| * stm32mp: init: fix up st, package into stm32mp pinctrl nodesAhmad Fatoum2020-05-121-15/+48
| | | | | | | | | | | | | | | | | | | | | | Since Linux v5.1, the pinctrl driver can use the st,package property if provided to validate whether the ball to be configured exists on the package. The upstream device trees provide this property, but if we'll want barebox to supply it instead, so we can use the same barebox binary for different SoC variants.

| * ARM: stm32mp: init: detect Revision Z and 800 MHz profilesAhmad Fatoum2020-05-082-6/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Revision A was 0x1000 and B was 0x2000, so I assumed the next would be revision C valued 0x3000. Alas, it's revision Z with 0x2001... Change the code accordingly and add detection for the new 800Mhz profiles. Code taken from U-Boot commit cf0818b477 ("stm32mp1: support of STM32MP15x Rev.Z") and Patch[1] "stm32mp1: add 800 MHz profile support".

The device tree is based on the one in linux-stm32/stm32-next, which will probably be merged for Linux v5.8-rc1. Instead of waiting that long, we import it here with some stuff removed/changed, so it's usable for both barebox and Linux, without the prerequisite patches. The non-barebox specific parts have been moved into separate DTSIs (arch/arm/dts/stm32mp{157c-lxa-mc1,15xx-osd32}.dtsi), so both can be dropped after the v5.8-rc1 sync with only include path change necessary in arch/arm/dts/stm32mp157c-lxa-mc1.dts.

In the same commit, upstream set the compatible to "arm,arm-firmware-suite", which barebox does not know about. Adapt our fixed partition setup accordingly by wrapping all partitions in an extra "partitions" node with the correct compatible.

Similarly, `mw 0x20d8040 0x00000020; mw 0x20d8044 0x10000000; reset` forces an i.MX6UL into recovery mode after reset.

This is because the BootROM reads the boot mode out of SRC_GPR9 instead of SRC_SBMR1 whenever SRC_GPR10 has its 28th bit set.
