6934f15b22 hw/riscv: remove 'fdt' param from riscv_setup_rom_reset_vec()
The 'fdt' param is not being used in riscv_setup_rom_reset_vec().
Simplify the API by removing it. While we're at it, remove the redundant
'return' statement at the end of function.

56917307f4 hw/riscv: shakti_c: Use MachineState::ram and MachineClass::default_ram_id
Using memory_region_init_ram(), which can't possibly handle vhost-user,
and can't work as expected with '-numa node,memdev' options.

Use MachineState::ram instead of manually initializing RAM memory
region, as well as by providing MachineClass::default_ram_id to
opt in to memdev scheme.

b8fb878aa2 hw/intc: Upgrade the SiFive CLINT implementation to RISC-V ACLINT
The RISC-V ACLINT is more modular and backward compatible with
original SiFive CLINT so instead of duplicating the original
SiFive CLINT implementation we upgrade the current SiFive CLINT
implementation to RISC-V ACLINT implementation.

Instead of using riscv_cpu_update_mip() let's instead use the new RISC-V
CPU GPIO lines to set the external MIP bits.
