The interruption support had be removed for ARM architecture and the function udelay_masked() is no more used except in some timer.c files and have the same content than udelay() or __udelay(). This patch update each timer.c implementing this function and remove the associated prototype in u-boot-arm.h. Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com>
