Emulation of armv7+e1000e+/dev/sda or /dev/mmcblk0 devices

[steve freyder]

Greetings qemu-arm group,


I'm a new qemu-arm list member and looking to get an emulation of an 
armv7 processor with a PCI bus, supporting an e1000e NIC, and some form 
of storage device preferably SATA and [e]MMC - I have an iMX6 SOM custom 
board with an e1000e on the carrier board via PCI that I'm attempting to 
approximate.  I want to boot U-Boot (I've built U-Boot 5.2 with support 
for MMC, SATA, and e100e networking).  I have the "virt" machine able to 
boot U-Boot and see the e1000e, but I have found nothing that allows the 
booted U-Boot see any MMC or SATA devices.  All attempts to use -sd, or 
-drive to create some kind of MMC/SATA device have failed with what 
appear to be (as I have been able to understand) the standard reasons, 
missing busses, missing properties, etc, etc. A majority of searches 
result in documentation from developers that's 5-10 or more years old, 
so I'm hard-pressed to determine whether this is my own lack of 
knowledge (probably YES), or whether I'm simply looking at stuff that's 
been overcome by events.


I apologize in advance if this is not the proper forum for this, and 
will happily take this to a different forum, but is there any chance 
someone could give me a clue about the right way to look at all of this, 
and whether there's any machine or system definition out there that 
would support (or be a starting point for supporting) what I'm looking for.


Thanks in advance,

Steve
