* PPC: request a consistent memory layoutJuergen Borleis2017-05-112-1/+18
| | | | | | | | | | | | | Using the memory test command will crash barebox, because it tests the area where the stack is located for the PPC architecture. On PPC the stack is below the barebox binary. Below the stack the malloc area is located. Until this change some routines used the macros from 'memory_layout.h', some other calculated their values by their own - which resulted into an unrequested and unprotected stack area.

* arch: refresh defconfigsSascha Hauer2016-10-125-161/+108
| | | | | | | | | | | | | | | | | | | | | | The defconfig files are long untouched and a make xy_defconfig; make savedefconfig usually generates quite a different looking file. Refresh them to make it easier to generate patches against the configs using make xy_defconfig; make menuconfig; make savedefconfig This has been done with the following script. for a in arch/*; do arch=$(basename $a) for c in $a/configs/*; do config=$(basename $c) export ARCH=$arch make $config && make savedefconfig && mv defconfig $c done done Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * defaultenv: add defaultenv-1 in boards via defaultenv_append_directory()Sascha Hauer2016-10-1021-5/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently it's hardcoded for each board which defaultenv version is used. This is unfortunate since some people like the other defaultenv version better and may want to select it. This patch removes the board specific environment path CONFIG_DEFAULT_ENVIRONMENT_PATH and instead adds it via: if (IS_ENABLED(CONFIG_DEFAULT_ENVIRONMENT_GENERIC)) defaultenv_append_directory(defaultenv_<board>); This way we can make sure that the defaultenv-1 board specific bits are only compiled in when defaultenv-1 is actually in use. The next step is to make the defaultenv version selection a user visible choice. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * bootm: Move bootm options to common/KconfigSascha Hauer2016-05-103-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | bootm has a C API, so the bootm options have to depend on the option providing the bootm code (CONFIG_BOOTM), not on the option providing the command (CONFIG_CMD_BOOTM). Fixing the dependencies makes it possible to fully use bootm from C without enabling the bootm command support. This also removes the CMD_ prefix from the options which means we have to update the defconfigs aswell. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* rework remap_rangeSascha Hauer2015-11-032-29/+21
| | | | | | | | | | | | | | | | | | 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 Hauer2015-08-273-6/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

It's not easy to find a correct value for this register, it seems it depends on the used external reference frequency and some other 'magic' things. There are some values out in the wild for the 33,333333 MHz and 33,333000 MHz reference frequency case, but they are not consistent over the boards. The value used here in this change for the USB PLL register is from the first days of support for this platform and works at least on the reference baseboard.
