H A D | irq-gic-v3-its.c | 94100970 Mon Sep 21 15:58:38 CDT 2015 Robert Richter <rrichter@cavium.com> irqchip/gicv3-its: Workaround for Cavium ThunderX errata 22375, 24313
This implements two gicv3-its errata workarounds for ThunderX. Both with small impact affecting only ITS table allocation.
erratum 22375: only alloc 8MB table size erratum 24313: ignore memory access type
The fixes are in ITS initialization and basically ignore memory access type and table size provided by the TYPER and BASER registers.
