Subject: [PATCH v3] mmc: meson-gx: set max block count
Date: Mon, 30 Jan 2017 20:33:47 +0100	[thread overview]
Message-ID: <b199dad5-e171-9c4a-2a44-83e0fe2365a9@gmail.com> (raw)

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.
