fsl/85xx, 86xx: Sync up DMA code
The following changes were made to sync up the DMA code between the 85xx and 86xx architectures which will make it easier to break out common 8xxx DMA code: 85xx: - Don't set STRANSINT and SPCIORDER fields in SATR register. These bits only have an affect when the SBPATMU bit is set. - Write 0xffffffff instead of 0xfffffff to clear errors in the DMA status register. We may as well clear all 32 bits of the register... 86xx: - Add CONFIG_SYS_MPC86xx_DMA_ADDR define to address DMA registers - Add clearing of errors in the DMA status register when initializing the controller - Clear the channel start bit in the DMA mode register after a transfer Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
