFW firmware loading on board init. While at it, fix the
copyright date in header comments, as this board support was actually
added in 2024, not in 2020: it was probably a copy-paste mistake.
