Joe Hershberger fb8977c5be net: Always build the string_to_enetaddr() helper Part of the env cleanup moved this out of the environment code and into the net code. However, this helper is sometimes needed even when the net stack isn't included. Move the helper to lib/net_utils.c like it's similarly-purposed string_to_ip(). Also rename the moved function to similar naming. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Reported-by: Ondrej Jirman <megous@megous.com>		2019-12-09 09:47:41 -06:00

========================================
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 sh7757lcr_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
