ls102xa: etsec: Add etsec support for LS102xA
This patch is to add etsec support for LS102xA. First, Little-endian descriptor mode should be enabled. So RxBDs and TxBDs are interpreted with little-endian byte ordering. Second, TSEC_SIZE and TSEC_MDIO_OFFSET are different from PowerPC, redefine them for LS1021xA. Signed-off-by: Alison Wang <alison.wang@freescale.com>
