Subject: [PULL 16/37] hw/riscv/sifive_u: use 'fdt' from MachineState
Date: Fri, 20 Jan 2023 17:38:52 +1000	[thread overview]
Message-ID: <20230120073913.1028407-17-alistair.francis@opensource.wdc.com> (raw)
In-Reply-To: <20230120073913.1028407-1-alistair.francis@opensource.wdc.com>

From: Daniel Henrique Barboza <dbarboza@ventanamicro.com>

The MachineState object provides a 'fdt' pointer that is already being
used by other RISC-V machines, and it's also used by the 'dumpdtb' QMP
command.

Remove the 'fdt' pointer from SiFiveUState and use MachineState::fdt
instead.
