-Renesas R0P7757LC0030RL board
-========================================
-
-This board specification:
-=========================
-
-The R0P7757LC0030RL(board config name:sh7757lcr) has the following device:
-
- - SH7757 (SH-4A)
- - DDR3-SDRAM 256MB (with ECC)
- - SPI ROM 8MB
- - 2D Graphic controller
- - Ethernet controller
- - eMMC 2GB
-
-
-configuration for This board:
-=============================
-
-You can select the configuration as follows:
-
- - make sh7785lcr_config
-
-
-This board specific command:
-============================
-
-This board has the following its specific command:
-
- - sh_g200
- - write_mac
-
-
-1. sh_g200
-
-If we run this command, SH4 can control the G200.
-The default setting is that SH4 cannot control the G200.
-
-
-2. write_mac
-
-You can write MAC address to SPI ROM.
-
- Usage 1) Write MAC address
-
-   write_mac [ETHERC ch0] [ETHERC ch1] [GETHERC ch0] [GETHERC ch1]
-
-	For example)
-	 => write_mac 00:00:87:6c:21:80 00:00:87:6c:21:81 00:00:87:6c:21:82 00:00:87:6c:21:83
-		*) 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
-		 ETHERC ch0 = 00:00:87:6c:21:80
-		 ETHERC ch1 = 00:00:87:6c:21:81
-		GETHERC ch0 = 00:00:87:6c:21:82
-		GETHERC ch1 = 00:00:87:6c:21:83
-
-
-Update SPI ROM:
-============================
-
-1. Copy u-boot image to RAM area.
-2. Probe SPI device.
-   => sf probe 0
-   8192 KiB M25P64 at 0:0 is now current device
-3. Erase SPI ROM.
-   => sf erase 0 80000
-4. Write u-boot image to SPI ROM.
-   => sf write 0x89000000 0 80000
