[U-Boot] [PATCH v2 22/28] x86: baytrail: Add platform ASL files

Bin Meng bmeng.cn at gmail.com
Sat May 7 16:46:31 CEST 2016


This adds basic BayTrail platform ASL files. They are intended to be
included in dsdt.asl of any board that is based on this platform.

Note: ACPI mode support for GPIO/LPSS/SCC/LPE are not supported for
now. They will be added in the future.

Signed-off-by: Bin Meng <bmeng.cn at gmail.com>

---

Changes in v2:
- Reserve IRQ3 and IRQ4 in the IRQ links to support external SuperIO
  chipset serial ports
- Fix SIO1 and SIO2 interrupt mapping in irqroute.h
