Since there is only 1G memory in Panda, the physical address is from 0x0
to 0x3FFFFFFF. If you try to mmap fixed address from this arrange, it
will works. But for upper 1G memory mapping, it will give you other
virtual address.
Try this loop:
--
for(i=0x30000000;i<0x40010000;i+=0x10000)
--
It will report only the last mapping is different:
--
ubu...@omap:~$ ./mmap_test
0x40000000: 0x40084000 0
--
So I still think this bug is invalidate.
