* this compile option actually turns on a command, so name it
  accordingly
* also move the Kconfig definition into commands/Kconfig, thus
  placing getopt into the "Network commands" section
* while at it, improve Kconfig documention

detect the cpu model to dynamise the periphs mapping

currently only tested on qemu but should work on real hardware

Cortex-A9

if you use 1GiB of ram you can run the same barebox on Cortex-A15 or Cortex-A9
otherwise use vexpress_ca9_defconfig where the TEXT_BASE is at 0x63f00000

when we will add the relocation support this defconfig will be drop

qemu/arm-softmmu/qemu-system-arm -M vexpress-a9 -m 1024 -smp 1 -kernel build/vexpress/barebox -pflash build/vexpress/flash0 -nographic

Cortex-A15
