[new uImage] Rename architecture specific bootm code files
Implementation of the do_bootm_linux() and other bootm helper routines is architecture specific code. As such it resides in lib_<arch> directories in files named <arch>_linux.c This patch renames those files to a more clear and accurate lib_<arch>/bootm.c form. List of the renamed files: lib_arm/armlinux.c -> lib_arm/bootm.c lib_avr32/avr32_linux.c -> lib_avr32/bootm.c lib_blackfin/bf533_linux.c -> lib_blackfin/bootm.c lib_i386/i386_linux.c -> lib_i386/bootm.c lib_m68k/m68k_linux.c -> lib_m68k/bootm.c lib_microblaze/microblaze_linux.c -> lib_microblaze/bootm.c lib_mips/mips_linux.c -> lib_mips/bootm.c lib_nios/nios_linux.c -> lib_nios/bootm.c lib_nios2/nios_linux.c -> lib_nios2/bootm.c lib_ppc/ppc_linux.c -> lib_ppc/bootm.c lib_sh/sh_linux.c -> lib_sh/bootm.c Signed-off-by: Marian Balakowicz <m8@semihalf.com>
