This commit adapts the files that were derived from PIBS (PowerPC Initialization and Boot Software) codeto using SPDX License Identifiers. So far, SPDX has not assigned an official License ID for the PIBS license yet, so this should be considered preliminary. Note that the following files contained incorrect license information: arch/powerpc/cpu/ppc4xx/4xx_uart.c arch/powerpc/cpu/ppc4xx/start.S arch/powerpc/include/asm/ppc440.h These files included, in addition to the GPL-2.0 / ibm-pibs dual license as inherited from PIBS, a GPL-2.0+ license header which was obviously incorrect. This has been removed. Signed-off-by: Wolfgang Denk <wd@denx.de> Cc: Stefan Roese <sr@denx.de> Signed-off-by: Wolfgang Denk <wd@denx.de> Conflicts: Licenses/README Acked-by: Stefan Roese <sr@denx.de>
