* environment: make default env path configurableSascha Hauer2011-04-122-3/+6
| | | | | | | | Normally the default path to save the environment is /dev/env0. However, we can't map a file in a fat filesystem to /dev/env0. So if we want to store the environment in a file in fat we have to make it configurable. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* add dummy_malloc functionsSascha Hauer2011-04-113-1/+44
| | | | | | | | | | 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. This of course is not suitable for interactive environments and thus depends on CONFIG_SHELL_NONE Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* malloc: put common memory functions to seperate fileSascha Hauer2011-04-113-50/+72
| | | | | | | These functions are needed independently of the specific malloc implementation, so move them out. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* add noshell supportSascha Hauer2011-04-111-1/+12
| | | | | | | | Some scenarios like initial bootloaders do not need interactive shell support, so make this optional. Without a shell a board must provide its own run_shell function. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* add block supportSascha Hauer2011-04-113-0/+270

* move version_string to seperate fileSascha Hauer2011-04-115-12/+18
| | | | | | | | | In a noninteractive environment barebox will be compiled without command support. So move version_string to a seperate file which is compiled unconditionally. Also, display the banner when the simple console support is used. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | With this kallsyms finally start working at least on ARM. This enables us resolving addresses into symbols which is particularly useful in combination with stack unwinding support. As kallsyms now compile and work we can remove the depends on BROKEN.

| * Add generic poll infrastructureMarc Kleine-Budde2010-12-204-0/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

|/ | | | | | | | | | commands/loadb.c doesn't build with CONFIG_CONSOLE_SIMPLE, because it uses fprintf / for_each_console (which uses console_list).

| | | | | | | | | | | | | | | | | | | | Positional parameters are not nice, so implement a getopt function. This has to be done as a builtin because otherwise we have no access to the parents argc/argv. getopt works as expected, here is a little example: while getopt "hs:" OPT do if [ $OPT = h ]; then echo "usage" exit 1 else echo "scr: opt: $OPT optarg: $OPTARG" fi done Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
