__init_end, which comes immediately before .text, is already page aligned, and that should be more than enough for the .text section. The reason why we need to align the .text section is because the interrupt handler offset is ORed with EVBA, so we need to provide enough alignment of EVBA that this OR operation works as an ADD. Currently, the last interrupt handler is not nearly a full page away from EVBA, so it won't be a problem. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
