Help loading kernel image

[Tamamontu M]

Hi Guys,

I have a EP9307 (Arm 920T) based board. The design is based on Cirrus logic 
EP9307 development board.  At present the boot sequence is first stage 
bootloader (com port) => redboot (com port) => Zimage (ethernet) => Ramdisk 
(ethernet).

I want to load Zimage directly from SDcard without using redboot. I have 
modified first stage bootloader to boot from spi eeprom. This in turn loads a 
second stage bootloader which initializes Sdcard. At present I have not 
implemented a file system in second stage bootloader.  I will have to stick to 
FAT file system as the users would be copying binaries from windows machine so 
that they can upgrade the firmware. 


I have been reading about arm kernel boot process on following links. 

http://www.simtec.co.uk/products/SWLINUX/files/booting_article.html 

http://www.webworldarticles.com/e/a/title/Loading-the-kernel-into-memory-and-starting-a-Linux-system/



One of the kernel boot requirments is boot parameters Atag List. At present 
redboot sets these parameters. Is there any way to see what these parameters 
are. How to create this list.

Has any one done anything similar. Can some one please share there inputs/ 
provide some pointers on this. 


Thanks
Tama
