* restart: replace reset_cpu with registered restart handlersSascha Hauer2015-08-271-3/+5
| | | | | | | | | | | | | | | | | | | | | | 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.

* ARM: OMAP: remove unused CONFIG_OMAP3_CLOCK_CONFIG optionSascha Hauer2015-06-221-5/+0

* ARM: OMAP: Safe boot info in fixed SRAM addressSascha Hauer2013-12-101-1/+2
| | | | | | | | | | | | | Storing the boot information in the image itself and passing a pointer around between images is cumbersome and doesn't fit well with multiimage support where the pointer we pass around is already occupied by the devicetree. Do the same as U-Boot does and store the boot information at the bottom of the SRAM public stack. To maintain the compatibility between new xloaders and older barebox binaries we still pass the boot information to the next stage via pointer. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: OMAP: centralize omap startupSascha Hauer2013-11-221-2/+12
| | | | | | | | | This introduces a single omap_init function which detects the SoC and does all further SoC initialization. This is done to get rid of initcalls without proper SoC protection. The same has been done for i.MX already. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* arm: omap: store boot source info from ROM loaderTeresa Gámez2013-07-101-3/+13
| | | | | | | | | | | | | | | | | | The ROM loader passes the address of a buffer to the MLO in register 0. Store this data so we can find the boot source later. On the same way the bootinformation are passed to the barebox, then. It has to be enshured that r0 contains always the buffer or the boot source detection will not work. Applied this on all OMAPs. This patch is based on work of Jan Luebbe <jlu@pengutronix.de>. Compile tested on all OMAP boards. Tested on pcm049, phyCARD-A-L1 and pcm051.
