Subject: [PATCH v6 08/14] crypto: caam - make CAAM_PTR_SZ dynamic
Date: Wed, 17 Jul 2019 08:24:52 -0700	[thread overview]
Message-ID: <20190717152458.22337-9-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20190717152458.22337-1-andrew.smirnov@gmail.com>

In order to be able to configure CAAM pointer size at run-time, which
needed to support i.MX8MQ, which is 64-bit SoC with 32-bit pointer
size, convert CAAM_PTR_SZ to refer to a global variable of the same
name ("caam_ptr_sz") and adjust the rest of the code accordingly. No
functional change intended.
