flash: complete CONFIG_SYS_NO_FLASH move with renaming

2017-02-12T19:30:25+00:00

We repeated partial moves for CONFIG_SYS_NO_FLASH, but this is
not completed. Finish this work by the tool.

During this move, let's rename it to CONFIG_MTD_NOR_FLASH.
Actually, we have more instances of "#ifndef CONFIG_SYS_NO_FLASH"
than those of "#ifdef CONFIG_SYS_NO_FLASH".  Flipping the logic will
make the code more readable.  Besides, negative meaning symbols do
not fit in obj-$(CONFIG_...) style Makefiles.

This commit was created as follows:

[1] Edit "default n" to "default y" in the config entry in
    common/Kconfig.

[2] Run "tools/moveconfig.py -y -r HEAD SYS_NO_FLASH"

[3] Rename the instances in defconfigs by the following:
  find . -path './configs/*_defconfig' | xargs sed -i \
  -e '/CONFIG_SYS_NO_FLASH=y/d' \
  -e 's/# CONFIG_SYS_NO_FLASH is not set/CONFIG_MTD_NOR_FLASH=y/'

[4] Change the conditionals by the following:
  find . -name '*.[ch]' | xargs sed -i \
  -e 's/ifndef CONFIG_SYS_NO_FLASH/ifdef CONFIG_MTD_NOR_FLASH/' \
  -e 's/ifdef CONFIG_SYS_NO_FLASH/ifndef CONFIG_MTD_NOR_FLASH/' \
  -e 's/!defined(CONFIG_SYS_NO_FLASH)/defined(CONFIG_MTD_NOR_FLASH)/' \
  -e 's/defined(CONFIG_SYS_NO_FLASH)/!defined(CONFIG_MTD_NOR_FLASH)/'

[5] Modify the following manually
  - Rename the rest of instances
  - Remove the description from README
  - Create the new Kconfig entry in drivers/mtd/Kconfig
  - Remove the old Kconfig entry from common/Kconfig
  - Remove the garbage comments from include/configs/*.h

cmd: move CONFIG_CMD_UNZIP and CONFIG_CMD_ZIP to Kconfig

2017-02-08T21:24:28+00:00

CONFIG_CMD_ZIP is not defined by any board.  I am moving
CONFIG_CMD_UNZIP to defconfig files except UniPhier SoC family.

I am the maintainer of UniPhier platform, so I know "select CMD_UNZIP"
is better for this platform.

cmd: bootm: fix build when CONFIG_CMD_IMLS_NAND

2017-02-08T20:56:32+00:00

Now when CONFIG_CMD_IMLS_NAND is enabled the u-boot build will fail,
because nand_read_skip_bad() function has been changed to accept more
parameters, hence fix it.

cmd: rework "license" command

2017-02-08T20:56:28+00:00

The previous commit ("add a new command to show .config contents")
improves the basic infrastructure of "embed a compressed file into
the U-Boot image, and print it by a command".  The same pattern for
the "license" command.

This commit reworks the command to improve the following:

[1] Improve log style

Kbuild style log

  GZIP    cmd/license_data.gz
  CHK     cmd/license_data_gz.h
  UPD     cmd/license_data_gz.h
  CHK     cmd/license_data_size.h
  UPD     cmd/license_data_size.h

instead of the bare Make log:

cat ./Licenses/gpl-2.0.txt | gzip -9 -c | \
		tools/bin2header license_gzip > ./include/license.h

[2] Collect related code into the "cmd" directory

Prior to this commit, the license.h was created by tools/Makefile,
placed under the "include" directory, included from cmd/license.c,
and deleted by the top-level Makefile.  It is not a good idea to
scatter related code.

[3] Drop the fixed-malloc size LICENSE_MAX

Just allocate the minimum required size of buffer because we know
the size of the original gpl-2.0.txt.

[4] Fix more issues

Terminate the buffer with zero to prevent puts() from over-running.
Add "static" to do_license.

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.

booti: Set images.os.arch

2017-01-28T19:04:51+00:00

Commit ec6617c39741adc6c549 ("armv8: Support loading 32-bit OS in AArch32
execution state") broke SMP boot by assuming that an image is 32-bit if
the arch field in the spin table != IH_ARCH_DEFAULT (i.e.
IH_ARCH_ARM64), even if the arch field also does not match IH_ARCH_ARM,
even though nothing actually set the arch field in the spin table.

Commit e2c18e40b111470f ("armv8: fsl-layerscape: SMP support for loading
32-bit OS") fixed this for bootm by setting the arch field of the spin
table based on images.os.arch, but booti remaineed broken because it did
not set images.os.arch.

cmd, disk: convert CONFIG_PARTITION_UUIDS, CMD_PART and CMD_GPT

2017-01-28T13:48:03+00:00

We convert CONFIG_PARTITION_UUIDS to Kconfig first.  But in order to cleanly
update all of the config files we must also update CMD_PART and CMD_GPT to also
be in Kconfig in order to avoid complex logic elsewhere to update all of the
config files.
