Subject: arm: imx: Drop custom lowlevel_init
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=ae237b1e62d9f97125990c09d3320d853bb70412;p=u-boot.git

arm: imx: Drop custom lowlevel_init

The custom lowlevel_init implementation is no longer necessary, since
it is responsible for routing and trapping SErrors in U-Boot in EL2,
which is implemented in common code since commit:
6c7691edd55 ("armv8: Always unmask SErrors")
