The eMMC issue is on the raspi4.
Looking at my notes, I used "root=/dev/mmcblk0 rootwait", and it hangs with:

Waiting for root device /dev/mmcblk0...
[    0.898870] mmc-bcm2835 3f300000.mmc: mmc_debug:0 mmc_debug2:0
[    0.901397] mmc-bcm2835 3f300000.mmc: DMA channel allocated
[    0.930041] sdhost: log_buf @ (ptrval) (fac53000)
[    0.969910] mmc1: queuing unknown CIS tuple 0x80 (2 bytes)
[    0.973894] mmc1: queuing unknown CIS tuple 0x80 (3 bytes)
[    0.977753] mmc1: queuing unknown CIS tuple 0x80 (3 bytes)
[    0.981228] mmc0: sdhost-bcm2835 loaded - DMA enabled (>1)

So I guess now Linux improved and use new features not covered by our
hw/sd/bcm2835_sdhost.c model :(
(I have to use recent Linux kernels because older don't support the raspi4).

I'll keep you informed, thanks for the hint!

Phil.
