Hi Krzysztof,

Thanks for pointing this out. You are absolutely right to question the
Reviewed-by tags.

As this is my first time submitting a patch series of this size, I
misunderstood the requirements for the Reviewed-by tag and mistakenly
thought an internal review was sufficient. I apologize for the confusion
and will remove the unconfirmed tags in v2.

Our corporate domain is actually axera-tech.com. I now realize the
vendor prefix should reflect the domain name. I will change the prefix
to "axera-tech,.*" in v2 to comply with the guidelines.

[PATCH 0/6] arm64: Introduce Axera AX650 SoC and AX650 Demo board

[Leng Honglin]

Axera AX650 is an Arm64 SoC developed by Axera Semiconductor. The
AX650 Demo board is based on the AX650 SoC and provides the hardware
platform used to validate this series.

This series adds the initial upstream support required to build and
boot the Linux kernel on the AX650 Demo board.

The initial platform support includes:

- Axera AX650 SoC and AX650 Demo devicetree bindings
- ARCH_AXERA arm64 platform selection
- arm64 defconfig support
- Cortex-A55 CPUs and PSCI
- GIC-400 interrupt controller
- ARMv8 architectural timer
- Cortex-A55 PMU
- UART console
- 8 GiB system memory
- Axera ARM64 SoC maintainer information

The patches are organized as follows:

- Patch 1/6: Add the Axera vendor prefix.
- Patch 2/6: Add devicetree bindings for the AX650 SoC and
  AX650 Demo board.
- Patch 3/6: Add the ARCH_AXERA arm64 platform option.
- Patch 4/6: Enable ARCH_AXERA in the arm64 defconfig.
- Patch 5/6: Add the initial devicetree description for the AX650 SoC
  and AX650 Demo board.
- Patch 6/6: Add Axera ARM64 SoC entries to MAINTAINERS.

The series is intentionally limited to the minimum platform support
required to boot the board with a serial console. Additional
peripherals will be added in subsequent patches.

The platform was tested on an AX650 Demo board using the vendor boot
chain to load the kernel and device tree. A kernel with an embedded
initramfs successfully reached an interactive shell on the serial
console, and all 8 CPUs were brought online.

Where did it happen and what was here exactly reviewed? Did reviewer
understand statement of oversight? I am asking because this is v1 and
has already clearly visible issue (below).
