Add support for building U-Boot SPL for Renesas R-Car Gen4 R8A779G0 V4H SoC.
The SPL initializes the DBSC5 DRAM controller, RT-VRAM and loads and starts
U-Boot proper on the Cortex-A76 core.
The SoC BootROM can not boot the CA76 core directly, instead the SPL starts
on the CR52 core which immediately brings up the CA76 core, which in turn
starts executing the actual SPL. This is achieved by placing a tiny bit of
precompiled Aarch32 code at the very beginning of the SPL. The code consists
of some 32 instructions, uses APMU to configure CA76 start address to offset
0x80 Bytes from start of the SPL, and uses APMU to start the CA76 core. The
code parts the CR52 core in an endless loop once the CA76 core got started.
The 32 instructions are completely arbitrary number, so is the offset 0x80
Bytes from start of SPL, because 0x80 = 128 decimal and 128 / 4 bytes per
instruction is 32 instructions. The 32 instructions turned out to be enough
to started the CA76 and 0x80 is nicely aligned.
Once the SPL completes hardware initialization, the SPL loads U-Boot proper.
The u-boot.itb proper fitImage contains 64bit build on u-boot-nodtb.bin and
a DT for R8A779G0 V4H White Hawk board and is generated by binman. The
u-boot.itb is loaded from SPI NOR offset 0x80000.
In order to install this setup on an existing R8A779G0 V4H White Hawk board,
build using r8a779g0_whitehawk_defconfig, generate SPI NOR image flash.bin
and write flash.bin to SPI NOR offset 0x0 . Finally, configure board MD pin
switches according to the R8A779G0 V4H White Hawk board documentation for
40 MHz SPI NOR boot using DMA and restart the board.

In case U-Boot runs in EL3, which is the highest privilege level on ARM64,
there can be no firmware running that would restrict access to the bottom
128 MiB of DRAM. In fact, it is likely that U-Boot would have to load that
firmware into those bottom 128 MiB of DRAM and start that firmware.
Make those bottom 128 MiB of DRAM available in case U-Boot runs in EL3 to
allow loading the firmware to that area.

This returns a devicetree and updates a parameter with an error code.
Swap it, since this fits better with the way U-Boot normally works. It
also (more easily) allows leaving the existing pointer unchanged.
No yaks were harmed in this change, but there is a very small code-size
reduction.
For sifive, the OF_BOARD option must be set for the function to be
called, so there is no point in checking it again. Also OF_SEPARATE is

Simplify module version handling by removing the special case for the
Apalis iMX8QM.
The Apalis iMX8QM has been treated as a special case in module version
handling, but was always the default. By removing this special handling,
the code is simplified and easier to maintain.
We will not print the message "Unknown Apalis iMX8 module" anymore.
However, we still handle this because if the config block is missing we
show "MISSING TORADEX CONFIG BLOCK" and if the serial number is unknown
we show "Model: Toradex 0000 UNKNOWN MODULE V1.1A". Therefore, it is
still possible to detect such issues.

Hello,
This series adds support for USB DFU boot on TI's AM62A SoC which has
two instances of DWC3 USB Controllers namely USB0 and USB1. The USB0
instance of the USB Controller supports USB DFU boot:
ROM => tiboot3.bin => tispl.bin => u-boot.img
USB DFU Boot requires the USB Controller to be configured for Gadget
mode of operation. Since the USB0 instance of the DWC3 USB Controller
supports both Host and Gadget modes of operation via the Type-C interface
on the AM62A7-SK board, the device-tree specifies the "dr_mode" as "OTG".
However, there is currently no support for dynamically switching the "mode"
from Host to Gadget and vice-versa with the help of a state-machine.
The OTG mode is treated as a separate mode in itself rather than being
treated as an intermediate stage before assuming the Host/Gadget mode.
Due to this, USB DFU boot via the Type-C interface doesn't work as the
USB Controller hasn't been appropriately configured for Device/Gadget
mode of operation. One option is to change the device-tree to specify
"dr_mode" as "peripheral" and force the controller to assume the Device
role. This will imply that the U-Boot device-tree for AM62A diverges
from its Linux counterpart. Therefore, with the intent of keeping the
device-tree uniform across Linux and U-Boot, and at the same time, in
order to enable USB DFU boot in "OTG" mode with the DWC3 Controller,
the first patch in this series sets the "mode" on the basis of the
caller function, rather than using the "dr_mode" property in the
device-tree. There are only two callers of "dwc3_generic_probe()",
each of which clearly specify the expected mode of configuration.
This will enable both Host and Device mode of operation based on the
command executed by the user, thereby truly supporting "OTG"
functionality when the USB Controller supports it.
The second patch in this series adds USB DFU environment for AM62A,
enabling USB DFU Boot and USB DFU flash on AM62A.
In addition to the patches in this series, the following device-tree
changes will be required to test USB DFU on AM62A (bootph-all property
to be added to ensure that USB Controller is present at all stages
for DFU Boot):
https://gist.github.com/Siddharth-Vadapalli-at-TI/53ba02cb0ff4a09c47e920d08247065f
The above device-tree changes will be made to the Linux device-tree,
which shall ensure that the same shall be a part of U-Boot device-tree
eventually.
The USB DFU config fragments for AM62x have been used for enabling
USB DFU boot on AM62a as follows:
R5 => am62ax_evm_r5_defconfig + am62x_r5_usbdfu.config
A53 => am62ax_evm_a53_defconfig + am62x_a53_usbdfu.config

The new i.MX8M Plus DHCOM rev.200 is populated with M24C32-D EEPROM
that contains an additional write-lockable page called ID page, which
is populated with a structure containing ethernet MAC addresses, DH
item number and DH serial number.
Because the write-lockable page is not present on rev.100 i.MX8MP DHCOM
SoM, test whether EEPROM ID page exists by setting up the i2c driver.
There may be multiple EEPROMs with an ID page on this platform, always
use the first one. The evaluation of the EEPROM ID page is done in two
steps. First, the content is read and checked. This is done to cache
the content of the EEPROM ID page. Second, the content is extracted
from the EEPROM buffer by requesting it.
For the ethernet MAC address the i.MX8M Plus DHCOM currently supports
parsing address from multiple sources in the following priority order:
1) U-Boot environment 'ethaddr'/'eth1addr' environment variable
2) SoC OTP fuses
3) On-SoM EEPROM
