Subject: [PATCH 6/9] mmc: meson-gx: set max block count and request size
Date: Tue, 31 Jan 2017 21:58:40 +0100 [thread overview]
Message-ID: <092dee0d-1115-7f0f-90da-60b92e0bf5c3@gmail.com> (raw)
In-Reply-To: <24e8bf35-50ce-270d-c0aa-12bb90d2e3d8@gmail.com>
So far max_blk_count isn't set what results in a default of value 8
to be used (PAGE_SIZE / block size).
Block length field has 9 bits, so set max_blk_count to 2^9-1 = 511.
In addition set max_req_size because max_blk_count is also limited
by max_req_size / block_size.
