| * 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.

* | uimage: introduce UIMAGE Kconfig symbolSascha Hauer2012-07-251-2/+2
|/ | | | | | | Both the uimage command and the bootm command need uImage support, so add a Kconfig symbol for it to be able to select it properly. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* 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.

* Introduce binfmt supportJean-Christophe PLAGNIOL-VILLARD2012-04-181-0/+1
| | | | | | | | | | | | | This will allow to execute any file and detect it's type to handle it. This will allow to use shell for bootp bootfile or dfu. 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>

* reimplement uImage codeSascha Hauer2011-12-151-0/+1
| | | | | | | | | | | | | Provide a new API for accessing uImages which makes it easy for commands to open images, verify them, load to (free) sdram regions and show information about uImages. - We now do not load the image to malloced space anymore. - The data in the header is now stored in cpu native endianess after uimage_open which makes it easy to access the header data. - uImage can be loaded to dynamically allocated sdram regions.

* add file detection supportSascha Hauer2011-11-291-0/+1
| | | | | | | | | | | | | | | Several filetypes can be autodetected. Barebox could make use of this in several ways: - Add a command to detect filetypes - detect arm zImages and uImages to unify the different boot commands - maybe detect UBI or JFFS2 images to construct parts of the kernel command line - select correct uncompression function based on filetype This patch adds basic support to detect filetypes.

* add dummy_malloc functionsSascha Hauer2011-04-111-1/+2
| | | | | | | | | | For some environments the dummy malloc functions offer a very small alternative implementation. malloc will get its memory from sbrk() and never frees memory again.

* 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.
