buildman: adjust for Kconfig

2014-07-30T18:42:02+00:00

Use "make _defconfig" instead of "make _config".

Invoke tools/genboardscfg.py to generate boards.cfg when it is missing.

tools: add genboardscfg.py

2014-07-30T18:42:02+00:00

Now the primary data for each board is in Kconfig, defconfig and
MAINTAINERS.

It is true boards.cfg is needed for MAKEALL and buildman and might be
useful to brouse all the supported boards in a single database.
But it would be painful to maintain the boards.cfg in sync.

So, this is the solution.
Add a tool to generate the equivalent boards.cfg file based on
the latest Kconfig, defconfig and MAINTAINERS.

We can keep all the functions of MAKEALL and buildman with it.

The best thing would be to change MAKEALL and buildman for not
depending on boards.cfg in the future, but it would take some time.

kconfig: switch to Kconfig

2014-07-30T12:48:03+00:00

This commit enables Kconfig.
Going forward, we use Kconfig for the board configuration.
mkconfig will never be used. Nor will include/config.mk be generated.

Kconfig must be adjusted for U-Boot because our situation is
a little more complicated than Linux Kernel.
We have to generate multiple boot images (Normal, SPL, TPL)
from one source tree.
Each image needs its own configuration input.

Usage:

Run "make _defconfig" to do the board configuration.

It will create the .config file and additionally spl/.config, tpl/.config
if SPL, TPL is enabled, respectively.

You can use "make config", "make menuconfig" etc. to create
a new .config or modify the existing one.

Use "make spl/config", "make spl/menuconfig" etc. for spl/.config
and do likewise for tpl/.config file.

The generic syntax of configuration targets for SPL, TPL is:

  /

Here,  is either 'spl' or 'tpl'
       is 'config', 'menuconfig', 'xconfig', etc.

When the configuration is done, run "make".
(Or "make _defconfig all" will do the configuration and build
in one time.)

For futher information of how Kconfig works in U-Boot,
please read the comment block of scripts/multiconfig.py.

By the way, there is another item worth remarking here:
coexistence of Kconfig and board herder files.

Prior to Kconfig, we used C headers to define a set of configs.

We expect a very long term to migrate from C headers to Kconfig.
Two different infractructure must coexist in the interim.

In our former configuration scheme, include/autoconf.mk was generated
for use in makefiles.
It is still generated under include/, spl/include/, tpl/include/ directory
for the Normal, SPL, TPL image, respectively.

buildman: make sure to invoke GNU Make

2014-07-29T15:48:40+00:00

Since the command name 'make' may not be GNU Make on some platforms
such as FreeBSD, buildman should call scripts/show-gnu-make to get
the command name for GNU MAKE (and error out if it is not found).

patman: make "No recipient" checking more tolerant

2014-07-28T03:57:24+00:00

If Series-to tag is missing, Patman exits with a message
"No recipient".

This is just annoying for those who had already added
sendemail.to configuration.

I guess many developers have

  [sendemail]
          to = u-boot@lists.denx.de

in their .git/config because the 'To: u-boot@lists.denx.de' field
should always be added when sending patches.

That seems more reasonable rather than adding
'Series-to: u-boot@lists.denx.de' to every patch series.

Patman should exit only when both Series-to tag and sendemail.to
configuration are mising.

buildman: Support in-tree builds

2014-07-28T03:52:55+00:00

At present buildman always builds out-of-tree, that is it uses a separate
output directory from the source directory. Normally this is what you want,
but it is important that in-tree builds work also. Some Makefile changes may
break this.

Add a -i option to tell buildman to use in-tree builds, so that it is easy
to test this feature.

buildman: Add -C option to force a reconfigure for each commit

2014-07-28T03:52:48+00:00

Normally buildman wil try to configure U-Boot for a particular board on the
first commit that it builds in a series. Subsequent commits are built
without reconfiguring which normally works. Where it doesn't, buildman
automatically reconfigures and retries.

To fully emulate the way MAKEALL works, we should have an option to disable
this optimisation.

Add a -C option to cause buildman to always reconfigure on each commit.

buildman: Avoid retrying a build if it definitely failed

2014-07-23T15:52:36+00:00

After a build fails buildman will reconfigure and try again, if it did not
reconfigure before the build. However it doesn't actually keep track of
whether it did reconfigure on the previous attempt.

Fix that logic to avoid a pointless rebuild. This speeds things up quite a
bit for failing builds. Previously they would always be built twice.
