+Subject: [PATCH 04/29] spi: mtk_spim: clear IRQ enable bits
+
+In u-boot we don't use IRQ. Instead, we poll busy bit in SPI_STATUS.
+
+However these IRQ enable bits may be set in previous boot stage (BootROM).
+
+If we leave these bits not cleared, although u-boot has disabled IRQ and
+nothing will happen, the linux kernel may encounter panic during
+initializing the spim driver due to IRQ event happens before IRQ handler
+is properly setup.
+
+This patch clear IRQ bits to prevent this from happening.
