Subject: [PATCH 1/8] x86: Add a new X86_RUN_64BIT_ONLY to Kconfig
Date: Tue, 21 Apr 2020 17:45:00 -0700 [thread overview]
Message-ID: <20200422004507.2025-2-aiden.park@intel.com> (raw)
In-Reply-To: <20200422004507.2025-1-aiden.park@intel.com>
From: Aiden Park <aiden.park@intel.com>
This will build U-Boot as a pure 64-bit binary with no SPL.
It can be used with a pre-stage boot firmware
which has already done 16-bit, 32-bit and 64-bit init.
