From f9dfd577dcc8e3173ddce79bca535eeee0fad1a4 Mon Sep 17 00:00:00 2001 From: Phil Elwell Date: Tue, 2 Jul 2019 17:13:05 +0100 Subject: [PATCH] arm: dts: Add coherent_pool=1M to Pi 4 bootargs Downstream Raspberry Pi dts files add "coherent_pool=1M" to the kernel command line to aid the dwc_otg driver, but this excluded Pi 4 which uses a new XCHI interface instead. UAS also benefits from a larger coherent_pool value, so replicate the addition in bcm2711-rpi-4-b.dts.
