Subject: [PATCH 3/7] OvmfPkg/PlatformPei: use QemuFwCfgParseBool in UPDATE_BOOLEAN_PCD_FROM_...
Date: Fri, 24 Apr 2020 09:53:49 +0200 [thread overview]
Message-ID: <20200424075353.8489-4-lersek@redhat.com> (raw)
In-Reply-To: <20200424075353.8489-1-lersek@redhat.com>
The UPDATE_BOOLEAN_PCD_FROM_FW_CFG() macro currently calls the
module-private helper function GetNamedFwCfgBoolean(). Replace the latter
with QemuFwCfgParseBool() from QemuFwCfgSimpleParserLib.
This change is compatible with valid strings accepted previously.
