From 4f1572d6f191f4618b30be3fda7344461910a03f Mon Sep 17 00:00:00 2001 From: Joel Stanley Date: Wed, 4 Jun 2025 12:24:45 +0930 Subject: [PATCH] hw/riscv/virt: Use setprop_sized_cells for uart The current device tree property uses two cells for the address (and for the size), but assumes the they are less than 32 bits by hard coding the high cell to zero. Use qemu_fdt_setprop_sized_cells to do the job of splitting the upper and lower 32 bits across cells.
