We have switched to Kconfig and the boards.cfg file is going to be removed. We have to retrieve the board status and maintainers information from it. The MAINTAINERS format as in Linux Kernel would be nice because we can crib the scripts/get_maintainer.pl script. After some discussion, we chose to put a MAINTAINERS file under each board directory, not the top-level one because we want to collect relevant information for a board into a single place. TODO: Modify get_maintainer.pl to scan multiple MAINTAINERS files.

======================================== Renesas Technology R0P7785LC0011RL board ======================================== This board specification: ========================= The R0P7785LC0011RL(board config name:sh7785lcr) has the following device: - SH7785 (SH-4A) - DDR2-SDRAM 512MB - NOR Flash 64MB - 2D Graphic controller - SATA controller - Ethernet controller - USB host/peripheral controller - SD controller - I2C controller - RTC This board has 2 physical memory maps. It can be changed with DIP switch(S2-5). phys address | S2-5 = OFF | S2-5 = ON -------------------------------+---------------+--------------- 0x00000000 - 0x03ffffff(CS0) | NOR Flash | NOR Flash 0x04000000 - 0x05ffffff(CS1) | PLD | PLD 0x06000000 - 0x07ffffff(CS1) | reserved | I2C 0x08000000 - 0x0bffffff(CS2) | USB | DDR SDRAM 0x0c000000 - 0x0fffffff(CS3) | SD | DDR SDRAM 0x10000000 - 0x13ffffff(CS4) | SM107 | SM107 0x14000000 - 0x17ffffff(CS5) | I2C | USB 0x18000000 - 0x1bffffff(CS6) | reserved | SD 0x40000000 - 0x5fffffff | DDR SDRAM | (cannot use) configuration for This board: ============================= You can choose configuration as follows: - make sh7785lcr_config - make sh7785lcr_32bit_config When you use "make sh7785lcr_config", there is build U-Boot for 29-bit address mode. This mode can use 128MB DDR-SDRAM. When you use "make sh7785lcr_32bit_config", there is build U-Boot for 32-bit extended address mode. This mode can use 384MB DDR-SDRAM. And if you run "pmb" command, this mode can use 512MB DDR-SDRAM. * 32-bit extended address mode PMB mapping * a) on start-up virt | phys | size | device -------------+---------------+---------------+--------------- 0x88000000 | 0x48000000 | 384MB | DDR-SDRAM (Cacheable) 0xa0000000 | 0x00000000 | 64MB | NOR Flash 0xa4000000 | 0x04000000 | 16MB | PLD 0xa6000000 | 0x08000000 | 16MB | USB 0xa8000000 | 0x48000000 | 384MB | DDR-SDRAM (Non-cacheable) b) after "pmb" command virt | phys | size | device -------------+---------------+---------------+--------------- 0x80000000 | 0x40000000 | 512MB | DDR-SDRAM (Cacheable) 0xa0000000 | 0x40000000 | 512MB | DDR-SDRAM (Non-cacheable) This board specific command: ============================ This board has the following its specific command: - hwtest - printmac - setmac - pmb (sh7785lcr_32bit_config only) 1. hwtest This is self-check command. This command has the following options: - all : test all hardware - pld : output PLD version - led : turn on LEDs - dipsw : test DIP switch - sm107 : output SM107 version - net : check RTL8110 ID - sata : check SiI3512 ID - net : output PCI slot device ID i.e) => hwtest led turn on LEDs 3, 5, 7, 9 turn on LEDs 4, 6, 8, 10 => hwtest net Ethernet OK 2. printmac This command outputs MAC address of this board. i.e) => printmac MAC = 00:00:87:**:**:** 3. setmac This command writes MAC address of this board. i.e) => setmac 00:00:87:**:**:** 4. pmb This command change PMB for DDR-SDRAM all mapping. However you cannot use NOR Flash and USB Host on U-Boot when you run this command. i.e) => pmb
