* restart: replace reset_cpu with registered restart handlersSascha Hauer2015-08-271-1/+2
| | | | | | | | | | | | | | | | | | | | | | 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.

* 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>
* ppc: bootm: relocate fdt to valid boot memoryRenaud Barbier2013-09-091-1/+48
| | | | | | | | | | | | | | For the MPC85xx family of SOCs Linux expects any boot firmware information to be passed in the first 64MiB of memory. This adds support to ensure that the device tree is relocated to a valid location if it is outside that address range. For the other SOC family currently present in the ppc architecture, the default is not to relocate as at Linux startup the virtual address equals the physical address.

* bootm: Pass unflattened devicetree to handlersSascha Hauer2013-03-061-0/+8
| | | | | | | | | 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>

| * bootm: use new uimage codeSascha Hauer2011-12-151-9/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* 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>
