From 6acc7d485c24c00e111c61b2e6dff9180faebcae Mon Sep 17 00:00:00 2001 From: Dmitri Vorobiev Date: Sat, 21 Nov 2009 22:34:41 +0200 Subject: 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 Cc: linux-mips@linux-mips.org Patchwork: http://patchwork.linux-mips.org/patch/689/ Signed-off-by: Ralf Baechle --- arch/mips/configs/sb1250-swarm_defconfig | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'arch/mips/configs/sb1250-swarm_defconfig') diff --git a/arch/mips/configs/sb1250-swarm_defconfig b/arch/mips/configs/sb1250-swarm_defconfig index 5244716b67f..7f07bf02b83 100644 --- a/arch/mips/configs/sb1250-swarm_defconfig +++ b/arch/mips/configs/sb1250-swarm_defconfig @@ -960,7 +960,7 @@ CONFIG_ENABLE_MUST_CHECK=y # CONFIG_HEADERS_CHECK is not set # CONFIG_DEBUG_KERNEL is not set # CONFIG_SAMPLES is not set -CONFIG_CMDLINE="" +# CONFIG_CMDLINE_BOOL is not set # CONFIG_SB1XXX_CORELIS is not set # -- cgit v1.2.3-70-g09d2
