From ac1a474d71d6cbf94bf26889da5768f5f2b0ca2b Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Thu, 15 Apr 2010 13:32:58 -0700 Subject: libertas: Davinci platforms need more time loading helper firmware Davinci platforms apparently need more time in-between helper firmware blocks. Even though this is an increased delay, we only take this hit once at initialization time. Signed-off-by: Dan Williams Signed-off-by: John W.
