2017-05-11arm: Correct signature for get_ticks()Simon Glass
This should be uint64_t to match its definition in common.h. Fix it. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-11-05armv8: define get_ticks() for the ARMv8 Generic TimerAndre Przywara
For 64-bit ARM systems we provide just a timer_read_counter() implementation and rely on the generic non-uclass get_ticks() function in lib/time.c to call the former. However this function is actually not 64-bit safe, as it assumes a "long" to be 32-bit. Beside the fact that the resulting uint64_t isn't bigger than "long" on 64-bit architectures and thus combining two counters makes no sense, we get all kind of weird results when we try to OR in the high value shifted by _32_ bits. So let's avoid that function at all and provide a straight forward get_ticks() implementation for ARMv8, which also is in line with ARMv7. This fixes occasional immediate time-out expiration issues I see on the Pine64 board. The root cause of this needs to be investigated, but this fix looks like the right thing anyway.
