[U-Boot] [PATCH v5] ARMV7: Add support For Logic OMAP35x/DM37x modules

Peter Barada peter.barada at logicpd.com
Tue Dec 20 06:54:51 CET 2011


This patch adds basic support for OMAP35x/DM37x SOM LV/Torpedo
reference boards. It assumes U-boot is loaded to SDRAM with the
help of another small bootloader (x-load) running from SRAM.

Changes for V5:
    Remove CONFIG_OMAP3_MICRON_DDR - not used anymore
    Trim set_muxconf_regs() to only those different from reset values
    Add 'ramboot' environment commands to load kernel/root-ramdisk via tftp

Changes for V4:
    Use #defines for LAN92XX GPMC register settings
    Add myself to MAINTAINERS
    Fix multiline comments
    Remove switch values in on/off macro definitions
    Modify CONFIG_PREBOOT to make it clear the 4.3" display is the default
    Rework name of GPIO_189 to better describe what its used for
    Fix misc_init_r comment

Changes for V3:
    Inline identify_board() into board_init()
    Remove triple empty lines
    Use sdelay() instead of naked delay loop
    Use enable_gpmc_cs_config() to setup GPMC CS1 access to LAN92xx
    Remove CONFIG_L2_OFF - holdover from previous work in u-boot-2011.06
        where adding 270p 32bpp frambuffer support cause failure while
        booting linux kernel.  Will address when I add video support
    Reduce CONFIG_SYS_MAXARGS to 16

Changes for V2:
    Rework logic_identify() into identify_board() - can't use checkboard()
    	   since its enabled but CONFIG_DISPLAY_BOARDINFO.
    Properly indent comments in set_muxconf_regs()
    Move setup_net_chip() call from misc_init_r to board_eth_init()
    Remove triple empty line spacing
    Pass gpio_request(189) non-empty description
    Remove board/logicpd/omap3som/config.mk
    Remove clean/distclean from board/logicpd/omap3som/Makefile
    Modify board_mmc_init() to be one line function
    Modify include/configs/omap3_logic.h to use on/off #defines
