Subject: Convert loglevel-related kernel boot parameters to early_param
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f6f21c81464ce52dbeec921bdc2e8b288c491920;p=openwrt%2Fstaging%2Fblogic.git

Convert loglevel-related kernel boot parameters to early_param

So we can use them for the early console like console=uart8250 or
earlycon=uart8250 or early_printk
