The Embedded Artists COM board is based on NXP i.MX7ULP.
It has a BD70528 PMIC from Rohm with discrete DCDC powering option and
improved current observability (compared to the existing NXP i.MX7ULP EVK).
Add the initial support for the board.

We switch from custom boot commands relying on uEnv.txt to distro boot.
This removes the automatic fpga bitstream loading in favor of loading
bitstreams via custom bootscripts (boot.scr) or after booting the
kernel.

Make first step in DT/DM migration. Enable OF_CONTROL only for the main
U-Boot image for now.
Remove mmc_init_main() because board_mmc_init() is not called when
DM_MMC is enabled.
DM_MMC requires DM_GPIO for card-detect to work. That in turn makes gpio
request mandatory. Add code to request/free gpios in platform code.
MMC devices are now numbered according to DT. The SD card is 1, and eMMC
is 2. Account for that in board_mmc_get_env_dev(), BOOT_TARGET_DEVICES,
and has_emmc().
DM_MMC requires BLK. However, the (BLK && !DM_USB) combination disables
USB_STORAGE. Enable DM_USB to preserve USB functionality. Add also
DM_REGULATORS for the USB power controller. This allows us to drop
board_ehci_hcd_init() and setup_usb().
Runtime selection of DT is necessary because of the i.MX6QD vs i.MX6SDL
incompatibility. DT selection does not rely on GPIOs, since DM_GPIO
depends on DT. Instead, we take one "fully featured" DT of each variant.
That should be enough to boot from both SD card and eMMC.
Since we don't select the exact DT, override the generic
show_board_info() that shows the selected DT 'model' field.

DM for PCI pulls DM for ethernet that also needs other changes described
below to build u-boot and keep existing functionality - ability to update
MAC addresses of FEC ethernet adapter and I210 adapter connected to the
Marvell switch.
- fec_mxc driver with DM needs PHYLIB;
- configuration items are moved from ge_bx50v3.h to ge_bx50v3_defconfig;
- FEC is marked as eth0 because it is always present, so indices changed:
I210 are still probed in the same order;
- board_eth_init() was used by legacy ethernet, setup for enet iomux and
pcie is moved to the board_late_init();
- pci_init() is called from the board_late_init() to initiate PCI bus
probing, so I210 devices are propagated to the device tree;

U-Boot binary has grown in such a way that it goes beyond the reserved
area for the environment variables.
Running "saveenv" followed by a "reset" causes U-Boot to hang because
of this overlap.
Fix this problem by increasing the CONFIG_ENV_OFFSET size.
Also, in order to prevent this same problem to happen in the future,
use CONFIG_BOARD_SIZE_LIMIT, which will detect the overlap in build-time.
CONFIG_BOARD_SIZE_LIMIT does not accept math expressions, so declare
CONFIG_ENV_OFFSET with its direct value instead.

- Add OF_SEPARATE support for SIFIVE FU540.
- Add SPL support for Andes AX25 AE350.
- Improve U-Boot SPL / OpenSBI smp boot flow for RISC-V.
OpenSBI uses a relocation lottery to determine the hart to relocate
OpenSBI to its link address. In the U-Boot SPL boot flow, the main hart
schedules the secondary harts to enter OpenSBI before doing so itself.
One of the secondary harts will therefore always be the winner of the
relocation lottery. This is problematic if the link address ranges of
OpenSBI and U-Boot SPL overlap. OpenSBI will be relocated and therefore
overwrite U-Boot SPL while some harts may still run it, leading to code
corruption.
Avoid this problem by specifying the main hart as the preferred boot
hart to perform the OpenSBI relocation. The main hart will be the last
hart to enter OpenSBI, relocation can therefore occur safely.
The boot hart field was added to version 2 of the OpenSBI FW_DYNAMIC
info structure. The header file include/opensbi.h is synchronized with
include/sbi/fw_dynamic.h from the OpenSBI project to update the info
structure. The header file is recent as of commit
7a13beb21326 ("firmware: Add preferred boot HART field in struct
fw_dynamic_info").
