Subject: [PATCH v5 4/4] nfit-test: Add platform cap support from ACPI 6.2a to test
Date: Wed, 31 Jan 2018 12:45:55 -0700	[thread overview]
Message-ID: <151742795542.53525.10921968294502970416.stgit@djiang5-desk3.ch.intel.com> (raw)
In-Reply-To: <151742786907.53525.180738048776121385.stgit@djiang5-desk3.ch.intel.com>

Adding NFIT platform capabilities sub table in nfit_test simulated ACPI
NFIT table. Only the first NFIT table is added with the capability
sub-table.
