dtc updates for 4.17

maintainercover dtc updates for 4.17
This series updates building dtc with flex and bison rather than using the _shipped files and updates dtc to the current upstream version. The new dtc adds some new warnings, so turn off the noisiest ones. While here adjusting the warnings, we can also now re-enable some that have gotten fixed.
Yamada-san, I figured out why you wanted the dtc update after I wrote the patch to remove the shipped files... :) I guess you may already have a similar patch. I suppose the first patch should go into 4.16, but nothing needs the fix yet. So it may be easier if you can just ack it and I'll keep it with the rest of the series.

Commit eea199b445f6 ("kbuild: remove unnecessary LEX_PREFIX and YACC_PREFIX") removed YACC_PREFIX definition, but left one use of it. There was not any build error since there is no user of "cmd_bison_h" currently. Remove the last remaining occurrence of YACC_PREFIX.

Hmm, I am not 100% sure about this.
Is there a case where resulted DTBs depend on DTC version?
If I understand correctly,
DTS and DTB are 1:1
Unlike CC, there is no room for optimization.
Some possibilities could be:
- specification is updated.
( /dts-v1/ in DTS should be updated if so)
- buggy DTC version generates broken DTBs.

Maybe I was wrong.
Is there room for optimization
in 'DT strings' section?
I guess it is optimized enough to avoid string duplication, but there could be different results
without changing the specification.

What I care about is rebuilding so new warnings get emitted especially when developing those checks. Right now I have to manually delete the dtb files each time.

Fair enough.
Probably, it is better to make sure all DTB are compiled by the latest DTC.
Please go ahead.

As you know, this introducesscripts/dtc/dtc-parser.y: warning: 3 shift/reduce conflicts [-Wconflicts-sr] then, the next commit will fix it.
I do not have a strong opinion about the parch order. It would be ridiculous to update *_shipped
that will be immediately removed. So, probably this is OK.
FWIW.
This is completely out of realm of my field since
I speak Japanese in my daily life.
Is it better to change
the 'singular vs plural' in the comment block?
# This script assumes that the dtc and the linux git trees are in the
# same directory. After building dtc in the dtc directory, it copies the # source files and generated source files into the scripts/dtc directory # in the kernel and creates a git commit updating them to the new # version.
After this commit, 'version_gen.h' will be the only generated file. "generated source files" sounds like we have more.
Please take it FWIW.
I am just nit-picking
according to what I learned at junior high school, which might be wrong.
Otherwise,

You are right as we do have that hidden generated file. I worry changing it could become stale too if we add more generated files sometime in the future. I've changed it to "generated source file(s)" to cover both cases. Not sure that's really proper English grammar, but it is widely used.

Commit c8b38f65fdec upstream ("libfdt: Remove leading underscores from identifiers") changed the multiple inclusion define protection, so the kernel's libfdt_env.h needs the corresponding update.

maintainerPATCH 6/6 scripts: turn off some new dtc warnings by default
In reply to Rob HerringThe latest dtc update adds some new noisy warnings, so turn them off by default. Disable 'avoid_unnecessary_addr_size' and 'alias_paths'. They can be re-enabled by building with 'W=1'.

Quoted 9 lines
This series updates building dtc with flex and bison rather than using the
_shippedfiles and updates dtc to the current upstream version. The new dtc adds some new warnings, so turn off the noisiest ones. While here adjusting the warnings, we can also now re-enable some that have gotten fixed.Yamada-san, I figured out why you wanted the dtc update after I wrote the patch to remove the shipped files... :) I guess you may already have a similar patch.
Exactly, this is what I expected.
What I blocked me was ambiguous grammar
as I mentioned in:
https://www.spinics.net/lists/kernel/msg2670836.html
Quoted 3 lines
I suppose the first patch should go into 4.16, but
nothing needs the fix yet. So it may be easier if you can just ack it and I'll keep it with the rest of the series.
Just browsing the series, nothing of the rest of it depends on 1/6 but feel free to pick it to your tree if you want.
