It is recommended to check either controller is free to take new spi action. The IP_ACC and AHB_ACC bits indicates that the controller is busy in IP or AHB mode respectively. And the BUSY bit indicates that controller is currently busy handling a transaction to an external flash device Signed-off-by: Suresh Gupta <suresh.gupta@nxp.com> Reviewed-by: Jagan Teki <jagan@openedev.com>
