bloated defconfigs

[Andreas Kemnade]

Hi,

I just stumbled upon our defconfigs.

andi@aktux:~/gta04/gta04-kernel$ ls -l arch/arm/configs/ -Sr | tail -n
10 -rw-r--r-- 1 andi andi   9524 Apr  7 14:53 imote2_defconfig
-rw-r--r-- 1 andi andi   9985 Jul 28 13:34 imx_v6_v7_defconfig
-rw-r--r-- 1 andi andi  10118 Apr  7 14:53 ezx_defconfig

So we are bloated somehow. So I am wondering how these defconfigs are created.
AFAIK the tool is

make ARCH=arm CROSS_COMPILE=... savedefconfig

the file can then be used as a defconfig. I just did it and copied it over to
.config and used
make ARCH=arm CROSS_COMPILE=... olddefconfig

The result is the same. But the defconfig created by savedefconfig is only 20KB.
Well, what is the advantage? We have a better overview where we have
non-default values.

Regards,
Andreas
