Re: How controll is passed from uboot to kernel

[Peter Teoh <htmldeveloper@xxxxxxxxx>]

Reading the uboot source code:

In common/cmd_bootm.c:

int do_bootm (cmd_tbl_t *cmdtp, int flag, int argc, char *argv[])

{

And within this do_bootm_linux() is called:

            do_bootm_linux  (cmdtp, flag, argc, argv,

                             addr, len_ptr, verify);

And inside do_bootm_linux() (platform-specific, for x86 it is lib_i386/i386_linux.c) is the load_zimage() function being called, which is effectively loading the kernel image file.
