* [PATCH 2/2] ARM: i.MX: remove __naked from imx*_barebox_entry
  2015-03-04  8:35 [PATCH 1/2] ARM: i.MX: boards: Setup stack before calling imx*_barebox_entry Sascha Hauer

From: Sascha Hauer @ 2015-03-04  8:35 UTC (permalink / raw)
  To: Barebox List

Since the stack is already configured when entering imx*_barebox_entry
we can remove the __naked attribute. This fixes some compilation issues
when some of the imx*_barebox_entry got too complicated to compile without
stack.
