Fork of the vendor (Boundary Devices) u-boot for Reform 2, with minor tweaks. The goal is to migrate to mainstream u-boot or barebox ASAP. The main impediment so far is the 4GB RAM config.

  26. # to get the ordering right.
  27. #
  28. # Most importantly: sub-Makefiles should only ever modify files in
  29. # their own directory. If in some directory we have a dependency on
  30. # a file in another dir (which doesn't happen often, but it's often
  31. # unavoidable when linking the built-in.o targets which finally
  32. # turn into vmlinux), we will call a sub make in that other dir, and
  33. # after that we are sure that everything which is in that other dir
  34. # is now up to date.
  35. #
  36. # The only cases where we need to modify files which have global
  37. # effects are thus separated out and done before the recursive
  38. # descending is started. They are now explicitly listed as the
