Hi Corentin, In case of devboards (like HSDK) we really often disable bootloader and load Linux image in memory via JTAG. Enabling CONFIG_ARC_UBOOT_SUPPORT by default will break it as we will try to interpret some junk in a registers as a pointers to bootargs/etc which aren't set by anyone in case of JTAG using.
So it isn't a good idea to have CONFIG_ARC_UBOOT_SUPPORT enabled by default.
