PATCH 1/1 Revert "build: Use filechk rules to create and update u-boot.lds"

This reverts commit a8b993eb81c142a439c24b871a2317f765fe5397.

Commit a8b993eb claims it fixes u-boot.lds rule by replacing $(call if_changed) with $(call filechk).

But the problem had already been fixed by commit 395e60cd a few days before commit a8b993eb was posted.

There is no reason to apply commit a8b993eb. What is worse is $(call filechk) is too strong to fix the problem and looks weird.

Date of the two patches:

[1] commit 395e60cdc292dc0183c6867d34b43f14a373df55
Author: Masahiro Yamada <[email protected]>
AuthorDate: Wed Apr 9 20:10:43 2014 +0900
Commit: Tom Rini <[email protected]>
CommitDate: Fri Apr 11 10:08:42 2014 -0400
replaces $(call if_changed) -> $(call if_changed_dep)

[2] commit a8b993eb81c142a439c24b871a2317f765fe5397
Author: Jon Loeliger <[email protected]>
AuthorDate: Tue Apr 15 16:09:37 2014 -0500
Commit: Tom Rini <[email protected]>
CommitDate: Fri Apr 18 16:14:16 2014 -0400
replaces $(call if_changed) -> $(call filechk)

A conflict must have happened when applying [2], but somehow it was applied, sadly.

Bummer. Sorry about that. I didn't see Masahiro's patch.

What is worse is
$(call filechk) is too strong to fix the problem and looks weird.

I'm sure I don't understand that critique at all. "Looks weird"?

However, your patch (395e60cdc) is better in that it catches both the regular top-level and the SPL build's load scripts. Mine did not.

Hi Jon,

The linker script is processed by C-preprocessor. It means the dependency of included files should be tracked to decide if the linker script should be updated or not. This is the same as the rule of generationg objects. ( *.c -> *.o or *.S -> *.o)

$(call filechk ) does not do this dependency tracking and always runs the preprocessor.

The why it looks weird to me.

Best Regards
