From 06954b6a9e6a303b4782d543f5299b3b4020fd1f Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Fri, 11 Feb 2022 23:32:38 +0100 Subject: [PATCH] ARM: ixp4xx: Convert to SPARSE_IRQ and P2V Turn on sparse IRQs and patch-physical-to-virtual for IXP4xx as this is required for multiplatform. Drop the PHYS_OFFSET as we are now using P2V. Tested and works like a charm on my systems.
