-Top level ARC makefile removes -I for platform headers -asm/irq.h no longer includes plat/irq.h -platform makefile adds -I for it's specfic platform headers -platform code to directly include it's plat/irq.h -Linker script needed plat/memmap.h for CCM info, already in .config Signed-off-by: Vineet Gupta <vgupta@synopsys.com> Cc: Arnd Bergmann <arnd@arndb.de> Acked-by: Arnd Bergmann <arnd@arndb.de>
