* treewide: add MODULE_DEVICE_TABLE markersAhmad Fatoum2023-06-132-0/+2
| | | | | | | | | | | | | | | | Syncing device trees with Linux upstream can lead to breakage, when the device trees are switched to newer bindings, which are not yet supported in barebox. To make it easier to spot such issues, we want to start applying some heuristics to flag possibly problematic DT changes. One step towards being able to do that is to know what nodes barebox actually consumes. Most of the nodes have a compatible entry, which is matched by an array of of_device_id, so let's have MODULE_DEVICE_TABLE point at it for future extraction.

| | | | | | | | | | | | Including <stdio.h> for printf is a bit problematic, because it pulls in other headers for <console.h>, which includes quite a few more headers as well.

* dove: move memory controller remapping before RAM detectionUwe Kleine-König2018-05-312-22/+29
| | | | | | | | | | | | | | | | | | Compared to other mvebu cpus the memory controller registers are in their own register window that can be moved independently of the mbus register window. Since commit f05c6e095cf8 the available RAM configured by the boot ROM is read out earlier. This happens to be before the memory controller register window is moved and so dove_memory_find() fails. To fix this move the memory controller window together with the mbus window. This change allows to boot barebox first stage again on a Solidrun Cubox.

* mvebu: get initial position of register window from image headerUwe Kleine-König2017-03-023-3/+74
| | | | | | | | | | | | | | | A problem when using 2nd stage booting on mvebu is that the first bootloader already switched the register window location from 0xd0000000 to 0xf1000000 by writing to 0xd0000080. When the second bootloader also tries to do this switch it writes to the wrong location resulting in an exception and so a boot failure. For this reason the base address of the register window is passed in the barebox header and picked up from there by early code. In a further patch bootm is taught to put the actual position of the window there for the second bootloader to finally make second stage booting work.

* mvebu: rework how memory is detectedUwe Kleine-König2017-02-168-182/+124
| | | | | | | | | | | | | | Status quo is that initially a size of 64 MiB is assumed (which is also used to determine the size of the malloc area) and then later the dtb is fixed up with the actually available RAM which is then used. Instead detect the real RAM size earlier and don't fixup the device tree. The device tree is fixed up instead by generic code. This way the malloc area is more appropriately sized and RAM detection is more similar to mach-imx which is both nice.

* restart: replace reset_cpu with registered restart handlersSascha Hauer2015-08-275-26/+15
| | | | | | | | | | | | | | | | | | | | | | 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.
