Changelog v9 -> v10 * Update commit message to include the changelog before the SoB tag(s). v8 -> v9 * No changes. v7 -> v8 * No changes. v6 -> v7 * Remove, for now, the dependency on ARM64 arch. x86 is currently supported, with Arm to come afterwards. The NE kernel driver can be built for aarch64 arch. v5 -> v6 * No changes. v4 -> v5 * Add arch dependency for Arm / x86. v3 -> v4 * Add PCI and SMP dependencies. v2 -> v3 * Remove the GPL additional wording as SPDX-License-Identifier is already in place. v1 -> v2 * Update path to Kconfig to match the drivers/virt/nitro_enclaves directory. * Update help in Kconfig.
