* Shell: Handle aborting loops betterSascha Hauer2019-04-241-1/+3
| | | | | | | | | | | | | | | | | | It's easy to get stuck in an infinite loop in the hush shell: while true; do sleep 1; done The 'sleep' command will check for ctrl-c with the ctrlc() function. This will abort the sleep command. Hush then checks for ctrl-c again in the loop. The ctrl-c in the buffer has already been eaten by the sleep command, so the loop will continue. With this patch we remember the presence of a ctrl-c character in a variable instead of checking for a new character each time. The variable must be resetted explicitly by calling ctrlc_handled() which will be called by the shell in the outer loop. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* memory_display: move prototype to include/printk.hSascha Hauer2018-12-031-10/+0

* environment: Do not use environment when overlapping with other partitionsSascha Hauer2018-09-261-0/+10
| | | | | | | | | | | Environment partitions are usually specified with their hardcoded offset and size, either in the device tree or the board file. These partitions potentially overlap with other partitions read from the partition table. Overlapping partitions for sure have bad effects. Be more friendly to our users and warn them when such a situation occurs and stop using that partition for storing the environment. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* of: base: use root_node compatible as suggestion for a hostnameOleksij Rempel2018-01-171-0/+1
| | | | | | | | | | | | | | | | on some SoCs we can use generic PLL and RAM initialization. In this cases we create board file only to provide a host name. With this patch host name will be created from device tree compatible. For example: compatible = "board_vendor,board", "chip_vendor,soc" the host name will be: "board" This function will not overwrite a host name which is already set by board or machine code.

* ARM: Remove do_execute and thumb2_executeTrent Piepho2015-12-071-6/+0
| | | | | | | | | | | | | | | | | | | | In commit 104a6a7ccfb7928ca5dc28c8cbe0ea231ffc45ee support was added for Thumb2. It added do_execute() as a way to provide arch dependent calling veneers for use in "go" and thumb2_execute() as the thumb2 to arm veneer. But thumb2_execute() isn't necessary as gcc generates a proper calling sequence from a standard function pointer call. Thumb2 barebox is compiled with the AAPCS ABI which requires this. It also had a bug and didn't pass the arguments properly, but code execute via "go" rarely uses arguments so this wasn't very noticeable. Since thumb2 was always the only user of do_execute(), go ahead and delete that too. Signed-off-by: Trent Piepho <tpiepho@kymetacorp.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* restart: replace reset_cpu with registered restart handlersSascha Hauer2015-08-271-1/+0
| | | | | | | | | | | | | | | | | | | | | | This replaces the reset_cpu() function which every SoC or board must provide with registered handlers. This makes it possible to have multiple reset functions for boards which have multiple ways to reset the machine. Also boards which have no way at all to reset the machine no longer have to provide a dummy reset_cpu() function. The problem this solves is that some machines have external PMICs or similar to reset the system which have to be preferred over the internal SoC reset, because the PMIC can reset not only the SoC but also the external devices. To pick the right way to reset a machine each handler has a priority. The default priority is 100 and all currently existing restart handlers are registered with this priority. of_get_restart_priority() allows to retrieve the priority from the device tree which makes it possible for boards to give certain restart handlers a higher priority in order to use this one instead of the default one.
