[U-Boot-Users] U-boot support arm926ejs

[jack zhao]

Hi,
	Now I am debugging the board which use Marvell 5182 core, which core
is arm9, but I can not seem any information from Serial port. I have traced
the code with GPIO LED port, from that I can seem there are something wrong
in DDR RAM, maybe hardware. Since the arm core use memory to init all the
decide:
init_fnc_t *init_sequence[] = {
        cpu_init,               /* basic cpu dependent setup */
        board_init,             /* basic board dependent setup */
        interrupt_init,         /* set up exceptions */
        env_init,               /* initialize environment */
        init_baudrate,          /* initialze baudrate settings */
        serial_init,            /* serial communications setup */
        console_init_f,         /* stage 1 init of console */
        display_banner,         /* say that we are here */
        dram_init,              /* configure available RAM banks */
#ifndef CONFIG_MARVELL
        display_dram_config,
#endif
#if defined(CONFIG_VCMA9)
        checkboard,
#endif
        NULL,
};
in function start_armboot
But in powerpc the code use DCache to run the init part, so that even if the
ram does not work normally, we can see information from serial port, could
it run in arm core 5182 system. If yes, how to change that.

Could wolf or some other expert answer my questions? Thanks much!
Best Wishes
