Currently, I do not see any such file as arch/x86/configs/xo_1.5_defconfig
Doing "ls -l arch/x86/configs gives me" ::
[ajay at localhost olpc-kernel]$ ls -l arch/x86/configs/
-rw-rw-r--. 1 ajay ajay 7511 Jun 9 05:37 i386_defconfig
-rw-rw-r--. 1 ajay ajay 7528 Jun 9 05:37 x86_64_defconfig
Are there some additional steps to generate the config file for XO-1.5?
Secondly, is the "marvell" module generatable only on the XO-1.5? As far as
I know, the OmniVersion sensor works since the earliest series of laptops?
