| * common: DDR2 SPD checksum.Renaud Barbier2013-06-271-0/+1
| | | | | | | | | | | | | | | | | | | | | | The code calculates the DDR2 SPD checksum as per JEDEC standard No 21-C Appendix X (revision 1.2) The code is based on the equivalent files from U-Boot version git-a71d45d.

| |/ | | | | | | | | | | | | | | | | | | | | | | Add mem_test routine. Useful to detect timing problems if someone porting a new device to barebox. This test includes a data bus test, address bus test and integrity check of memory. This mem_test routine has as parameter start and end address of testing space. The last parameter can skip the integrity check. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* Add in-system barebox update infrastructureSascha Hauer2012-10-171-0/+1
| | | | | | | | | | | | | | | Currently in-system update means to write an arbitrary file to an arbitrary device. There is no sanity check if the flashed image is of the right type or will fit onto the device. Furthermore some SoCs need a special preparation step for their images before flashing them. This adds a barebox in-system update infrastructure. Boards can register update handlers which know how to make the board bootable. The available handlers can be listed to be able to select one, different force levels give the user the chance to know it better. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* defaultenv: dependencies fixesSascha Hauer2012-10-121-9/+12
| | | | | | | | | | | | | | When a build with a compressed default environment is done and then environment compression is disabled, barebox_default_env.h is not regenerated because its dependency (now barebox_default_env) is still up to date. This results in a corrupt default environment. This patch fixes this by adding a cmd_env_h and changing barebox_default_env.h to FORCE. As a side effect barebox_default_env.h is no longer generated in include/generated/ but in common/ as we have to add barebox_default_env.h to $(targets) (extra-y).

| * environment generation: Fix dependenciesSascha Hauer2012-09-281-8/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The dependencies for generating the environment do not work properly: - If files are removed from the defaultenv, a subsequent make will not update the default environment. - If CONFIG_DEFAULT_ENVIRONMENT_PATH changes, the default environment also will not be regenerated. This patch fixes this by introducing a cmd_env which has the content of $(ENV_FILES) in the command so that the if_changed mechanism recognizes a change when $(ENV_FILE) changes. This also results in a nice " ENV " string in the build process. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * Enable a way to provide the reason for "being here"Juergen Beisert2012-07-181-0/+1
| | | | | | | | | | | | | | | | | | | | Many architectures support a way to detect why the bootloader is running. This patch adds a global variable to be able to use the cause in some kind of shell code to do special things on demand. For example to do an emergency boot, when the last boot fails and the watchdog reactivate the hanging system.

* Add next generation default environment templateSascha Hauer2012-05-181-0/+7
| | | | | | | | | | | | | | | | | | | | This adds a new environment template which aims to be more flexible and configurable. Instead of having mainly two scripts (a config script and a boot script) this template uses initscripts which control the startup behaviour and configuration. Also we have boot scripts in /env/boot which configure a single boot configuration. Additional boot entries can be added by board specific entries or during runtime by copying and editing a template entry. Some more helpers handle for example network interfaces which can now be brought up with 'ifup'. We use the automount feature to configure mountpoints together with the commands to bring up the devices behind these mountpoints. Optionally menu support is available which hides many details behind a nice looking interface. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* booting: more flexible Linux bootargs generationSascha Hauer2012-05-141-0/+1
| | | | | | | | | | | | | | | | | | | | | | We currently use the environment variable 'bootargs' to get the Linux bootargs. This patch allows for a more flexible bootargs generation using global variables. With it the Linux bootargs are concatenated from multiple variables. This allows to replace parts of the bootargs string without having to reconstruct it completely. With this bootargs can be constructed like: global linux.bootargs.base="console=ttyS0,115200" global linux.bootargs.ip="ip=dhcp" global linux.mtdparts="physmap-flash.0:512K(nor0.barebox),-(root)" This will then automatically be combined into a kernel bootargs string during boot. If the 'linux.bootargs.' variables are all empty the old standard 'bootargs' way will be used. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* add 'global' commandSascha Hauer2012-05-141-0/+1
| | | | | | | | | | | This implements global shell variable support. This is done by registering a new device named 'global', so global variables are just plain device parameters. Global variables are useful for storing the global state in the environment. Currently we do this by sourcing scripts instead of executing them which is quite limiting.

You can register multiple hook for the same filetype. They will be execute in the invert order of register. If a hook does not handle the file you just return -ERESTARTNOHAND; This is only available with hush parser. Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>
* Makefile: fix build timestampsSascha Hauer2012-04-151-0/+17
| | | | | | | | | | | This patch adds the scripts/mkcompile_h from the Kernel. This gives us additional information about the build like who built this binary and with which compiler. Currently the only information used is the build timestamp and the generation number. This also fixes the build timestamp in the banner which is now correct even with consecutive builds without making clean in between. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* Add generic poll infrastructureMarc Kleine-Budde2010-12-201-0/+1
| | | | | | | | | | | | | | | | | | | | | Barebox does not have interrupt functionality. Nevertheless it's sometimes useful to periodically call functions, like for example a heartbeat LED or watchdog reset. Instead of cluttering the code with calls to these functions this patch adds a generic polling infrastructure. Code which might run for longer now can call poller_call() periodically which in turn will call all registered pollers. This patch adds a call to poller_call in two generic pathes. First of them is getc() which covers waiting for uart input. Second is ctrlc() which should be called anyway from code which might run for longer. So instead adding poller_call directly to your code, consider checking ctrlc instead which also gives additional convenience to the user. The poller code is safe against reentrancy which means that it's safe to call poller_call inside a poller.
