Subject: imx8m: evk: spl: probe clk in spl early stage
X-Git-Url: http://git.dujemihanovic.xyz/img/sics.gif?a=commitdiff_plain;h=1a9971035dde36e59e2a2e2f50668eebdf63d9d1;p=u-boot.git

imx8m: evk: spl: probe clk in spl early stage

We are going to add i2c pmic support before dram could be used.
So we need enable clk driver earlier, so use spl_early_init
and move clock controller probe eariler to board_init_f.
