This driver is actually used for powerpc and m68k/ColdFire.
On ColdFire SoC's, interrupt flag get not set if IIEN flag (mbcr bit6, interrupt enabled) is not set appropriately before each transfert. As a result, the transfert hangs forever waiting for IIEN. This patch set IIEN before each transfert, while considering this fix as not harming powerpc arch.
