From e025e17b3341cd20cebe721ce2d70d2d69d2d5ce Mon Sep 17 00:00:00 2001 From: Shawn Nematbakhsh Date: Thu, 12 Jan 2017 11:16:06 -0800 Subject: system: Use stored size in image_data for determining image_used Image used size is now part of the image_data struct present in all images at a fixed offset, so use it rather than scanning from the end of the image. BUG=chromium:577915 TEST=Verify on kevin + lars + lars_pd that system_get_image_used() returns the same value as the old implementation, for both RO and RW images.
