With this patch I get the following warning on a 64bit host:

drivers/base/driver.c: In function ‘do_devinfo’:
drivers/base/driver.c:353:11: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
drivers/base/driver.c:353:31: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]

We should probably set CONFIG_PHYS_ADDR_T_64BIT correctly on a 64bit
host.
