Subject: [PATCH v2] mmc: meson-gx: set max block count
Date: Sat, 28 Jan 2017 09:25:35 +0100	[thread overview]
Message-ID: <0309625d-e24b-13e1-bba7-ada6b5a202c1@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).

Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com>
---
v2:
- 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
