arch/powerpc/boot/.gitignore questions

[Randy Dunlap]

Hi,

I was looking at the arch/powerpc/boot/.gitignore file.
Why are all of those non-local-directory files listed there?
E.g., empty.c, inf*.c, inf*.h, zconf.h, zlib.h, zutil.h, etc.

And what is "dtc"?  I see a dtc-src directory, but "dtc" is MIA.
Same for kernel-vmlinux.strip.*

Thanks,
~Randy

./arch/powerpc/boot/dtc

I believe if the dts is built into u-boot, the dtc is not built.

I don't see a vmlinux.strip.* rule. I ignore vmlinux.strip.

This is never the case. The device tree is considered to be  part  of
and provided to the boot loader by the kernel.

No, it's provided to the kernel by the firmware.  That the repository 
for the files that the user provides to u-boot for this purpose happens 
to live in the Linux source tree is irrelevant.

Why would these files be listed in arch/powerpc/boot/.gitignore ??

Where do you see that?  That's not in 2.6.27-rc6 nor in the current
powerpc.git tree.  They both have:

> pwd
/var/linsrc/lin2627-rc6/arch/powerpc/boot
> ls -ld dt*
drwxr-xr-x 2 rdunlap users 4096 Jul 13 14:51 dtc-src/
drwxr-xr-x 2 rdunlap users 4096 Sep  9 19:33 dts/


which leads me to believe that the .gitignore entry should be either
dts or dtc-src or both, but not "dtc".

again, where are you looking?
This is in the current arch/powerpc/boot/.gitignore file.

Because they're created when building a bootwrapper?

Of course not -- it wouldn't be in gitignore if it weren't a generated file.

Why would we want to ignore source directories?  dtc is the binary that 
is built from dtc-src.

Thanks.  Got it.
