* rework remap_rangeSascha Hauer2015-11-031-13/+1
| | | | | | | | | | | | | | | | | | 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 Hauer2015-08-271-2/+10
| | | | | | | | | | | | | | | | | | | | | | 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.

* dma: Use generic place for dma_addr_t typedefSascha Hauer2015-05-221-3/+0
| | | | | | | | | Instead of letting all architectures define their own dma_addr_t use a common place in include/linux/types.h and use a Kconfig symbol that architectures can select to define the width of dma_addr_t. The same is done in the Kernel. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* kbuild: move asm-offsets.h rule to ./KbuildMasahiro Yamada2015-01-081-0/+22
| | | | | | | | | | | | | | | Currently, MIPS is the only architecture that needs include/generated/asm-offsets.h, but we have got ./Kbuild file now. It is a good reason to move asm-offsets.h rule from arch/mips/Makefile to ./Kbuild and add dummy asm-offsets.c for the other architectures. asm-offsets.h would be useful for all the architectures. This commit does not implement include/generated/bounds.h, but if necessary, it is easy to implement it.

* sandbox: allow "make ARCH=sandbox allyesconfig"Holger Schurig2014-07-221-0/+1
| | | | | | | | | | | | | Compiling the tree with allyesconfig is helpful because different compilers (gcc, clang) or static checkers (e.g. clang's scan-build) can then process and check more code. This patch introduces two new configuration symbols that Kconfig files can depend on. That way, code that is only working where a cache or DMA implementation exists can be opted out.

* consistently use the same bitops.h fileSascha Hauer2014-07-172-3/+30
| | | | | | | | | | | | | | | | We have many variants of the same bitops.h file. Consistently use the same file for all architectures which completely use the generic bitops versions. Some architectures had static inline versions of functions identically to the generic versions, these are removed and the generic versions are used directly now. Also several architectures depend on the generic find_*_bit functions but didn't have the GENERIC_FIND_NEXT_BIT Kconfig option selected. This is added where needed.

| | | | | | | | | | The common bootm code used to load uImage contents to SDRAM before calling into the handlers if possible. This makes the handlers complicated since they have to handle many cases.

* Set model and hostname at boardlevelSascha Hauer2013-08-162-3/+3
| | | | | | | | | | | | With multiboard support the compiletime generated BOARDINFO string gets more and more meaningless. This removes it from Kconfig and replaces it with a variable that can be set at boardlevel. Also many boards have a standard setting for the hostname in the environment. This patch also moves the standard to C code by calling barebox_set_hostname(). Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | Storing the size instead of the resource end in struct resource was a mistake. 'size' ranges from 0 to UINT[32|64]_MAX + 1 which obviously leads to problems. 'end' on the other hand will never exceed UINT[32|64]_MAX. Also this way we can express a iomem region covering the whole address space. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* booting: more flexible Linux bootargs generationSascha Hauer2012-05-141-1/+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>

Currently the only architecture making use of this is arm which allows to boot zImages, raw images and barebox images.
