Hello, This series adds NVRAM and support for -kernel, -initrd and -append options to the amigaone machine. This makes it easier to boot AmigaOS and avoids a crash in the guest when it tries to access NVRAM.
While the -kernel option emulates what U-Boot passes to the kernel, old Linux kernels for amigaone may not work with it because of two reasons: these come in legacy U-Boot Multi-File image format that QEMU cannot read and even after unpacking that and creating a kernel uimage it won't find PCI devices because it does not initialise them correctly. This works when booted from U-Boot because U-Boot inits PCI devices. So does my BBoot loader which can be used to load AmigaOS so I don't intend to emulate that part of U-Boot. I'd like this to be merged for the next release please. When merging please update https://wiki.qemu.org/ChangeLog/10.0 with the following: amigaone Added support for NVRAM and -kernel, -initrd, -append command line options. By default the NVRAM contents are not preserved between sessions. To make it persistent create a backing file with 'qemu-image create -f raw nvram.bin 4k' and add -drive if=mtd,format=raw,file=nvram.bin to keep NVRAM contents in the backing file so settings stored in it will be preserved between sessions. To run AmigaOS with BBoot using the -kernel option at least BBoot version 0.8 is needed. Older BBoot versions only work with -device loader and cannot be used with -kernel on amigaone.
