Summary: uImage doesn't pass parameter from uboot to kernel now

Details:

uImage doesn't pass parameter from uboot to kernel now from about May 20.

And so kernel command line is empty when kernel boots up,which make jffs testcase etc fails.

Follow-ups

--- Mike Frysinger 2009-05-26 00:16:19

are you sure you didnt compile the kernel command line in ?

--- Mingquan Pan 2009-05-26 00:37:41

The CONFIG_CMDLINE_BOOL is not set by default. And I also didnit change that.

Attached the config for jffs2 test case.

--- Mingquan Pan 2009-05-27 02:15:01

It can pass now. So close.
