The current DDR subsystem configuration occasionally results in write failures,
impacting memory stability, on Verdin AM62 Solo 512MB WB IT 0072 SKU.
This commit addresses the issue by adjusting Drive Pull-Up/Down and
Write Latency to improve the eye diagram and ensure reliable write operations.
This configuration is shared with all Verdin AM62 SoM and
it does not introduce regressions.
Configurations changes from previous / default values:
- Drive Pull-Up/Down from 40 to 34.3 Ohm
- Write Latency from 8 to 10
- ODTLon / ODTLoff latency from 0 / 0 to 4 / 20 nCK
- VREF control range 1 at 27 %
- tFAW from 30 to 40 ns
Configuration is output from SysConfig [1] web tool, currently at version
1.18.1+3343 (DDR SubSystem v9.10).

Pull request for efi-next-20231217
Documentation:
* replace MD5 and SHA1 by SHA256 in examples
UEFI:
* Refactor boot manager and bootefi command to let the EFI boot method work
without shell.
Both SHA1 and (especially) MD5 are no longer as safe as they once were for
cryptographic use. Replaces examples which use them with examples using
SHA256 instead. This will provide more-secure defaults for users who use
documentation examples as a base for their own use. This is not too
necessary for non-verified-boot scenarios (since someone could just replace
the checksum), but I wanted to be complete.

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
becomes 1.8 GiB.

In case the Buck5 and Buck6 regulators which supply DRAM Vdd1 and Vdd2/Vddq
respectively operate in automatic PWM/PFM mode, the DRAM EDAC detects more
correctable errors than if the regulators operate in forced PWM only mode.
Force DRAM regulators to forced PWM mode only to stop tempting the DRAM.

All normal memory areas should be mapped as such.
We added these un-cached holes in our memory map to hack around the
remoteproc driver missing the proper cache maintenance operations.
The problem is having these non-cached memory map areas causes stability
issues later in system operation due to the nature of the K3 coherency
architecture. Plus these are board specific carveouts and instead
should have been added at the board level, not here in the SoC common
code area.
Remove these non-cached memory map areas.
