* / ARM: Remove do_execute and thumb2_executeTrent Piepho2015-12-071-4/+1
|/ | | | | | | | | | | | | | | | | | | | 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>

| * edit: return error when save_file failedEnrico Jorns2015-11-051-2/+3
| | | | | | | | | | | | | | | | | | When writing a file failed (e.g. due to a read-only file system), no error was reported by the 'edit' tool. To be valid (and to not confuse the poor user) at least '1' should be returned to indicate an error.

| * edit: handle write() call errors in save_file()Enrico Jorns2015-11-051-3/+12
| | | | | | | | | | | | | | | | | | | | | | save_file() did ignore possible errors of its write() calls. Now the error code is used as return code for save_file(). write_full() is used instead of write() as it does not perform partial writes which would require to check for returned size, too.

| * of_dump: Add option to print node names onlySascha Hauer2015-10-261-2/+19
| | | | | | | | | | | | | | | | | | | | | | Devicetrees tend to become very long and it is hard to find the interesting nodes in a full tree output. This patch adds the -n option to the of_node command. With this option only the names of the nodes are printed, but not the properties. The resulting output is much shorter and the node one is interested in can be copy/pasted to a second call to of_node. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* | memtest: By default only test biggest regionSascha Hauer2015-11-041-27/+55
| | | | | | | | | | | | | | | | | | Often enough the biggest free region spans most free RAM, so it doesn't add much value to test the remaining free regions.

* | rework remap_rangeSascha Hauer2015-11-031-22/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | remap_range is for remapping regions with different cache attributes. It is implemented for ARM and PowerPC only, the other architectures only provide stubs. Currently the new cache attributes are passed in an architecture specific way and the attributes have to be retrieved by calls to mmu_get_pte_cached_flags() and mmu_get_pte_uncached_flags(). Make this simpler by providing architecture independent flags which can be directly passed to remap_range() Also provide a MAP_ARCH_DEFAULT flag and a arch_can_remap() function. The MAP_ARCH_DEFAULT defaults to whatever caching type the architecture has as default. the arch_can_remap() function returns true if the architecture can change the cache attributes, false otherwise. This allows the memtest code to better find out what it has to do. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * restart: replace reset_cpu with registered restart handlersSascha Hauer2015-08-271-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

This works because the providers (DIGEST_SHA1_GENERIC and DIGEST_SHA1_ARM) have a 'select SHA1'. However, consumers like the sha1sum command do a 'select SHA1' to enable SHA1 support. This of course does not work; selecting SHA1 will not select any of the SHA1 providers. This is broken for all digest consumers. We have to explicitly select a digest provider, that is DIGEST_*_GENERIC to enable the corresponding digest. This means now we will always have the generic digest in the binary, even when an optimized one is enabled. There is no sane way in Kconfig to "select provider for feature xy", so let's live with the overhead in the binary. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We used to have the login functionality in the /env/bin/init script. This is hard to review and it's too easy to break the login functionality with changes to this script. Move the places to ask for a password to C code where we have only a few places where we have to ask for a password. Mainly these are run_shell() and the menutree command. This patch introduces a login() function which will only return if the correct password has been entered. Following calls will return immediately without asking for a password again.
