From 6d2061b981af165d3e45462e0804b5a1f2f4c7bc Mon Sep 17 00:00:00 2001 From: Anup Patel Date: Tue, 1 Aug 2017 16:05:52 +0530 Subject: mailbox: bcm-flexrm-mailbox: Fix mask used in CMPL_START_ADDR_VALUE() The mask used in CMPL_START_ADDR_VALUE() should be 27bits instead of 26bits. This incorrect mask was causing completion writes to 40bits physical address fail. This patch fixes mask used in CMPL_START_ADDR_VALUE() macro.
