tools: env: include compiler.h

2015-12-14T01:22:00+00:00

With gcc 5.2 and later we get a bunch of "error: unknown type name" for
'uint8_t', 'uint32_t' and friends.

Allow fw env tools to be available as library

2015-11-18T13:47:03+00:00

Sometimes it can be useful to link the fw_ tools instead
of having the fw_setenv/fw_printenv installed.
Patch exports the tool as library and allowes to link it
with own programs.

tools/env: allow config filename to be passed via command line argument

2015-11-18T13:47:02+00:00

When for example generating/manipulating SD card/eMMC images which
contain U-Boot and its environment(s), it is handy to use a given
configuration file instead of the compiled-in default one.
And since the default configuration file is expected under /etc
it's hard for an usual linux user account without special permissions
to use fw_printenv/fw_setenv for this purpose.
So allow to pass an optional filename via a new '-c' command
line argument.

Example:

$ ln -s fw_printenv tools/env/fw_setenv
$ cat fw_env.config
test.img 0x20000 0x20000
test.img 0x40000 0x20000

$ tools/env/fw_printenv -c ./fw_env.config fdt_file
fdt_file=imx28-duckbill.dtb

$ tools/env/fw_setenv -c ./fw_env.config fdt_file imx28-duckbill-spi.dtb

$ tools/env/fw_printenv -c ./fw_env.config fdt_file
fdt_file=imx28-duckbill-spi.dtb

tools/env/fw_env.h: Correct include order

2015-06-18T20:11:42+00:00

When building tools-only (or env) we need to be sure that we do use
 and do not use .  This will fix
problems such as running 'make defconfig' or 'make sandbox_config' and
then 'make tools-only'.

Based on the responses below to the thread add linux/kconfig.h higher in
the includes and drop the now unneeded autoconf.h lower down to ensure
the default environment is included correctly

Fix musl build

2015-05-08T21:24:17+00:00

This patch fixes cross-compiling U-Boot tools with the musl C library:
  * including  is needed for ulong
  * defining _GNU_SOURCE is needed for loff_t

Tested for target at91sam9261ek_dataflash_cs3.

fw_env.h: include autoconf.h

2015-05-05T23:52:07+00:00

Without this, when CONFIG_ENV_VARS_UBOOT_CONFIG is active we get
a compile time error when doing 'make env'.
In file included from tools/env/fw_env.c:117:0:
include/env_default.h:110:11: error: expected ‘}’ before ‘CONFIG_SYS_ARCH’

When building U-Boot this is included indirectly by the compiler switch

add example for file on VFAT filesystem usage

2015-02-17T11:27:44+00:00

For example on a raspberry pi the u-boot environment can be
saved in a file on the first VFAT partition.
This example illustrates how to use it with fw_printenv/fw_setenv.

tools/env: Fix environment size and CRC on 64-bit hosts

2014-11-07T21:27:07+00:00

On architectures where 'long' is 64 bit, the u-boot environment
as seen by the fw_env tools was missing 4 bytes.
This patch fixes getenvsize(), and thus also ensures that the
environment's CRC32 checksum is calculated correctly.

tools/env: change stripping strategy to allow no-stripping

2014-09-24T22:30:27+00:00

When building the U-Boot tools for non-ELF platforms (such as Blackfin
FLAT), since commit 79fc0c5f498c3982aa4740c273ab1a9255063d9c
("tools/env: cross-compile fw_printenv without setting HOSTCC"), the
build fails because it tries to strip a FLAT binary, which does not
make sense.

This commit solves this by changing the stripping logic in
tools/env/Makefile to be similar to the one in tools/Makefile. This
logic continues to apply strip to the final binary, but does not abort
the build if it fails, and does the stripping in place on the final
binary. This allows the logic to work fine if stripping doesn't work,
as it leaves the final binary untouched.

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.
