board: verdin-imx8mp: update ddrc config for different lpddr4 memories
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.

net: dwc_eth_qos: Set DMA_MODE SWR bit to reset the MAC
The driver currently only waits for DMA_MODE SWR bit to clear itself.
This is insufficient e.g. on i.MX8M Plus, where the MAC must be reset
before IOMUX GPR[1] content is latched into the MAC and used. Without
the proper reset, the i.MX8M Plus MAC variant does not take the value
in IOMUX GPR[1] into account, which makes it impossible e.g. to switch
interface mode from RGMII to any other.
Since proper reset is desired in general to put the block into defined
state, always assert the DMA_MODE SWR bit before waiting for the bit
to clear itself.

arm: mvebu: Remove A38x BOOT_FROM_SATA 0x22 constant
A385 BootROM treats strapping configuration 0x22 as SPI-NAND. So remove
incorrect definition 0x22 as SATA. SATA on A385 has configuration 0x2A.

arm: mvebu: Remove A38x BOOT_FROM_UART_ALT 0x3f constant
A385 BootROM treats strapping configuration 0x3f as invalid. When booting
fails (e.g. because of invalid configuration) then BootROM fallbacks to
UART booting.
Detecting BootROM fallback to UART booting is implemented in U-Boot since
commit
2fd4284051e3 ("ARM: mach-mvebu: handle fall-back to UART boot").
So there is no need to define BOOT_FROM_UART_ALT constant and special
handling for it anymore, remove it.
This change effectively revers commit
f3a88e2ca17a ("arm: mvebu: fix boot
from UART on ClearFog Base").

arm: mvebu: clearfog: Detect MMC vs SDHC and fixup fdt
[upstream of vendor commit
19a96f7c40a8fc1d0a6546ac2418d966e5840a99]
The Clearfog devices have only one SDHC device. This is either eMMC if
it is populated on the SOM or SDHC if not. The Linux device tree assumes
the SDHC case. Detect if the device is an eMMC and fixup the device-tree
so it will be detected by Linux.

A388 Clearfog MMC is either SD Card or eMMC with different behaviour for
