Re: [U-Boot-Users] kernel parameters for ARM

Hi,

I currently have the problem that on my PXA250 based board the kernel command line parameters from the u-boot environment variable "bootargs" are not actually transferred to the kernel.

When looking at the code in lib_arm/armlinux.c:do_bootm_linux() I'm wondering how the code is intended to work: the setup_commandline_tag() function puts some stuff in the 'params' structure, but I cannot see that this information is passed on to the kernel. The kernel call does only transfer the architecture number, and the only other thing which could do the job is cleanup_before_linux() (which doesn't do it).

take a look a "parse_tags()" in "arch/arm/kernel/setup.c".
