Now, barebox has/can be loaded like a normal image, so the filesize, that is written to the barebox header, can be evaluated.

| * Documentation: zii-vf610-dev: Add necessary post reset delayAndrey Smirnov2019-06-261-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As observed on CFU1 board, without this delay we interrupt mask ROM code execution even before it sets up any PLLs correctly preventing Barebox from correctly starting up. Fixing this by adding PLL setup code to OpenOCD script helps somewhat and Barebox starts, howerver CPU started this way ends up being unstable crashing randomly during further Barebox use. Adding a simple 100 ms post reset delay resolves all of the described issues. This is also consistent with how other ZII boards are set up.

Adjust psci_system_off to use ->system_off instead.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds driver support for the 12 GPIO banks on the STM32MP157. As they are accessible to both the Cortex-A cores as well as the Cortex-M core, modifications to these are protected by a hardware spinlock and clocks are enabled/disabled as required. All register fiddling done by the driver is collected in <soc/stm32/gpio.h>, so future PBL code may make use of it as well to chainload barebox proper.

| * | driver: add stubs for hardware spinlocksAhmad Fatoum2019-06-201-0/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some STM32MP Linux drivers, which could be ported to barebox as part of improved second stage barebox support, are using hardware spinlocks to coordinate access between the three processors. While barebox only uses one of the two Cortex-A cores, spin locks may still be necessary because of firmware loaded unto the Cortex-M. To ease porting these drivers, without having to import the hw spinlock driver now, add stubs for the functions. The stubs will we be reused when CONFIG_HWSPINLOCK is introduced, but is disabled in config. The API is oriented after the implementation in U-Boot.

| * | gpiolib: add gpio_get_chip helperAhmad Fatoum2019-06-202-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Pinctrl nodes adhering to the generic pinctrl bindings may contain properties like input-low/input-high, which require pinctrl_ops.set_state to have a handle on the relevant gpio chip. Currently this would lead to code duplication: Both the pinctrl driver and gpiolib will need to store a list of registered gpiochips. Avoid this by providing a helper to query the registered gpio_chip given a gpio's number. Signed-off-by: Ahmad Fatoum <a.fatoum@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
