Somebody in the thread at some point said:
| - The newer GTA02 is in the S3C2440 submenu, but selects CPU_S3C2442.
| - If I save the options CONFIG_S3C2410_CLOCK is _not_ defined!
| - If I select the "old" GTA02 and thus CPU_S3C2440,
| CONFIG_S3C2410_CLOCK _is_ defined!
| Furthermore the GTA02 files reside in mach-s3c2410 and mach-s3c2440
| but not in mach-s3c2442. So my question is WTF is wrong here?
There's commonality in the s3c24xx (and even up to the 64xx stuff in
some cases) so stuff in inherited from the earliest chips normally in
this platform code.
I think the problem you spotted is that selecting 2442 should select
necessary 2410 stuff, it's a genuine dependency.
As for mach-gta02.c bring in the 2440 directory, it's an accident of
history I believe. At this point I think it's safe to say GTA02 is
definitely settled on s3c2442 :-) so if you are patching in this area
and fancy moving it to 2442, feel free.
