Arria 10 PCIe Root Port with MSI sample design, missing Tag/Branch for linux-socfpga

Hi,

I’m working on adding PCIe root complex support to an A10 and using [1] as reference document.

My question concerns the non-existing branches and tags in the linux-socfpga.git repository. Please see screenshot below in red box:

Component: Linux

Git Address: linux-socfpga.git

Branch: socfpga-4.1-ltsi <missing branch>

Tag: ACDS16.1_REL_GSRD_PR <missing tag>

I cloned linux-socfpga.git and tried looking for both the indicated branch and tag for this project but they are nowhere to be found. Can someone give me pointers on how to locate this branch/tag or if there is an alternative branch/tag I can use to make progress on this project ?

thank you.
