2022-10-27mips/malta: pass RNG seed via env var and re-randomize on rebootJason A. Donenfeld
As of the kernel commit linked below, Linux ingests an RNG seed passed as part of the environment block by the bootloader or firmware. This mechanism works across all different environment block types, generically, which pass some block via the second firmware argument. On malta, this has been tested to work when passed as an argument from U-Boot's linux_env_set. As is the case on most other architectures (such as boston), when booting with `-kernel`, QEMU, acting as the bootloader, should pass the RNG seed, so that the machine has good entropy for Linux to consume. So this commit implements that quite simply by using the guest random API, which is what is used on nearly all other archs too. It also reinitializes the seed on reboot, so that it is always fresh.

2022-06-11hw/block/fdc-sysbus: Always mark sysbus floppy controllers as not having DMAPeter Maydell
The sysbus floppy controllers (devices sysbus-fdc and sun-fdtwo) don't support DMA. The core floppy controller code expects this to be indicated by setting FDCtrl::dma_chann to -1. This used to be done in the device instance_init functions sysbus_fdc_initfn() and sun4m_fdc_initfn(), but in commit 1430759ec3e we refactored this code and accidentally lost the setting of dma_chann. For sysbus-fdc this has no ill effects because we were redundantly also setting dma_chann in fdctrl_init_sysbus(), but for sun-fdtwo this means that guests which try to enable DMA on the floppy controller will cause QEMU to crash because FDCtrl::dma is NULL. Set dma_chann to -1 in the common instance init, and remove the redundant code in fdctrl_init_sysbus() that is also setting it. There is a six-year-old FIXME comment in the jazz board code to the effect that in theory it should support doing DMA via a custom DMA controller. If anybody ever chooses to fix that they can do it by adding support for setting both FDCtrl::dma_chann and FDCtrl::dma. (A QOM link property 'dma-controller' on the sysbus device which can be set to an instance of IsaDmaClass is probably the way to go.)

If the vga flag is passed in the command line "default_vga"(declared in softmmu/vl.c) variable is set to 0. To warn user, the condition checks if vga_interface_created is false and default_vga is equal to 0. If "-vga none" is passed, this patch will not warn the user regarding the creation of VGA device. The warning "A -vga option was passed but this machine type does not use that option; no VGA device has been created" is logged if vga flag is passed but no vga device is created.
