Many nodes are reused between WKUP SPL, MAIN SPL, and U-Boot. Using
bootph-pre-ram is causing these nodes to be present in SPL builds but
pruned away during the U-Boot build. Convert these nodes to bootph-all
so they will remain no matter which dtb build is happening.

This dummy_clock isn't a device that exists nor does it exist in the

Currently the wget command is hard wired to HTTP port 80. This is
inconvenient, as it is extremely easy to start trivial HTTP server
as an unprivileged user using e.g. python http module to serve the
files, but such a server has to run on one of the higher ports:
"
$ python3 -m http.server -d $(pwd) 8080
"
Make it possible to configure HTTP server port the same way it is
possible to configure TFTP server port, using environment variable
'httpdstp' (similar to 'tftpdstp'). Retain port 80 as the default
fallback port. This way, users can start their own trivial server

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 and for 2 GiB device the available DRAM size
