2020-01-17common: Move hang() to the same header as panic()Simon Glass
At present panic() is in the vsprintf.h header file. That does not seem like an obvious choice for hang(), even though it relates to panic(). So let's put hang() in its own header.

2019-05-05dm: cache: add the pl310 cache controller driverDinh Nguyen
Add a PL310 cache controller driver that is usually found on ARMv7(32-bit) devices. The driver configures the cache settings that can be found in the device tree files. This initial revision only configures basic settings(data & instruction prefetch, shared-override, data & tag latency). I believe these are the settings that affect performance the most. Comprehensive settings can be done by the OS. Reviewed-by: Simon Glass <sjg@chromium.org> Signed-off-by: Dinh Nguyen <dinguyen@kernel.org>
