* 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>

* Treewide: remove address of the Free Software FoundationSascha Hauer2012-09-1715-68/+0
| | | | | | | The FSF address has changed in the past. Instead of updating it each time the address changes, just drop it completely treewide. 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
| | | | | | end is start + size - 1, not start + size. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* 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>
* rename include/mem_malloc.h to include/memory.hSascha Hauer2011-09-231-1/+1
