Subject: rockchip: Move the default timer init to a common file
X-Git-Url: http://git.dujemihanovic.xyz/projects?a=commitdiff_plain;h=001b3109da15b0f33fdbcdcfc2e8fada393609dc;p=u-boot.git

rockchip: Move the default timer init to a common file

Rather than repeating the same code in two files (SPL and TPL), move it
to a shared filed.
