I believe the sunxi EMAC uses SRAM and that the current sxie(4) driver
expects that SRAM to be properly initialized and set up by U-Boot.
In sunxi_emac_board_setup() U-Boot does:
/* Map SRAM to EMAC */
setbits_le32(&sram->ctrl1, 0x5 << 2);
Not sure if that is all that is needed. Doing that from inside the
sxie(4) driver code is a bit hard; this would probably require adding
a driver for the sram-controller ("allwinner,sun4i-a10-sram-controller").
Cheers,
