From efe0b669716314072f0467368c2be2f501f04afc Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Tue, 7 Feb 2017 22:34:58 +0100 Subject: [PATCH] mmc: meson-gx: set max block count and request size 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.
