Subject: [PATCH] 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.
