[PATCH v2 0/9] MIPS: Ingenic: Add XBurst / XBurst II infrastructure and improve overall Ingenic SoC support

["H. Nikolaus Schaller" <hns@goldelico.com>]

PATCH V2 2026-11-12 09:10:31:
The series updates the Ingenic platform support to allow clean transitions
between bootloader-provided Device Trees and built-in fallbacks. It provides
the foundational Kconfig, PRID, and CPU-probe blocks required for newer 
Ingenic/Lumissil hardware generations (X1600, X2000, X2600) and adds JZ4730
for completeness.

Changes to V1
- allow user selection of BUILTIN_DTB (suggested by Paul Cercueil <paul@crapouillou.net>)
- added the CPU_XBURTS2 type here to solve an issue reported by kernel test robot
- removed PRID_IMP_XBURST2_R2 and merged into single commit
- reviewed all PRID_IMP with data sheets and programming manuals
- added full x2600 and jz4730 definition for completeness
- added platform makefile and load address for X1600, X2000, X2600

PATCH V1 2026-10-25 20:20:55:
The series updates the Ingenic platform support to allow clean transitions
between bootloader-provided Device Trees and built-in fallbacks. It provides
the foundational Kconfig, PRID, and CPU-probe blocks required for newer 
Ingenic/Lumissil hardware generations (X1600, X2000, X2600).

The first patch corrects an inverted Kconfig condition regarding appended 
and built-in DTBs. This fix is necessary to allow configurations where 
the kernel relies entirely on a Device Tree provided dynamically by the 
bootloader instead of forcing a built-in fallback.

The remaining patches implement CPU-probe initialization, correct PRID 
mappings (including vendor-kernel values for the Ingenic A1 SoC), 
platform load addresses, Kconfig updates, and generic board match updates.

Structure of the series:
1. MIPS: Ingenic: Fix inverted MIPS_NO_APPENDED_DTB logic in Kconfig
2. MIPS: Ingenic: Add and update PRIDs for XBurst II R0 and R2
3. MIPS: Ingenic: Expand Kconfig for X1600, X2000, and X2600 SoCs
4. MIPS: Ingenic: Add cpu-probe setup for XBurst and XBurst II R2
5. MIPS: generic: Add MACH_INGENIC type and compatible for X1600
6. MIPS: Ingenic: Add Platform makefile for X1600 and X2000

Testing:
The series has been compile-tested for generic Ingenic targets. PRID 
values for jz4780, x1600, X2000, X2600 were verified on real hardware 
(CI20, LX16, LX20 and LX26 boards respectively).

Please review and consider for inclusion.
