Could you give some details on the use case for having a target package
for the imx_usb_loader ? Are you building a system with Buildroot that
itself is responsible for loading a bootloader over USB to a separate
i.MX6 target ? If not, what is your use case ?

Why do you have this dependency ? If your use case is as explained
above to build a Buildroot system that itself will be responsible for
loading over USB the bootloader of a separate i.MX6 device, then this
system may be running on something else than an ARM platform.

Indentation is wrong for this line, it should be indented with one tab.
I can fix this up when applying once the use case is clearer.

Best regards,

Hi Thomas,

For automatic testing purpose, I use an intermediate target (arm) between
host and DUT.
It uses imx_usb_loader and otp_com (https://github.com/ixonos/utp_com) as
described here:
https://community.nxp.com/thread/441563 to flash imx6 DUT with labgrid.

Indeed, extra arm depends is a mistake.

Sorry for indentation,

Best regards,
Vincent

I've applied to next, after doing the following changes:

    [Thomas:
     - improve commit log
     - fix indentation
     - drop BR2_arm dependency
     - add missing host-pkgconf dependency
     - fix prefix variable to install in $(TARGET_DIR)/usr]

Thanks!

Thomas
