* clk: select CLKDEV_LOOKUP from COMMON_CLKAhmad Fatoum2024-01-191-1/+0
| | | | | | | | | | All platforms that select COMMON_CLK also select CLKDEV_LOOKUP, therefore just select it in drivers/clk/Kconfig and drop the CLKDEV_LOOKUP all over the place.

* ARM: zynq: Move mach header files to include/mach/zynqSascha Hauer2023-03-067-261/+2
| | | | | | | | | | Currently arch specific headers can be included with longer possible as there won't be a single mach anymore. Move all zynq specific header files to include/mach/zynq/ to prepare for multi-arch support. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* arm: avnet zedboard: Use compressed DTBSascha Hauer2022-12-161-0/+1
| | | | | | | The barebox image is limited to the OCRAM size, so squeeze the binary size a little bit by using compressed DTB. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* bootsource: rename existing bootsource_set to bootsource_set_rawAhmad Fatoum2022-08-091-1/+1
| | | | | | | | | | | | | | | | | Patterns like [ "$bootsource" = mmc ] && boot mmc$bootsource_instance expect that ${bootsource_instance} and MMC aliases align, which may not always be the case. In preparation for adding a new bootsource_set function that consults an optional mapping table from bootrom bootsource_instance to board-specific device numbering, rename all existing instances to bootsource_set_raw. While at it, clean up the legacy split into bootsource_set and bootsource_set_instance and have the new bootsource_set_raw accept both arguments at once. No functional change intended.

* bootm: propagate register_image_handler return valueAhmad Fatoum2020-10-071-3/+1
| | | | | | | | | While register_image_handler can't currently fail, it still returns an error code. Propagate that error code along instead of having a blanket return 0.

* ARM: zynq: zed: partially revert zynq_cpu_lowlevel_init() chnagesLucas Stach2020-01-141-2/+0
| | | | | | | | | | | | | Calling arm_cpu_lowlevel_init() from zynq_cpu_lowlevel_init() adds a stack push/pop to the latter function which doesn't work this early in the boot. As the BootROM apparently hands proccessor control to us in abort(!?!) mode, setting up a stack requires duplicating most of arm_cpu_lowlevel_init(). To get around this catch-22 move the call to arm_cpu_lowlevel_init back into the board lowlevel start function, so we don't need a stack at all.

| | | | | | | | | | Instead of generating a suitable image header with linker magic, move all of this into zynq_mkimage. The configuration file format and parsing is based on imx-image.

* restart: replace reset_cpu with registered restart handlersSascha Hauer2015-08-271-11/+13
| | | | | | | | | | | | | | | | | | | | | | 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.

* Set model and hostname at boardlevelSascha Hauer2013-08-161-3/+0
| | | | | | | | | | | | With multiboard support the compiletime generated BOARDINFO string gets more and more meaningless. This removes it from Kconfig and replaces it with a variable that can be set at boardlevel. Also many boards have a standard setting for the hostname in the environment. This patch also moves the standard to C code by calling barebox_set_hostname(). Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
