* ARM: ep93xx: Move mach header files to include/mach/ep93xxSascha Hauer2023-03-066-613/+4
| | | | | | | | | | Currently arch specific headers can be included with longer possible as there won't be a single mach anymore. Move all ep93xx specific header files to include/mach/ep93xx/ to prepare for multi-arch support. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* clocksource: assign non-zero priorities to all clocksourcesAhmad Fatoum2022-04-251-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most barebox clocksources have a zero priority and if multiple of them exist, but no higher priority ones, the first to call init_clock wins. Some supported boards like the Raspberry Pi additionally depended on initcall ordering to favor one zero-priority clocksource over another. With the move to deep probe and with Commit b641580deb8c ("of: platform: Ensure timers are probed early"), device tree blob iteration order could now dictate which clocksource is ultimately used. This led to a 20 times slower clock source being chosen on the Raspberry Pi, because the ARM architected timer was taken instead of the bcm2835 timer. Fix the root cause by assigning priorities to all clocksource drivers. Priorities chosen are: 50: device_initcall 60: coredevice_initcall 70: postcore_initcall 80: core_initcall These priorities are all below 100, which was previously the lowest positive priority and as they are positive, they win against the dummy clocksource. This should ensure no priority inversion happens.

| * restart: replace reset_cpu with registered restart handlersSascha Hauer2015-08-271-7/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Hauer2013-08-161-24/+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>

* ARM ep93xx boards: switch to barebox_arm_entrySascha Hauer2013-02-043-11/+12
| | | | | | | | | | This architecture is a bit strange. It has up to four SDRAM banks, but all have a quite limited size. The SDRAM size for the different boards currently is unknown as it's configurable with Kconfig. We use a SDRAM size based on the value of the only board we have in the defconfigs: edb9301. This likely breaks other ep93xx boards. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * ARM: give boards control of the reset entry pointJan Luebbe2012-09-271-10/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | On some SoCs (for example AM35xx), the ROM bootloader passes useful information in r0 when jumping to barebox. To avoid overwriting this in the generic reset code, we introduce common_reset as a C function and as an assembler macro. This is then called form the reset entry point (either in common or in board code). This patch is based on code by Sascha Hauer <s.hauer@pengutronix.de>.
