* | | ARM: pxa: pxa2xx use PSPR for resume addressRobert Jarzmik2015-12-072-2/+2
| |/ |/| | | | | | | | | | | | | | | | | | | Both lubbock and mainstone suspend to RAM were broken by the same typo. The linux kernel saves the resume address to PSPR, ie. the scratch pad register, while it was PSSR which was checked in barebox. Fixing this typo was tested on mainstone where resume from S3 works.

* | ARM: Fix bug in remap_rangeSascha Hauer2015-11-131-16/+22
| | | | | | | | | | | | | | | | | | | | | | remap_range takes generic MAP_CACHED/MAP_UNCACHED flags which are then translated into the corresponding ARM specific bits. We call remap_range internally from dma_alloc_* aswell, but instead of passing the generic flags we pass the ARM specific bits. Fix this by creating an internal __remap_range function which takes the ARM specific bits and use it where appropriate. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * scripts/kwbimage: Make BINARY files relative to config fileSascha Hauer2015-10-194-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | The BINARY files given in the config files are expected to be relative to the place kwbimage is called from. This is bad since it breaks where kwbimage is called from the build directory and not the source directory. It makes more sense to make the paths in the config files relative to the config files which works with out of tree builds and is also more what a user normally expects.

| * | arm: Disable unaligned accessesAndrey Smirnov2015-10-151-0/+7
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From reading ARM architecture related documentation if appears that while unaligned memory access is supported by the processor in general it is not supported if MMU is disabled. The problem in question can be easily reproduced by building the code without this patch, MMU disabled, and trying to run 'memtest' command. Which would in turn call mem_test() which would eventually call show_progress(). That last function, if build without -mno-unaligned-access would result in unaligned memory access which would result in Barebox hanging. This patch instructs the compiler to not generate any unaligned accesses to memory thus avoiding the problem.

| * | | rework remap_rangeSascha Hauer2015-11-0310-139/+48
| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the current multi image build process the DTBs end up uncompressed in the PBL. This can be annoying because the PBL is often very size constrained. This patch allows to put the DTBs in as lzo compressed binary into the PBL. Since lzo offers quite good compression ratios for DTBs no other compression algorithm has been implemented for now. Boards which want to use the compressed DTBs only have to change the __dtb_ prefix in the DTB name to __dtb_z_. Also they should select ARM_USE_COMPRESSED_DTB to make sure barebox supports uncompressing the DTB. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

This was controlled by the config option DEFAULT_ENVIRONMENT. However, that option turns on compiling the env into the barebox binary itself, as a backup if the in flash env can't be loaded. Most other boards have in flash env support unconditionally. But omap and socfpga also have xloader configurations, which aren't supposed to have environment support, either in flash or compiled in. If the in flash env code were unconditional, then the xloaders would gain it. So the code depends on ENV_HANDLING, which is only set on those boards that are supposed to have an in flash env and not set on all the boards that aren't supposed to have it. If someone wanted to create a board that did have a saved env, but used an alternate to this generic omap/socfpga file in FAT method, then they'd probably want to create a new config option to control this code and have it not be enabled for their board.

| * xload: be more flexible when searching for second stage bootloader.Vicente Bergas2015-10-021-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A first stage bootloader can read fat and ext4 filesystems, and even both can be compiled-in at the same time. But then xload has a hardcoded fat filesystem mount option which renders ext4 unusable. This patch tries to mount it as ext4 if the fat attempt fails. Then, a typical use case of an ext4 formatted filesystem is it to be a standard linux filesystem, which contains boot-related files in /boot. So, when searching for the second stage bootloader, try /boot/barebox.bin after not finding it in /barebox.bin Signed-off-by: Vicente Bergas <vicencb@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
