-----Original Message----- From: Sudeep Holla [mailto:sudeep.holla@arm.com] Sent: 25 August 2016 18:09 To: edk2-devel@lists.01.org; Linaro UEFI; Evan Lloyd; Leif Lindholm Cc: Sudeep Holla; ard.biesheuvel@linaro.org Subject: [PATCH] Platforms/ARM/Juno: limit ACPI support to v5.0 and higher
The ACPI spec predates the AARCH64 architecture by 5 versions, so there is no point in supporting anything below v5.0. So set the PCD that controls the ACPI table generation to the appropriate value.
Based on the commit e0692789058e ("ArmVirtPkg/ArmVirtQemu: limit ACPI support to v5.0 and higher") in the upstream TianoCore by Ard Biesheuvel
