Re: [PATCH 0/6] Enable Cubieboard A10 boot SPL from SD card

[Niek Linnenbank]

Hello Strahinja,

Thanks for contribution these patches, and also taking the H3 into account :-)

I've ran the avocado based acceptance tests for both boards and got these results:

$ ARMBIAN_ARTIFACTS_CACHED=yes AVOCADO_ALLOW_LARGE_STORAGE=yes ./build/tests/venv/bin/avocado --show=app,console run -t machine:orangepi-pc tests/avocado/boot_linux_console.py

...

RESULTS    : PASS 5 | ERROR 0 | FAIL 0 | SKIP 0 | WARN 0 | INTERRUPT 0 | CANCEL 0
JOB TIME   : 114.24 s

$ ./build/tests/venv/bin/avocado --show=app,console run -t machine:cubieboard tests/avocado/boot_linux_console.py

...

RESULTS    : PASS 2 | ERROR 0 | FAIL 0 | SKIP 0 | WARN 0 | INTERRUPT 0 | CANCEL 0
JOB TIME   : 22.79 s

So that shows both machines are still running fine. During startup of the bionic 20.08 image for orangepi-pc it did show this message:

  console: i2c i2c-0: mv64xxx: I2C bus locked, block: 1, time_left: 0
  console: sy8106a: probe of 0-0065 failed with error -110

The SY8106a appears to be an peripheral attached to the I2C bus on the orangepi-pc, and we don't emulate the SY8106a yet, so that's an error to be expected:

  https://linux-sunxi.org/SY8106A

So for the series:

I'll try to reply to each patch as well.

Kind regards,

Niek

This patch series adds missing Allwinner A10 modules needed for
successful SPL boot:
- Clock controller module
- DRAM controller
- I2C0 controller (added also for Allwinner H3 since it is the same)
- AXP-209 connected to I2C0 bus

It also updates Allwinner A10 emulation so SPL is copied from attached
SD card if `-kernel` parameter is not passed when starting QEMU
(approach adapted from Allwinner H3 implementation).

Boot from SD card has been tested with Cubieboard Armbian SD card image and custom
Yocto image built for Cubieboard.
Example usage for Armbian image:
qemu-system-arm -M cubieboard -nographic -sd ~/Armbian_22.11.0-trunk_Cubieboard_kinetic_edge_6.0.7.img
