[U-Boot] [PATCH v4 09/19] SPEAr : macb driver support added for spear310 and spear320

[Vipin KUMAR]

From: Vipin KUMAR <vipin.kumar at st.com>

SPEAr310 and SPEAr320 SoCs have an extra ethernet controller. The
driver for this device is already supported by u-boot, so configuring
board configuration file and defining base addresses etc to make use
of the common driver
