[U-Boot] use CONFIG_PRE_CONSOLE_BUFFER

[Johann Obermayr]

Hello,

i will use CONFIG_PRE_CONSOLE_BUFFER and have some trouble.

myboard.h
    #define CONFIG_PRE_CONSOLE_BUFFER
    #define CONFIG_PRE_CON_BUF_SZ            4096
    #ifndef __ASSEMBLY__
    extern char preConsoleBuffer[] __attribute__ ((section(".data")));
    #define CONFIG_PRE_CON_BUF_ADDR            preConsoleBuffer
    #endif

myboard.c
    char preConsoleBuffer[ CONFIG_PRE_CON_BUF_SZ ] __attribute__ 
((section(".data")));


    int board_init()
    {
    .....
    console_init_f();
    .....
    }

u-boot/arch/arm/lib/board.c
    remove console_init_f(); from init_sequence list.

after this changes, u-boot will hang.

use u-boot v2013-04 on arm i.mx6 (Freescale)

Best Regards
  Johann
