[PATCH] ARM: imx: allow support to be disabled

[PATCH] ARM: imx: allow support to be disabled

[Stephen Warren]

From: Stephen Warren <swarren@nvidia.com>

Since ARCH_MXC's Kconfig option has no string name, the user is never
presented with an option to enable/disable this setting. Rather, it is
automatically enabled based on the conditions in the def_bool entry.

Add a string, so that the user gets to choose whether to enable ARCH_MXC,
and rename the i.MX options menu so that it doesn't clash. Also, change
from "def_bool y" to "bool" to be more consistent with other machines.

Note that if Tegra and i.MX support are enabled at the same time, then
the build will fail since both Tegra's and i.MX's head.S define symbol
v7_invalidate_l1. shmobile appears to have the same conflict. Note that
patches to port Tegra to ARCH_MULTI aren't yet in linux-next, but I can
point anyone who's interested at my github tree.

Thanks for the patch, Stephen.  I have queued a similar fix [1] from
Fabio.  Hopefully, arm-soc folks will apply it soon.
