Hi,
I am working on getting FreeBSD to boot on a new ARM based board,
and am hitting this issue any time I load a driver for the PCI based
devices on the board.
My current code can be found here:

Hi Tom,
My guess is, you should include std.i80219 instead of std.i80321 in
std.em7210.
If you do not, CPU_XSCALE_80219 won't be defined, and the 80321 code to
check if the board is host or not will be used, and will wrongly
assume it is not, and thus won't map the PCI mem correctly.
Hi Olivier,
I have switched out the std file and am now using std.i80219 but am
still having issues.
I think the problems are the pci memory mappings in the controller
devices.
On linux em0 gets mapped as follows:
cd 0000\:00\:01.0/
# ls
class device local_cpus subsystem_device
config driver resource subsystem_vendor
detach_state irq rom vendor
# cat resource
0x0000000080000000 0x000000008001ffff 0x0000000000000200

Where as on FreeBSD I am seeing this:
em0: <Intel(R) PRO/1000 Network Connection 6.9.14> port
0xfe400000-0xfe40003f mem 0-0x1ffff,0x20000-0x3ffff irq 29 at device
1.0 on pci0
Seems that I am missing the 0x800 off the front of the PCI memory
mappings.
I have confirmed this with the ata driver also and see the same issues.
Where should I be looking to fix this?
Forgot to include the output from VERBOSE_INIT_ARM
