Add pinctrl, clock drivers and SPL to support the IPPQ5210 SoC in U-Boot.
The relevant DT files are available in linux-next [1] & [2]
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

v9: - Address review feedback
- Move qclib handling to separate file with some functionality as
'weak' functions to allow SoC implementations to override it
- Link to v8:
https://lore.kernel.org/u-boot/[email protected]/
v8: - Rebased on
https://source.denx.de/u-boot/custodians/u-boot-snapdragon.git
- Address Casey's review comments on v6
- Spin off GENI Minicore support and mkmbn support as separate patches
[PATCH] misc: qcom_geni: Add minicore support - [a]
[PATCH 0/3] tools: qcom: mkmbn: Updates to support ipq5210 - [b]
- Re-organize the functions from spl.c into board_spl.c and
fit-handler.c
and remove spl.c
- Retained R-b tags since the code just moved
- Removed references to MBN and multi-elf creation steps in rdp.rst
since
mkmbn.py takes care of it
- Add details about the interface table in
doc/board/qualcomm/spl-qclib.rst
- May need to update config.mk based on the final shape of mkmbn
patches [b]
a - https://patchwork.ozlabs.org/project/uboot/list/?series=514770
b -
https://lore.kernel.org/u-boot/[email protected]/
v7: - Fix inadvertant typo in doc/board/qualcomm/rdp.rst
- Pick multiple R-b tags
- No code changes
v6: - Move binman related changes to separate series, so that the
SPL changes can move forward.
- Restore v3 build steps for now
-
https://lore.kernel.org/u-boot/[email protected]/
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
