* bootm: introduce bootm_load_devicetree helperSascha Hauer2014-01-141-0/+2
| | | | Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* bootm: introduce bootm_load_initrd helperSascha Hauer2014-01-141-0/+1
| | | | | | | Make the bootm handlers simpler by factoring out an initrd load function. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* bootm: introduce bootm_load_os helperSascha Hauer2014-01-101-0/+2
| | | | | | | | | | 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>
* bootm: Replace getenv_loadaddr with getenv_ulSascha Hauer2013-10-071-2/+0

* bootm: Add dryrun supportSascha Hauer2013-09-241-0/+2
| | | | | | This adds support for checking the bootm command without actually booting. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* bootm: separate bootm input data and internal dataSascha Hauer2013-09-241-2/+14
| | | | | | | | | | | | We used to use struct image_data as the central data structure for bootm and also as the input data structure. This makes it unclear which of the fields are actually input data. This patch creates a struct bootm_data which is exclusively used for input data to make usage clearer. Also it moves the dispatching of multifile uImage pathnames to the core bootm code so that the core code gets more flexible and the command code simpler.

* bootm: move getenv_loadaddr from command to commonSascha Hauer2013-09-241-0/+2
| | | | | | | getenv_loadaddr may be used by other code, so move it from command/ to common/ Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* bootm: factor out code to make it usable from CSascha Hauer2013-06-191-0/+8
| | | | | | | Much of the bootm code is implemented in the command itself. Move it to a common place to be able to call it from C aswell. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* bootm: Pass unflattened devicetree to handlersSascha Hauer2013-03-061-0/+1
| | | | | | | | | This makes it possible to modify the tree in the handlers. This is necessary because the initrd addresses are only known inside the handlers, but not to the generic bootm code. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* booting: more flexible Linux bootargs generationSascha Hauer2012-05-141-0/+16
| | | | | | | | | | | | | | | | | | | | | | 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 Hauer2011-12-151-7/+55
| | | | | | | | | | | | | | 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>

* list: remove duplicated list.hSascha Hauer2009-11-031-1/+1
| | | | | | | | We accidently have two list implementations in the tree: include/list.h and include/linux/list.h. This patch moves the latter (newer one) to include/linux/list.h. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* cleanup do_bootm_linux()Robert Schwebel2007-11-281-2/+4
| | | | | | | | This patch cleans up the do_bootm_linux() function. It removes most of the uggly ifdefery and replaces it by a sane function optimizing structure. Signed-off-by: Robert Schwebel <r.schwebel@pengutronix.de>
