Communication Resources

Join IRC channel at "#spacemit" of Libera.chat
Join spacemit@lists.linux.dev mailing list for discussion

The two branches below will accept patches which sent to U-Boot git tree, and eventually included into upstream U-Boot.

fixes: For collecting critical bug fixes
for-next: For accepting new features, usually it's a branch merged with various subsystem patches
- Note: it will be forced pushed regularly!

The branch starting with 'k1/' or 'k3/' prefix are used for individual feature or testing only, it's not a stable or permanent branch.
