Update LPDDR4 configuration and training using updated spreadsheet and
tools from NXP using data from previous spreadsheet and verified
toward datasheet:
- MX8M_Plus_LPDDR4_RPA_v9.xlsx
- mscale_ddr_tool_v3.30.exe
From:
https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/i-MX-8M-Family-DDR-Tool-Release/ta-p/1104467
Some register values differ due to these fixes/modifications:
- corrected calculation of T_CKPDX parameter (equal to tCKCKEH for LPDDR4)
- corrected ECC related items, none of which affect normal operation
when ECC is not enabled
- corrected formula for calculation of tRTP in cell D122

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.

The EQoS interface mode is now configured in common board_interface_eth_init()
and called by EQoS MAC driver when appropriate. Drop the board side duplicates
if the same functionality.

The PCA9450 reset configuration can now be performed by the PCA9450 PMIC
driver itself, remove the hard-coded variant from board code and let the
PMIC driver perform this task using one-liner:
```
$ sed -i '/set WDOG_B_CFG to cold reset/,+2 d' $(git grep -l PCA9450_RESET_CTRL.*0xA1 board/)
```
Venice and i.MX93 EVK required slight manual fix up.

Add RAM auto-sizing, without this change memory size for all SKU is set
to 8GB and the system will crash on SKU with less memory as soon as the
non existent memory addresses are accessed.

Synchronise device tree with linux v5.19-rc5.
Please note that this also means that instead of the previous "generic"
U-Boot specific carrier board agnostic device tree we are now using the
regular one for the Verdin Development (carrier) board (e.g.
imx8mp-verdin-wifi-dev.dtb rather than the previous imx8mp-verdin.dtb).

pinctrl_wdog already marked u-boot,dm-spl, so clean up board code.
The set_wdog_reset() function is not necessary as this is handled by
the imx_watchdog.c driver due to the 'fsl,ext-reset-output' property
being set.

This adds initial support for the Toradex Verdin iMX8M Plus Quad 4GB WB
IT V1.0B module. They are strapped to boot from eFuses which are factory
fused to properly boot from their on-module eMMC. U-Boot supports
booting from the on-module eMMC only, SDP support is disabled for now
due to missing i.MX 8M Plus USB support.
Functionality wise the following is known to be working:
- eMMC, 8-bit and 4-bit MMC/SD card slots
- Ethernet both on-module eQoS and FEC (requires PHY on carrier board)
- GPIOs
- I2C
Boot sequence is:
SPL ---> ATF (TF-A) ---> U-boot proper
ATF, U-boot proper and u-boot.dtb images are packed into a FIT image,
loaded by SPL.
