Add pinctrl, clock drivers and SPL to support the IPPQ5210 SoC in U-Boot.
The relevant DT files are available in linux-next [1].
Working features, as tested on RDP504:
* Serial console
* UART
* MMC
* Boot sequence transitions from Boot ROM to U-Boot SPL, proprietary
binaries (a.k.a QCLib) load and execute as appropriate and eventual
jump to U-Boot.
* The QCLib handles
- DDR initialization
- Clock setup

v6: - Move binman related changes to separate series, so that the
SPL changes can move forward.
- Restore v3 build steps for now
v5: - Reorganize SPL related code into common and SoC specific functions
to allow SoCs to customize according to their boot flow
- Fix documentation related build errors
- Please see the patches for specific changes
-
https://lore.kernel.org/u-boot/[email protected]/
v4: - Add binman based image creation support instead of special scripts
- Identify boot media based on PBL shared info instead of CONFIG_xxx
- Address v3 feedback (see individual patch for details)
-
https://lore.kernel.org/u-boot/[email protected]/
v3: - Move stack range
- Split spl.c patch
- Move documentation towards the end of the series
- Pick couple of R-b
-
https://lore.kernel.org/u-boot/[email protected]/
v2: - Add QCOM_GENI_MINICORE config option
- Move minicore register settings to separate file and include
if QCOM_GENI_MINICORE is enabled
- Remove bootph-all from override dts and moved them to kernel
