# \[PATCH 1/8\] ARM: OMAP2+: Move DISPC L3 firewall to happen in omap\_display\_init() - From: Tony Lindgren \ - Date: 2012-02-21 23:40:35 - List: linux-fbdev - Page: https://ratatoskr.run/linux-fbdev/2012/02/8597714 - Thread: https://ratatoskr.run/linux-arm-kernel/2012/02/8597713/t.md ```text Otherwise we cannot move most of plat/io.h to be a local iomap.h for mach-omap2.
