This patch series adds support for CompuLab CL-SOM-AM57X board and the
SBC-AM57X evaluation kit.

CL-SOM-AM57x is a miniature System-on-Module (SoM) based on
TI Sitara AM57x ARM Cortex-A15 System-on-Chip family.

SBC-AM57x is a single board computer, implemented with the
CL-SOM-AM57x computer-on-module and the SB-SOM-AM57x carrier board.
The CL-SOM-AM57x providing most of the functions and the SB-SOM-AM57x providing
additional peripheral functions and connectors.

The SBC-AM57x has the following features:


CPU:		Texas Instruments Sitara AM5728 dual-core ARM Cortex-A15, 1.5GHz or
		Texas Instruments Sitara AM5718 single-core ARM Cortex-A15, 1.5GHz

RAM:		DDR3, 512MB ? 4GB

Storage:	NAND flash, 512MB - 1GB or eMMC flash, 4GB - 32GB
		SPI-flash 2MB

Ethernet:	Up to 2x 10/100/1000Mbps Ethernet ports (MAC+PHY)

WiFi/BT:	802.11b/g/n WiFi interface (TI WiLink 8 WL1801 chipset) or
		Dual-band 2x2 802.11a/b/g/n WiFi interface (TI WiLink 8 WL1837 chipset)

Analog Audio:	Audio codec with stereo output, stereo input and microphone support

Features supported :

* Serial console
* SPI Flash
* MMC/SD Card
* eMMC storage
* SATA
* PCA9555 - GPIO expander over I2C5 bus
* USB

Use spl alternate boot device feature to define fallback to
the main boot device as it is defined by hardware.

Add MAC support.

Use PHY, connected to RGMII1 as a default Eth adapter,
by appropriate setting of 'cpsw_data.active_slave'.

'cpsw_phy' env variable can override this setting.

Set the MAC addresses in the U-Boot environment.
The addresses are retrieved from the on-board EEPROM or from the SOC's
MAC fuses.

Set the following PHYs RGMII clock delays:
- Enable RX delay
- Disable TX delay
