From 2d779b39b4e11c4db7a2796af76051e70a556c5f Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Sat, 25 Jul 2015 11:09:11 +0200 Subject: arm: socfpga: system: Clean up pinmux_config.c Implement new accessor, sysmgr_get_pinmux_table(), used to obtain pinmux table and it's size from the QTS-generated pinmux_config.c. The target here is again to get rid of poluting global namespace by including the pinmux_config.h into it. Furthermore, the pinmux_config.h declares some CONFIG_HPS_* macros, which are explicitly useless to us in U-Boot. Instead, U-Boot does use DT to detect exactly these configuration options. This patch makes sure that while this QTS-generated file can stay in the tree, these obscure macros do not ooze into the namespace anymore.
