Subject: [PATCH 4/4] efi: libstub/tpm: enable tpm eventlog function for ARM platforms
Date: Thu, 7 Nov 2019 16:10:36 +0100 [thread overview]
Message-ID: <20191107151036.5586-5-ardb@kernel.org> (raw)
In-Reply-To: <20191107151036.5586-1-ardb@kernel.org>
From: Xinwei Kong <kong.kongxinwei@hisilicon.com>
Wire up the existing code for ARM that loads the TPM event log into
OS accessible buffers while running the EFI stub so that the kernel
proper can access it at runtime.
