arch/powerpc/*/config.mk: make CONFIG_SYS_LDSCRIPT settings work As we try to get rid of board specific config.mk files we must provide a way for board specific settings of the LDSCRIPT variable (path to the linker script) where needed. We now implement the following hierarchy: - Highest priority has a "#define CONFIG_SYS_LDCONFIG" in the board config file. - If CONFIG_SYS_LDCONFIG is not set, and the system is booting from NAND (CONFIG_NAND_SPL is set), then a board specific linker script board/$(BOARDDIR)/u-boot-nand.lds gets used. - If we are not booting from NAND, we test if a processor specific linker script arch/powerpc/cpu/$(CPU)/u-boot.lds exists; if so we use that. - As default, arch/powerpc/config.mk gets used.

kbuild: rename OBJTREE to objtree Prior to Kbuild, $(OBJTREE) was used for pointing to the top of build directory with absolute path. In Kbuild style, $(objtree) is used instead. This commit renames OBJTREE to objtree and delete the defition of OBJTREE. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>

kbuild: rename TOPDIR to stctree Prior to Kbuild, $(TOPDIR) or $(SRCTREE) was used for pointing to the top of source directory. (No difference between the two.) In Kbuild style, $(srctree) is used instead. This commit renames TOPDIR to srctree and delete the defition of TOPDIR. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>

ppc4xx: Clean up 440 exceptions handling - Introduced dedicated switches for building 440 and 405 images required for 440-specific machine instructions like 'rfmci' etc. - Exception vectors moved to the proper location (_start moved away from the critical exception handler space, which it occupied) - CriticalInput now serviced (with default handler) - MachineCheck properly serviced (added a dedicated handler and return subroutine) - Overall cleanup of exceptions declared with STD_EXCEPTION macro (unused, unhandled and those not relevant for 4xx were eliminated) - Eliminated Linux leftovers, removed dead code Signed-off-by: Grzegorz Bernacki <gjb@semihalf.com> Signed-off-by: Rafal Jaworowski <raj@semihalf.com> Signed-off-by: Stefan Roese <sr@denx.de>
