From 8e4ab1d58265884bbc9da6c6720d7a635f00fb2b Mon Sep 17 00:00:00 2001 From: Akshay Saraswat Date: Wed, 18 Jun 2014 17:53:58 +0530 Subject: Exynos5420: Introduce support for the Peach-Pit board While the Exynos5420 chip is used in both Smdk5420 and in the Peach-Pit line of devices, there could be other boards using the same chip, so a common configuration file is being added (exynos5420.h) as well as two common device tree files (exynos54xx.dtsi & exynos5420.dtsi). The peach board as declared in boards.cfg is a copy of smdk5420 declaration. The configuration files are similar, but define different default device trees, console serial ports and prompts. The device tree files for smdk5420 and peach-pit inherit from the same common file.
