From 90a6695a2ac1b9db8e0f4bfec3156c22a722d9ba Mon Sep 17 00:00:00 2001 From: Michal Simek Date: Wed, 14 May 2014 16:46:00 +0200 Subject: [PATCH] ARM: zynq: Fix uart0 early console virtual address Virtual address have to have the same offset within a 2MB aligned section of virtual/phycial address space. Fix uart0 virtual address to be align with physical one. Also remove UART_SIZE which is completely unused.
