From 0d3efd805618068f33ec8dd3610b1cd740afb5cd Mon Sep 17 00:00:00 2001 From: Chris Packham Date: Mon, 27 May 2013 10:51:46 +1200 Subject: powerpc/CoreNet: Allow pbl images to take u-boot images != 512K Instead of assuming that SYS_TEXT_BASE is 0xFFF80000 calculate the initial pbl command offset by subtracting the image size from the top of the 24-bit address range. Also increase the size of the memory buffer to accommodate a larger output image.
