| Series | Turris Omnia DDR training changes | expand |
Hi Marek, I'm running a regression test with this patch on another Armada 385 board (Synology DS116). And it is running without problem. I noticed that there is no version bump. Is this still 14.0.0? It's kind of hard to see which version we are using without a minor revision such as 14.0.1.

Hi Tony, hmm no I did not change the version number. The changes are only relevant for debug messages, there is no functional changes in how the DDR training is done, unless I made a mistake. I am not sure that changing the version is a good idea unless this is also done for the upstream where I sent the PR. But who knows if Marvell will have some people assigned to merge the PR. Since U-Boot prints its own version, people can easily reproduce the code for a given binary from U-Boot version string.

Hi Stefan, this series adds some changes to DDR3 training for Armada 38x and Turris Omnia. - patches 1-4 are meant to allow for reducing another 10 KiB in the SPL binary. They were also sent to mv-ddr-marvell, via PR on github, https://github.com/MarvellEmbeddedProcessors/mv-ddr-marvell/pull/45/ but I am told that Armada team has left Marvell, so who knows if this will ever be merged there - patch 5 enables this reduction for Turris Omnia - patches 6-8 import old DDR3 training code and make some changes so that it works with U-Boot. The reason why this is being done is explained in patch 6 - patch 9 glues the old DDR3 training code to current U-Boot - patch 10 allows for dynamic selection of old DDR3 training code on Turris Omnia, via an U-Boot environment variable Marek Marek Behún (10): ddr: marvell: a38x: debug: return from ddr3_tip_print_log() early if we won't print anything ddr: marvell: a38x: debug: Remove unused
