Subject: rockchip: add weak function symbol called at the beginning of misc_init_r
X-Git-Url: http://git.dujemihanovic.xyz/%22http:/www.sics.se/static/%7B%7B%20.Permalink%20%7D%7D?a=commitdiff_plain;h=7400ed6a1fb81a212aa7144f5caf461d7033ffbd;p=u-boot.git

rockchip: add weak function symbol called at the beginning of misc_init_r

Most Rockchip boards who override misc_init_r do it only to call another
function and keep the rest unchanged. Therefore to allow for less
duplication, let's just add a weak function symbol that is called inside
misc_init_r.
