From dd39bcaffbc886e5948d5b6dc0a4156a8b0ba053 Mon Sep 17 00:00:00 2001 From: Sjoerd Simons Date: Sun, 30 Aug 2015 16:55:50 -0600 Subject: rockchip: Drop first 32kb of zeros from the rkSD image type Instead of creating a rockchip SPL SD card image with 32KB of zeros which can be written to the start of an SD card, create the images with only the useful data that should be written to an offset of 32KB on the SD card. The first 32 kilobytes aren't needed for bootup and only serve as convenient way of accidentally obliterating your partition table.
