Applies to master and to u-boot-marvell, but you need the 6
additional patches for kwbimage/kwboot that are on patchwork
but not yet applied to u-boot-marvell:
  https://patchwork.ozlabs.org/project/uboot/list/?series=257577
  https://patchwork.ozlabs.org/project/uboot/patch/20210817050320.11983-1-xypron.glpk@gmx.de/
  https://patchwork.ozlabs.org/project/uboot/patch/20210817051158.13283-1-xypron.glpk@gmx.de/

Also some more fixes were yet needed, which I will sent in v2.

To make it simpler for you I pushed v2 into
  https://gitlab.nic.cz/turris/turris-omnia-uboot
branch
  kwboot-baudrate-improvements
