[U-Boot] [PATCH v2 1/2] patman: Cache the CC list from MakeCcFile() for use in ShowActions()

Doug Anderson dianders at chromium.org
Tue Dec 4 01:40:42 CET 2012


Currently we go through and generate the CC list for patches twice.
This gets slow when (in a future CL) we add a call to
get_maintainer.pl on Linux.  Instead of doing things twice, just cache
the CC list when it is first generated.
