From fb05f0b02b01aed48db48f02a15e52c6de2d0dac Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Sun, 3 Jun 2018 19:04:17 -0700 Subject: x86: cougarcanyon2: Remove CONFIG_HAVE_INTEL_ME As README.x86 already mentions, there are two SPI flashes mounted on Intel Cougar Canyon 2 board, called SPI-0 and SPI-1 respectively. SPI-0 stores the flash descriptor and the ME firmware. SPI-1 stores the actual BIOS image which is U-Boot. Building a single image with both ME firmware and U-Boot does not make sense. This also describes the exact flash location where the u-boot.rom should be programmed in the documentation.
