* ARM: duckbill: Check machine type in initcallsSascha Hauer2019-10-021-0/+6
| | | | | | | Check for the right machine type in initcalls before executing them to make the board multi image safe. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: MXS: make power levels configurable in mx2*_power_initRoland Hieber2018-08-141-1/+1
| | | | | | | | | | | | | Depending on the application, board code might want to configure different power levels and brownout thresholds. They can do so now with an additional struct mxs_power_ctrls* parameter to mx2*_power_init. Note that VDDMEM was not set up explicitely in mx28_power_init, but can now be configured. However, mx28_power_default->vddmem is NULL, so the old behaviour is still the case when using those default values.

* ARM: MXS: refactor mx2*_power_init source configurationRoland Hieber2018-08-141-1/+1
| | | | | | | | | | | | Having three ints as parameter suggests that we can use up to 2^3 power configurations for the system, but when we look at the code, the power setup is packaged in if {...} else if {...} else if {...} blocks, so setting more than one parameter to 1 is useless here. Refactor the parameters into an enum to get rid of that suggestion. Signed-off-by: Roland Hieber <r.hieber@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: MXS: allow configuration of EMI clock prescalerRoland Hieber2018-08-141-0/+2
| | | | | | | | | | | | | Allow to set not only the fractional divider, but also the prescaler for the EMI clock in mxs_mem_init_clock(), and rename the parameters accordingly to reflect the change. Port the existing board code to set up the EMI clock explicitely with the old values. Also fix the off-by-a-half error in the comments, which did not take the prescaler of 2 into account, on which the fractional divider is applied (according to the i.MX23/i.MX28 Reference Manuals) Signed-off-by: Roland Hieber <r.hieber@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: MXS: i.MX28: allow setup of low-voltage SDRAMRoland Hieber2018-08-141-1/+2
| | | | | | | | The PINCTRL_*_DDR_MODE_* defines are now needed in global scope, so move them to the respective include header. Signed-off-by: Roland Hieber <r.hieber@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: return positive offset in get_runtime_offset()Sascha Hauer2018-03-211-1/+1
| | | | | | | | | | | When we are linked at 0x0 and running at 0x01000000 then get_runtime_offset() should return 0x01000000 and not 0xff000000. This makes get_runtime_offset() more consistent and better understandable. This was tested on a Freescale i.MX53 Quickstart board. Additionally relocate_to_adr() was tested since that is normally not called. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* ARM: mxs: add parameter to mx28_mem_init to allow custom memory configUwe Kleine-König2016-05-101-1/+1
| | | | | | | | | | Rename the already global array of default memory settings to make the intended usage more obvious. Also make generous use of the const keyword. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
