[PATCH 1/2] ARM: tegra: remove Whistler support

Stephen Warren swarren at wwwdotorg.org
Thu Apr 13 14:55:58 EDT 2017


From: Stephen Warren <swarren at nvidia.com>

Whistler is an ancient Tegra 2 reference board. I may have been the only
person who ever used it with upstream software, and I've just recycled
the board hardware. Hence, it makes sense to remove support from software.
