The command declaration now uses the new LG-array method to generate list of commands. Thus the __u_boot_cmd section is now superseded and redundant and therefore can be removed. Also, remove externed symbols associated with this section from include/command.h .

======================================== 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
