Subject: [Xen-devel] [PATCH v6 10/10] tools/arm: optee: create optee firmware node in DT if tee=optee
Date: Tue, 11 Jun 2019 18:46:49 +0000
Message-ID: <20190611184541.7281-11-volodymyr_babchuk@epam.com> (raw)
In-Reply-To: <20190611184541.7281-1-volodymyr_babchuk@epam.com>

If TEE support is enabled with "tee=optee" option in xl.cfg,
then we need to inform guest about available TEE, by creating
corresponding node in the guest's device tree.

 This patch depends on patches to optee.c.

 Changes from v4:
  - "native" option replaced with "optee"

 Changes from v3:
  - "smc" method replaced with "hvc"
  - Coding style fixes
