* Blackfin: Remove architectureSascha Hauer2019-09-1222-2442/+0
| | | | | | | Blackfin is dead and already removed from the Kernel. Remove it from barebox as well. RIP. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* include: Move bulk of boot.h to bootm.hSascha Hauer2016-07-261-0/+1
| | | | | | | | The majority of the stuff currently in include/boot.h is about bootm code implemented common/bootm.c. To be more consistent move it to a new file include/bootm.h. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* bootm: Push dryrun to handlersSascha Hauer2016-01-261-0/+3
| | | | | | | We can make the dryrun option more useful by calling into the handlers. With this we can detect more cases that can go wrong during boot. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* restart: replace reset_cpu with registered restart handlersSascha Hauer2015-08-272-4/+14
| | | | | | | | | | | | | | | | | | | | | | 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.

* blackfin: consolidate arch/blackfin/include/asm/linkage.hMasahiro Yamada2015-02-021-1/+1
| | | | | | | | | | | | | | | | | | | Since include/linux/linkage.h includes <asm/linkage.h>, the basic coding style we should follow is: - <linux/linkage.h> should contain default macro defines - <asm/linkage.h> can define arch-specific macros and override the default ones in <linux/linkage.h> The arch/blackfin/include/asm/linkage.h has redundant defines that are already defined in <linux/linkage.h>. Replace it with the one imported from Linux 3.19-rc6. Generally, <asm/linkage.h> should not be included directly. Fix two files to include <linux/linkage.h> instead.

* kbuild: move asm-offsets.h rule to ./KbuildMasahiro Yamada2015-01-081-0/+12
| | | | | | | | | | | | | | | 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.

* bootm: introduce bootm_load_os helperSascha Hauer2014-01-101-2/+4
| | | | | | | | | | 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. Instead, introduce a helper to load the os after the handlers have figured out a good load address. 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>
* bootm: use new uimage codeSascha Hauer2011-12-151-4/+8
| | | | | | | | | | | | | | This switches the bootm code to the new uimage code. Also bootm can now handle other types of images than uImages. Currently the only architecture making use of this is arm which allows to boot zImages, raw images and barebox images. I intended to make a more bisectable series from this but I failed becuase there are many dependencies and no matter how I tried the patches grew bigger and and bigger. So I decided to put this all in a single patch. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* fix malloc space sizesSascha Hauer2011-12-031-1/+1

* bootm: push relocate_image up to the generic commandSascha Hauer2011-11-291-3/+0
| | | | | | | | | All handlers used to just relocate the image without any checks, so we are doomed if we write outside of SDRAM or will overwrite ourselves. Move the relocation up to the generic part where we have a chance of catching these issues. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
