From e9acb9ea430e3638f1306993b10a10385092b20a Mon Sep 17 00:00:00 2001 From: Siva Durga Prasad Paladugu Date: Thu, 3 Dec 2015 15:46:03 +0100 Subject: [PATCH] common: board: Dont relocate FDT incase of CONFIG_OF_EMBED Don't relocate fdt in case of CONFIG_OF EMBED as the fdt is already embedded with u-boot image. Update fdt_blob after relocation as the fdt will be copied during u-boot relocation.
