[PATCH] arc: Removed local initramfs source file from axs101 configuration.

[Carlos Palminha]

Hi guys,

I don't think maintaining that flag this in the kernel is correct... the kernel simply doesn't compile out of the box.
If you grep for  CONFIG_INITRAMFS_SOURCE, ARC is the only architecture that uses that kernel flag by default pointing to an external directory.
I don't think this is proper to have it like this by default from the kernel point of view.

Regards,
C.Palminha
