Implement fdtdec_board_setup() auto-detection of ethernet PHY.
This uses properties of the hardware and pull resistor placement.
If GPIO1_16 RGMII_MDC is HIGH, then R530 (MX8MM eDM SBC) or
R390 (MX8MP eDM SBC) is populated. R530 or R390 is populated
only on boards with AR8031 PHY.
If GPIO1_16 RGMII_MDC is LOW, then the in-SoM pull down is the
dominant pull resistor. This is the case on boards with BCM54213PE
PHY.
In case AR8031 PHY is populated, the PHY MDIO address is 0, in
case BCM54213PE PHY is populated, the PHY MDIO address is 1, the
fdtdec_board_setup() is used to patch the correct address into
the U-Boot control DT.
Enable broadcom PHY support to support both PHYs.

Import DRAM timings generated by the DDR tool 3.31 which introduce assorted
tweaks to the DRAM controller settings. Furthermore, enable DBI to improve
noise resilience of the DRAM bus by reducing the number of bit changes on
the bus.
Reduce the DRAM rate to 3600 MTps to remove all remaining correctable errors
reported by EDAC . It is not entirely clear why the slightly faster setting
does produce sporadic correctable errors, while this one does not, but this
could be related to simpler PLL setting at 3600 MTps.
Enable inline ECC which is necessary to detect ECC errors and collect
statistics by the EDAC driver in Linux. This reduces the DRAM size by
64 MiB for each 512 MiB of DRAM, so for a 4 GiB device the available
DRAM size becomes 3.5 GiB .

Enable CAAM in U-Boot to make crypto available early in the boot process.
This has a side-effect that in case an older kernel version contains a
broken CAAM initialization timeout code, initialization in bootloader
will help that old kernel version function correctly.

Enable support for TCP protocol, wget, and IPv6 on this platform.
The former two allow users download payload into the U-Boot from
a web server, which may be more convenient or easier to set up
than TFTP server. The later is enabled to future proof the IP
stack on this platform.

We like to put the SPL first so it is clear that it relates to SPL. Rename
various malloc-related options which have crept in, to stick to this
convention.

Use default SAVED_DRAM_TIMING_BASE as that is what upstream TFA expects.
Without this change, the board will fail to suspend/resume e.g. in Linux.

It is not a parse error to have a default value of "0" for a "hex" type
entry, instead of "0x0". However, "0" and "0x0" are not treated the
same even by the tools themselves. Correct this by changing the default
value from "0" to "0x0" for all hex type questions that had the
incorrect default. Fix one instance (in two configs) of a default of "0"
being used on a hex question to be "0x0". Remove the cases where a
defconfig had set a value of "0x0" to be used as the default had been
"0".
