I recently decided to try getting an arm build of 10.0-CURRENT
(r243319) (TARGET=arm KERNCONF=GUMSTIX-QEMU) running inside a
Qemu-emulated Gumstix Verdex board, using qemu-devel (1.1.1) as the
emulator.

The problem appears to be FreeBSD auto-detecting twice the emulated
available RAM. Does this ring any bells with anyone? My google-fu
has so far failed me.

From quick glance it seems that FreeBSD's SDRAM size detection code
thinks that there are 4 banks of 128Mb. While the same MDCNFG
register value(0x8ad30ad3) is used in U-Boot source to indicate 256Mb
memory size. So I assume our code is broken for PXA270. If anybody
got a datasheet for it - please take a look, or send datasheet my
way.
I will admit to not knowing much about the kernel's internals, so I hope
someone gets in touch with you regarding the PXA270's datasheet. I'll happily
be a test-subject for any patches that might arise!
cheers,
gja
