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
