2017-02-12T19:31:25+00:00

Re-sync all files under the scripts/kconfig directory with
Linux 4.10.

Some parts include U-Boot own modification.  I made sure to not
revert the following commits:

 5b8031ccb4ed ("Add more SPDX-License-Identifier tags")
 192bc6948b02 ("Fix GCC format-security errors and convert sprintfs.")
 da58dec86616 ("Various Makefiles: Add SPDX-License-Identifier tags")
 20c20826efab ("Kconfig: Enable usage of escape char '\' in string values")

api: Convert to Kconfig

Now that we have a Kconfig for the API, convert the two boards that
are using this to Kconfig and remove CONFIG_API from the whitelist.

cmd: add a new command "config" to show .config contents

2017-02-08T20:56:26+00:00

This feature is inspired by /proc/config.gz of Linux.  In Linux,
if CONFIG_IKCONFIG is enabled, the ".config" file contents are
embedded in the kernel image.  If CONFIG_IKCONFIG_PROC is also
enabled, the ".config" contents are exposed to /proc/config.gz.
Users can do "zcat /proc/config.gz" to check which config options
are enabled on the running kernel image.

The idea is almost the same here; if CONFIG_CMD_CONFIG is enabled,
the ".config" contents are compressed and saved in the U-Boot image,
then printed by the new command "config".

The usage is quite simple.  Enable CONFIG_CMD_CONFIG, then run
 > config
from the command line interface.  The ".config" contents will be
printed on the console.

This feature increases the U-Boot image size by about 4KB (this is
mostly due to the gzip-compressed .config file).  By default, it is
enabled only for Sandbox because we do not care about the memory
footprint on it.  Of course, this feature is architecture agnostic,
so you can enable it on any board if the image size increase is
acceptable for you.

scripts: import bin2c.c from Linux 4.10-rc6

2017-02-08T20:56:19+00:00

Import scripts/basic/bin2c.c of Linux.

In Linux Kernel, this file was moved to scripts/basic directory by
commit 8370edea81e3 ("bin2c: move bin2c in scripts/basic").

In U-Boot, we do not need to follow that commit.  Just put it in the
original directory "scripts".

x86: Add SPL build rules for start-up code

2017-02-06T03:38:46+00:00

When SPL is used we need to build the 16-bit start-up code. Add Makefile
rules to handle this.

mmc: move CONFIG_GENERIC_MMC to Kconfig

2017-01-31T12:50:47+00:00

Now, CONFIG_GENERIC_MMC seems equivalent to CONFIG_MMC.

Let's create an entry for "config GENERIC_MMC" with "default MMC",
then convert all macro defines in headers to Kconfig.  Almost all
of the defines will go away.

I see only two exceptions:
  configs/blanche_defconfig
  configs/sandbox_noblk_defconfig

They define CONFIG_GENERIC_MMC, but not CONFIG_MMC.  Something
might be wrong with these two boards, so should be checked later.

Anyway, this is the output of the moveconfig tool.

This commit was created as follows:

[1] create a config entry in drivers/mmc/Kconfig

[2] tools/moveconfig.py -r HEAD GENERIC_MMC

[3] manual clean-up of garbage comments in doc/README.* and
    include/configs/*.h
