From 190e0ae6290d17780c075ca38b9ecb9895dee419 Mon Sep 17 00:00:00 2001 From: Daniel Henrique Barboza Date: Fri, 31 May 2024 17:27:52 -0300 Subject: [PATCH] hw/riscv/virt.c: add address-cells in create_fdt_one_aplic() We need #address-cells properties in all interrupt controllers that are referred by an interrupt-map [1]. For the RISC-V machine, both PLIC and APLIC controllers must have this property. PLIC already sets it in create_fdt_socket_plic(). Set the property for APLIC in create_fdt_one_aplic().
