This fixes building in automated flow that doesn't use defconfigs. See discussion on that topic here: http://patchwork.ozlabs.org/patch/502558/ See similar patches for other architectures/platforms here: [1] http://git.denx.de/?p=u-boot.git;a=commit;h=ff560a13056a565a4e9ce1761bd04276a3cace88 [2] http://git.denx.de/?p=u-boot.git;a=commit;h=589907e2c187ec69b351c38ccda36730d25ab5d6 And while at it add missing shell prompt to axs103.

Starting with ARC700 4.9, Cache line length is configurable,
|
|
This option specifies "N", with Line-len = 2 power N
|
|
So line lengths of 32, 64, 128 are specified by 5,6,7, respectively
|
|
Linux only supports same line lengths for I and D caches.
