-Subject: MIPS: Get kernel parameters from kexec-tools
-
-Before, we simply use the command lines from the original bootloader,
-but it is not convenient. Now, we accept the kernel parameters from the
---command-line or --append option of the kexec-tools. But If not
---command-line or --apend option indicated, will fall back to use the
-ones from the original bootloader.
