From d52e8575d9a4244992cd69e717affc97ea6e9b36 Mon Sep 17 00:00:00 2001 From: Karl Apsite Date: Thu, 21 May 2015 09:52:49 -0400 Subject: [PATCH] Combine bootm_find_ functions together bootm_find_ramdisk_fdt() renamed to bootm_find_images() for readability. The function bootm_find_ramdisk_fdt() appears to be a simple wrapper for bootm_find_ramdisk(), bootm_find_fdt(), and now bootm_find_loadables(). I didn't see any other callers entering a bootm_find, so removing the wrapper, and condensing these together hopefully makes the code a little simpler.
