-Renesas SH7753 EVB board
-========================================
-
-This board specification:
-=========================
-
-The SH7753 EVB (board config name:sh7753evb) has the following device:
-
- - SH7753 (SH-4A)
- - DDR3-SDRAM 512MB
- - SPI ROM 8MB
- - Gigabit Ethernet controllers
- - eMMC 4GB
-
-
-Configuration for This board:
-=============================
-
-You can select the configuration as follows:
-
- - make sh7753evb_config
-
-
-This board specific command:
-============================
-
-This board has the following its specific command:
-
- - write_mac
-
-
-1. write_mac
-
-You can write MAC address to SPI ROM.
-
- Usage 1) Write MAC address
-
-   write_mac [GETHERC ch0] [GETHERC ch1]
-
-	For example)
-	 => write_mac 74:90:50:00:33:9e 74:90:50:00:33:9f
-		*) We have to input the command as a single line
-		   (without carriage return)
-		*) We have to reset after input the command.
-
- Usage 2) Show current data
-
-   write_mac
-
-	For example)
-		=> write_mac
-		GETHERC ch0 = 74:90:50:00:33:9e
