Subject: [POWERPC] Maple: don't override bus-range supplied by firmware
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=59eaef9daef35129a982c9d2b464aacb13349cdf;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

[POWERPC] Maple: don't override bus-range supplied by firmware

This workaround was copy-pasted from the powermac code.  It's not
necessary for maple.
