Re: [Buildroot] [PATCH v3 3/3] configs/freescale_imx93evk: new defconfig

[Julien Olivain <ju.o@free.fr>]

Hi Sébastien, All,

Thanks for the update!

I successfully built this freescale_imx93evk_defconfig
and booted on the NXP i.MX93 EVK board, with the patch
series applied on branch master at commit ef0fa98.
