When software developers drive
hardware design it means adaptable
SoC’s have won.

Rebase Kernel Tree
˃ Merge-Tree
Merges two separate branches into a single new branch going forward
Lose the history of what was different between the branches
˃ Rebase Tree
Creates a series of patches that can be applied cleanly to the HEAD node
Maintain history of development in the separate development paths
˃ Single upstream kernel version per year
˃ Rebase patchsets with Vivado releases
˃ Rolling merge tree
