Subject: [PATCH v2 0/2] Enhance support for the AMD's fTPM
Date: Mon,  9 Sep 2019 18:09:04 +0900	[thread overview]
Message-ID: <20190909090906.28700-1-kkamagui@gmail.com> (raw)

This patch series enhances the support for the AMD's fTPM. 
The AMD system assigned a command buffer and response buffer 
independently in ACPI NVS region. ACPI NVS region allowed nothing to 
assign a resource in it. 

For supporting AMD's fTPM, I made a patch to enhance the code of command 
and response buffer size calculation. I also made a patch to detect TPM 
regions in ACPI NVS and work around it. 

Changes in v2:
 - fix a warning of kbuild test robot. The link is below.
