code (This goes hand in hand, as some parts of serial were hardcoded to one architecture until now) * include/uart8250.h: add TTYSx defines that are used in multiple places. formerly part of arch/x86/serial.c. Drop init_uart8250 (unused) * lib/uart8250.c: drop arch/x86/config.h usage Drop init_uart8250 (unused) * arch/powerpc/Kconfig, arch/x86/Kconfig: add CONFIG_ARCH to contain the directory name under LinuxBIOSv3/arch/ * arch/x86/console.c: drop some dead code. Drop hardcoded config.h values. use generic uart8250.h header * arch/x86/cachemain.c: Drop hardcoded config.h values. Still use hardcoded ROM size for now. (To be changed later) * arch/x86/config.h: dropped, no longer needed * arch/x86/serial.c: factor out generically used defines to uart8250.h * Makefile: use mainboard architecture instead of target architecture to choose include path. Read .xcompile if available (configure replacement). Create build.h with compile time and version. * util/xcompile/xcompile: new file. Search for supported cross compilers linkers, assemblers (and potentially supported compiler flags etc) This is a very slick configure replacement. * util/dtc/Makefile: fix Makefile for cross compilation Signed-off-by: Stefan Reinauer <stepan@coresystems.de> Signed-off-by: Uwe Hermann <uwe@hermann-uwe.de> Acked-by: Ronald G.
