MIPS: Fix and enhance built-in kernel command line
Currently, MIPS kernels silently overwrite kernel command-line parameters hardcoded in CONFIG_CMDLINE by the ones received from firmware. Therefore, using firmware remains the only reliable method to transfer the command-line parameters, which is not always desirable or convenient, and the CONFIG_CMDLINE option is thereby effectively rendered useless. This patch fixes the problem described above and introduces a more flexible scheme of handling the kernel command line, in a manner identical to what is currently used for x86. The default behavior, i.e. when CONFIG_CMDLINE_BOOL is not defined, retains the existing semantics, and firmware command-line arguments override the hardcoded ones. [Ralf: I fixed up all the defconfig files so the stay unaffected by this change.] Signed-off-by: Dmitri Vorobiev <dmitri.vorobiev@movial.com> Cc: linux-mips@linux-mips.org Patchwork: http://patchwork.linux-mips.org/patch/689/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
