SubjectRe: [PATCH 2/2] arc: hsdk_defconfig: enable CONFIG_ARC_UBOOT_SUPPORT
Date
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.
