I am Linux software engineer. These days I was debugging a MPC8313 system.
In the debugging process, some source code in the kernel makes me puzzled. So
I have find your email address in the source code. I think you can give me
some advises to solve the problem.
My version is linux-2.6.23.9 and I use the device tree(dtb) to
booting the kernel. In my bootloader I use the following code to jump to the
kernel.
(*image)((bd_t *)dtb_entry, (unsigned int)image, 0, 0, 0);
The dtb_entry is the address of dtb file which in the SDRAM, the image is the
kernel entry point. I flashed some LEDs in my board. So I can make sure the
program run to the machine_init() which is defined in the
/arch/powerpc/kernel/setup_32.c
In order to trace the problem I search the source code. I can find that these
information is printed by the start function which is defined in the
/arch/powerpc/boot/main.c.
Fourth more I have found that the kernel call the platform_init which is
defined in the /arch/powerpc/boot/cuboot-83xx.c. looking the file head I have
known you are the author for this file.
Could you told me how the kernel call the platform_init function and I hope
you can show me the booting process of the MPC83xx linux or you could give me
some document about it.
