[PATCH 19/22] ARM: shmobile: Make EMEV2 platform devices more compact

Simon Horman horms+renesas at verge.net.au
Wed Jul 17 19:31:58 EDT 2013


From: Magnus Damm <damm at opensource.se>

Convert the EMEV2 SoC device setup code from using very
verbose resources and static platform devices to the
same style as more recent boards. This reduces the size
of the code.
