From ceeee8f7b5f10d7736840b169249e891da0f6a47 Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Fri, 10 Aug 2018 02:39:33 -0700 Subject: x86: coreboot: Add generic coreboot payload support Currently building U-Boot as the coreboot payload requires user to change the build configuration for a specific board during menuconfig process. This uses the board's native device tree to configure the hardware. For example, the device tree provides PCI address range for the PCI host controller and U-Boot will re-program all PCI devices' BAR to be within this range. In order to make sure we don't mess up the hardware, we should guarantee the range matches what coreboot programs the chipset. But we really should make the coreboot payload support easier. Just like EFI payload, we can create a generic coreboot payload for all x86 boards as well. The payload is configured to include as many generic drivers as possible. All stuff that touches low level initialization are not allowed as such is the coreboot's responsibility. Platform specific drivers (like gpio, spi, etc) are not included.
