Return from ddr3_tip_print_log() early if we won't print anything anyway.

This way the compiler can optimize away the VALIDATE_IF_ACTIVE() calls in the for-loop, so if the SILENT_LIB macro is defined, no code is generated for the rest of the function, which saves some space.

The variables is_validate_window_per_if, is_validate_window_per_pup, sweep_cnt and is_run_leveling_sweep_tests are only used if DDR_VIEWER_TOOL macro is defined, so define them only in that case.

Make them static since they are only used in ddr3_debug.c.

When the 'eeprom' command (with layout support) is enabled, we can now use the 'eeprom print' and 'eeprom update' commands, for example:

Import DDR training code from commit 1b69ce2fc0ec ("arm: mvebu: ddr3_debug: remove self assignments") into drivers/ddr/marvell/a38x/old/. The code is not used yet.

Explanation:

Since 2019, on some Turris Omnia boards we have been having problems with newer versions of Marvell's DDR3 training code for Armada 38x, which is ported from mv-ddr-marvell [1] to U-Boot into the drivers/ddr/marvell/a38x/ directory: - sometimes the DDR3 training fails on some older boards, sometime it fails on some newer boards - other times it succeeds, but some boards experience crashes of the operating system after running for some time.

Using the stock version of Turris Omnia's U-Boot from solved these issues, but this solution was not satisfactory, since we wanted features from new U-Boot.

Back in 2020-2022 we have spent several months trying to debug the issues, working with Marvell, on our own, and also with U-Boot community, but these issues persist still.

One solution we used back in 2019 was a "hybrid U-Boot": the SPL part (containing the DDR3 training code) was taken from the stock version, while the proper part was current U-Boot at the time. This solution also has its drawbacks, of which the main one is the need to glue binaries from two separate builds.

Since then there have been some more changes to the DDR3 training code in upstream mv-ddr-marvell that have been ported to U-Boot. We have provided our users experimental builds of U-Boot in the TurrisOS so that they could try upgrading the firmware and let us know if those problems still exist. And they do.

We do not have the time nor manpower to debug this problem and fix it properly. Marvell was also no able to provide a solution to this, probably because they do not have the manpower as well.

I have therefore come up with this "not that pretty" solution: take the DDR3 training code from an older version of U-Boot that is known to work, put it into current U-Boot under old/ subdirectory within drivers/ddr/marvell/a38x/, build into the SPL binary both the old and new versions and make it possible to select the old version via an env variable.

Users experiencing DDR3 initialization failures or random crashes of the operating system due to incorrect DDR3 configuration can select the old DDR3 training implementation to fix those issues by setting the EEPROM field "Use old DDR training": eeprom update "Use old DDR training" 1
