No, sorry. Thanks for noticing. I'll resend with the change that Stefan
suggested and keep your Tested-by.

Equivalent code that disables the hidden i2c0 slave already exists in

affected. Add code to disable this slave to the i2c bus driver to make
it work on all affected hardware.
Use the bind callback because we want this to always run at boot,
regardless of whether U-Boot uses the i2c bus.

I'll submit a patch to add IS_ENABLED(CONFIG_KIRKWOOD) when this hits
u-boot.git.
Have you hit this issue on Kirkwood? Which one?
Custom board with Kirkwood 88F6281_A0
Before
=> i2c probe Valid chip addresses: 48 50 51 52 53 64 70 71 72 73 74
After
=> i2c probe Valid chip addresses: 48 50 51 52 53 70 71 72 73 74
May you and Siach can add this immediately in v2 ?
bye,
Heiko
