Re: [PATCH v3 00/15] Add support to STMicroelectronics STM32 family

[Chanwoo Choi]

Hi Maxime,

I tested this patch-set on Linux 4.0-rc4 for STM32F429IDISCOVERY board.
I completed the kernel booting successfully without any modification .

Looks good to me for this patch-set.

Tested-by: Chanwoo Choi <cw00.choi@xxxxxxxxxxx>

Best Regards,
Chanwoo Choi
