This also changes shared_mem to use all the remaining RAM, instead of
reserving a fixed-size buffer.

We can clear the reset cause in system pre-init now because of a
previous change which preserves it across a sysjump.

Add a host command returning chip information. The interface is in common/

1) Use 'reboot' command from console to boot image. Should end up in
image A, with last reset reason soft cold. 'sysinfo' should show we
jumped to this image.
2) sysjump RO. Should end up in RO; otherwise same as 1)
3) reboot using Power+Esc+Reload. Should end up in image RO, with last
reset reason reset pin. 'sysinfo' should show we did not jump to this
image.
4) sysjump A. Should end up in A with reset reason reset pin.
'sysinfo' should show we jumped here.

Comapre the range to be write (erase) with the range of active image.
If overlap, return error to indicate the access denied.
Note that we actually protect only runtime code and ro data.
FMAP is intentional unprotected so that flashrom can update to new map
before jumping. Since the vector table and init code are in the same
erase page, they are unprotected as well.
