[Gary Bisson <gary.bisson@boundarydevices.com>]

Hi Stephane,

Sorry for the late reply, apart for the comments already made by otherse
I have one suggestion below.

So here you would copy all VPU FW for "LEGACY" but the one for
IMX8/IMX8X?
I'd rather have a generic IMX_NEED_VPU_FW for all platforms that require
a VPU FW and then in firmware-imx.mk only copy the files relevant to the
platform selected (imx35,51,6,8x), what do you think?
