From 14ed50a4bfadf7bc3437b325ec655c79bddd8833 Mon Sep 17 00:00:00 2001 From: Siva Durga Prasad Paladugu Date: Wed, 18 Jul 2018 16:31:38 +0530 Subject: [PATCH] arm64: zynqmp: Add QSPI flash mini u-boot configuration Add configuration files/dtses for mini u-boot configuration which runs on smaller footprint of internal memory. This configuration has only required qspi flash support and it uses DCC as serial.
