OK, so I changed Russel's printk to the following way:
+printk("vmalloc: mapping page %p (0x%08lx000) at 0x%08lx 0x%08zx\n", + page, page_to_pfn(page), addr, __pa(addr));
(added __pa(addr)) and now I hope I am seeing the physical addresses at the last column:
[ 19.023836] vmalloc: mapping page ef7f1fa0 (0x000bfc7d000) at 0xf04a3000 0x304a3000 [ 19.031515] vmalloc: mapping page ef7f3360 (0x000bfd1b000) at 0xf04a4000 0x304a4000 [ 19.039221] vmalloc: mapping page ef7f18e0 (0x000bfc47000) at 0xf04a5000 0x304a5000
and they do not exceed mem= option. Not sure though if this was the right thing to do though. :)
Anyway, with mem=0xc000000 it seems to boot, so many thanks to everyone!
I'll check the value of the register 0xf1020254 tomorrow and will post back.
