* arch: refresh defconfigsSascha Hauer2016-10-121-16/+11
| | | | | | | | | | | | | | | | | | | | | | 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>

* 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 Hauer2015-08-272-32/+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.

* kbuild: move asm-offsets.h rule to ./KbuildMasahiro Yamada2015-01-081-0/+11
| | | | | | | | | | | | | | | 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.

* consistently use the same bitops.h fileSascha Hauer2014-07-171-13/+17
| | | | | | | | | | | | | | | | 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.

* x86: ns16550: Rework driver to allow for x86 I/O spaceMichel Stam2014-04-094-41/+4
| | | | | | | | | | | | The current implementation fakes a memory-mapped I/O device at 0x3f8 and 0x2f8, then uses platform read/write functions to do the actual reading and writing. These platform functions only exist for the x86 platform; better to move the I/O routines into the driver and have the driver request I/O ports using request_ioport_region.
