[U-Boot] [PATCH] tools: make it possible to build tools unconfigured

Sometimes we want to build common tools without configuring for specific target. Currently top Makefile has some support for this but it doesn't work. This patch tries to fix this. Things changed: - config.mk disable 'ld script not found error' in case if we are building tools only. - Makefile mkimage relies on autogenerated version so we need to move $(VERSION_FILE) rule out of ifeq and make tools rule depend on it. - tools/Makefile put common/env_embedded.o and envcrc.o to object list conditionally. This fixes errors during dependency generation.

i think you'll need to split this up in logical sep changesets since you are fixing different problems.
Things changed:
- config.mk disable 'ld script not found error' in case if we are
building tools only.
i dont like copying & pasting the same logic in multiple places. this is how code rots and bug fixes diverge.
considering LDSCRIPT/CONFIG_SYS_LDSCRIPT only get used by the top level u-boot file, and only when the system is configured, i wonder if we shouldnt just rip it out of config.mk and into the top level Makefile.
let's see what Scott thinks ...
- Makefile mkimage relies on autogenerated version so we need to
move $(VERSION_FILE) rule out of ifeq and make tools rule depend on it.
the VERSION_FILE changes look fine
- tools/Makefile put common/env_embedded.o and envcrc.o to object list
conditionally. This fixes errors during dependency generation.
pretty sure this breaks board builds. if the only thing this fixes is a harmless warning when generating dependency files, then i say ignore it. after all, this is how it has always worked in the past and no one really cared. -mike

There have been no warnings when generating dependencies.
Changes that cause new warnings need to be fixed.

yes, there has. you probably dont run `make tools` (at least, in an unconfigured tree), so you've never noticed.

you'll have to define "new" here. the warning he refers to has been there for many many releases, and for pretty much as long as i can remember.
i dont mind fixing warnings, but i do mind breaking the building of boards to fix a harmless warning. -mike

Hi Mike,
thanks for your comments.

Agreed. How should I fix this?

I'm sorry but I can't see how this can break the builds. Could you please be more specific? I've tried to build some boards, it actually works...

Yep, they are harmless but they are not warnings but rather scary errors actually. ;) I think it's better to fix them.

i might be thinking of a different env_embedded situation. a different problem with your patch to tools/Makefile: you copied the same logic multiple times which means more bitrot.

Yes, that's a good point. Your patch looks good to me. Should I write a commit message and repost it or will you?

Not exactly. I've reposted my patch splitting it into three as Mike suggested, and all these patches are already applied.
The commits you mention deal with the related problems that were introduced later during the development.

No, you can just drop it. It's already applied long ago (well, its second version).
