Subject: [PULL 12/32] hw/riscv/boot.c: calculate fdt size after fdt_pack()
Date: Tue, 7 Feb 2023 17:09:23 +1000 [thread overview]
Message-ID: <20230207070943.2558857-13-alistair.francis@opensource.wdc.com> (raw)
In-Reply-To: <20230207070943.2558857-1-alistair.francis@opensource.wdc.com>
From: Daniel Henrique Barboza <dbarboza@ventanamicro.com>
fdt_pack() can change the fdt size, meaning that fdt_totalsize() can
contain a now deprecated (bigger) value.
