Subject: ARM: tegra: move ft_system_setup()
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=9889862545a0de2e6cf0fdf6171412cafc46c218;p=u-boot.git

ARM: tegra: move ft_system_setup()

Currently, ft_system_setup() is implemented by board*.c, which are a bit
of a dumping ground for a bunch of unrelated functionality, and separate
versions exist for pre-Tegra186 and Tegra186. Move the implementation into
a separate file to separate functionality, and allow sharing.
