Subject: [PATCH v2 6/9] mmc: meson-gx: set max block count and request size
Date: Wed, 1 Feb 2017 07:49:07 +0100	[thread overview]
Message-ID: <aa425902-457d-2cd8-bc2a-4bac6938f076@gmail.com> (raw)
In-Reply-To: <584e5061-d359-1436-05ee-3767a5a4b10f@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.
