Subject: [PATCH v6 2/2] arm64: dts: qcom: sm8550: extend the register range for UFS ICE
Date: Fri, 06 Sep 2024 19:56:01 +0200 [thread overview]
Message-ID: <20240906-wrapped-keys-dts-v6-2-3f0287cf167e@linaro.org> (raw)
In-Reply-To: <20240906-wrapped-keys-dts-v6-0-3f0287cf167e@linaro.org>
From: Gaurav Kashyap <quic_gaurkash@quicinc.com>
The Inline Crypto Engine (ICE) for UFS/EMMC supports the Hardware Key
Manager (HWKM) to securely manage storage keys. Enable using this
hardware on sm8550.
This requires us to increase the register range: HWKM is an additional
piece of hardware sitting alongside ICE, and extends the old ICE's
register space.
NOTE: Although wrapped keys cannot be independently generated and
tested on this platform using generate, prepare and import key calls,
there are non-kernel paths to create wrapped keys, and still use the
kernel to program them into ICE. Hence, enabling wrapped key support
on sm8550 too.
