Subject: arm: mxs: fix comments in arch_cpu_init to match the code
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=fb9462522991a50b95ea00fdbc495634bb6a7cca;p=u-boot.git

arm: mxs: fix comments in arch_cpu_init to match the code

The comment says to clear the bypass bit, but in fact it sets it, thus
selecting ref_xtal. And the next line of code does not set the divider
to 12, but to (the reset value of) 1.
