Ping? Will there be a pull request for soft freeze with this series
included or do I need to do anything with this?

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.
