Communication Resources

• Join IRC channel at "#spacemit" of Libera.chat
• Join spacemit@lists.linux.dev mailing list for discussion
  • send subscription to spacemit+subscribe@lists.linux.dev if want to participate

Branch Management

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.
