From 882ae41274921f9016131806bdeb27e19606f47a Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Mon, 22 Oct 2007 15:44:39 +0200 Subject: ppc4xx: Rework of 4xx serial driver (2) Change all linker scripts to reference the changed driver name 4xx_uart.o. Note: In most cased all these explicit referencing of these object files in the linker scripts is not neccessary. Only for manually embedded environment into the U-Boot image, which is not done is most cases.

On some boards however, changes to the code size (due to different optimizations) we bail out with section overlaps like above. The fix is to add the NOLOAD attribute to the .bss and .sbss sections, telling the linker that .bss does not consume any space in the image.
