Build packages for generic Arm architecture
The current aarch64 version of VPP package distro in cloud repository (https://packagecloud.io/fdio/master/ubuntu), is built on a ThunderX server, using some arch-specific options, for example, 128Byte cache line size, T=arm64-thunderx-linuxapp-gcc, RTE_MACHINE=thunderx The patch is trying to build package distro with aarch64 generic features, for both binary type targets, e.g., build/build-release, and package type targets, e.g., pkg-deb/pkg-rpm, with the generic options, e.g., 128Byte cache line size, T=arm64-armv8a-linuxapp-gcc, RTE_MACHINE=armv8a If end users want to build arch specific optimized image, TARGET_PLATFORM variable could be used, as below example, $ make build-release/pkg-deb TARGET_PLATFORM=thunderx Change-Id: If78bca8709fe83db6a95e8c26346f206bf5ea71d Signed-off-by: Lijian Zhang <Lijian.Zhang@arm.com> Reviewed-by: Sirshak Das <Sirshak.Das@arm.com> Reviewed-by: Honnappa Nagarahalli <Honnappa.Nagarahalli@arm.com>
