Subject: video i.MX: remove mx1 compile time dependencies
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f142b6196891660b329408e71573f97475823667;p=openwrt%2Fstaging%2Fblogic.git

video i.MX: remove mx1 compile time dependencies

remove usage of CONFIG_ARCH_MX1. It's mostly unused anyway, replace
it with cpu_is_mx1() where necessary. Also, depend on
IMX_HAVE_PLATFORM_IMX_FB instead of the architectures directly.
