Beacon Embedded has an i.MX8M Plus development kit which consists
of a SOM + baseboard. The SOM includes Bluetooth, WiFi, QSPI, eMMC,
and one Ethernet PHY. The baseboard includes audio, HDMI, USB-C Dual
Role port, USB Hub with five ports, a PCIe slot, and a second Ethernet
PHY. The device trees are already queued for inclusion in Linux 6.3.

Add support to Verdin IMX8MP V1.1B SKU which uses
MT53E1G32D2FW-046 WT:B memory.
Compared to the 8 GB memory (MT53E2G32D4NQ-046 WT:A) used on
Verdin IMX8MP V1.0A it has 16 row addresses instead of 17.
In fact, the new memory, is a 2 GB/rank memory. The 8 GB memory is a
4 GB/rank memory.
Manually tweaking Host Interface addresses vs LPDDR4 signals mapping it
is possible to have a single configuration working with both memories:
- Old configuration: HIF bit 30 -> rank, HIF bit 29 -> Row 16
- New configuration: HIF bit 29 -> rank, HIF bit 30 -> Row 16
With this change the memory space from the host processor is contiguous
for both the configurations and the correct memory size is computed
using get_ram_size() at runtime.
Support for single rank memories still works thanks to the fact
dual ranks training fails (ddr_init->ddr_cfg_phy) toward single rank
memories.

U-Boot can be booted from NAND without SPL by prepending the DCD header to
the actual U-Boot binary. However this requires prepending 1024 bytes to
u-boot.imx (DCD + u-boot.bin).
There is already a similar target to build spl/u-boot-nand-spl.imx, add the
same option for no-SPL boot.
Tested on i.MX6ULL.
The resulting layout of u-boot-nand.imx is:
- Offset 0x0000 (0 KiB): padding
- Offset 0x0400 (1 KiB): DCD header
- Offset 0x1000 (4 KiB): u-boot.bin

Enable SDP protocol support in SPL for DH i.MX6 DHSOM, now that those
components fit into the SPL due to LTO.
To start U-Boot via SDP upload on i.MX6 DHSOM based board, proceed as follows:
- Compile imx_usb [1] .
- Power off the i.MX6 DHSOM based board.
- Connect both USB-serial console and USB-OTG miniB ports to host PC.
- Switch board to USB boot mode.
- Power on the board.
- Verify using '$ dmesg' that a new device has been detected as follows:
New USB device found, idVendor=15a2, idProduct=0054, bcdDevice= 0.01
New USB device strings: Mfr=1, Product=2, SerialNumber=0
Product: SE Blank ARIK

- Upload U-Boot SPL:
$ imx_usb u-boot-with-spl.imx
- Wait for SPL to come up, the following print ought to be the last on
UART console:
SDP: handle requests...
- Upload U-Boot proper:
$ imx_usb u-boot.img

There can certainly be a lot more elements in the "revisions" (and
"names") arrays than there are gpios used to form the trinary number
we're searching for; we simply don't know the array size up-front.
Nor do we need to, because the loop body already knows to recognize
-EOVERFLOW as "not that many elements present" (and we have a test
that specifically ensures that dev_read_u32_index() returns exactly
that). So just drop the i < priv->gpio_num condition.
