From 487d73fc470d233f2d5da9cec7cd229ae8b88b49 Mon Sep 17 00:00:00 2001 From: Daniel Henrique Barboza Date: Mon, 6 Feb 2023 11:00:21 -0300 Subject: hw/riscv/boot.c: consolidate all kernel init in riscv_load_kernel() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The microchip_icicle_kit, sifive_u, spike and virt boards are now doing the same steps when '-kernel' is used: - execute load_kernel() - load init_rd() - write kernel_cmdline Let's fold everything inside riscv_load_kernel() to avoid code repetition. To not change the behavior of boards that aren't calling riscv_load_init(), add an 'load_initrd' flag to riscv_load_kernel() and allow these boards to opt out from initrd loading.
