Subject: ppc64 iSeries: Move memory setup into iSeries device tree
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3ab42407fe0628c7880b21eff057566390865319;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ppc64 iSeries: Move memory setup into iSeries device tree

This patch adds the required nodes to the iSeries device tree to allow
early_init_devtree() to do the lmb setup for us.
