[v6] Add Axiado SoC AX3000 and EVK board

[PATCH v6 0/8] Add Axiado SoC AX3000 and EVK board

Posted by Kuan-Jui Chiu 1 month ago

This patchset introduces Axiado SoC AX3000 and a EVK SCM3003 for emulation
The model for Axiado SoC AX3000 supports
  4 Cortex-A53 CPUs
  Arm Generic Interrupt Controller v3
  4 Cadence UARTs
  1 SDHCI controller with PHY
  8 Cadence GPIOs

Verified the machine "axiado-scm3003" with following command

qemu-system-aarch64 \
    -m 4G \
    -machine axiado-scm3003 \
    -device loader,file=u-boot.bin,addr=0x3C000000,cpu-num=0 \
    -nographic \
    -serial null \
    -serial null \
    -serial null \
    -serial mon:stdio \
    -drive if=sd,file=obmc-phosphor-image-evk-axiado-qemu.wic,format=raw

  3. Follow C99 standard to declare variable in for-loop
  4. Remove comment "TBD" from empty function
  5. Define marco for bit definition in axiado_sdhci
  6. Move object_initialize_child() to instance_init() from realize() in
     axiado_sdhci
  7. Remove callback of get_default_cpu_type() from ax3000-soc and set
     type of CPU to A53
  8. Update the command to run "axiado-scm3003" in QEMU

Changes in v2:
  1. Move axiado-* to ax3000-* in hw/arm and include/hw/arm
  2. Add axiado_sdhci to support AXIADO_SDHCI
  3. Move implementation for eMMC PHY device to axiado_sdhci

This causes 'make check' to fail. Please test this kind of
thing before submission.

Hint: running QEMU without any other arguments crashes:
 qemu-system-aarch64 -machine axiado-scm3003

Hi PMM

Does you mean this patch set is not buildable or it must be passed 
without any other arguments?

QEMU would crash without -drive argument which SoC created an eMMC 
device by default

If the machine must be able to run without any other argument, I will 
fix it in v7

I mean that the code you add must not cause our standard
test suite (which you can run with "make check" and
"make check-functional") to fail. One of the things it does
involves running every board model with no extra arguments.

More generally, regardless of what command line arguments the
user gives, QEMU should not crash. If the arguments don't
make sense, report an error message.

Got it.
I will run the "make check" and "make check-functional" then fix all of 
the problems in v7 to pass the test
