The R0P7752C00000RZ(board config name:sh7752evb) has the following device:

 - SH7752 (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 sh7752evb_config


This board specific command:
============================

This board has the following its specific command:

 - 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

		=> write_mac
		GETHERC ch0 = 74:90:50:00:33:9e
		GETHERC ch1 = 74:90:50:00:33:9f


Update SPI ROM:
============================

1. Copy u-boot image to RAM area.
2. Probe SPI device.
   => sf probe 0
   SF: Detected MX25L6405D with page size 64KiB, total 8 MiB
3. Erase SPI ROM.
   => sf erase 0 80000
4. Write u-boot image to SPI ROM.
   => sf write 0x48000000 0 80000
