This patch removes interrupt priority tables from the intc code. Optimal priority assignment varies with embedded application anyway, so keeping the interrupt priority tables together with cpu-specific code doesn't make sense. The function intc_set_priority() should be used instead to set the desired interrupt priority level. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
