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.

powerpc: ppc4xx: canyonlands: config: Tidy up CONFIGs and config.mk Many CONFIG options have an unnecessary value of 1. CONFIG_440 is set in the various board config files. Also simplify the CONFIG_440 check in config.mk Signed-off-by: Simon Glass <sjg@chromium.org> 2015-02-07 18:51:36 +00:00			`ifneq (,$(CONFIG_440))`
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> 2007-06-15 09:19:28 +00:00			`PLATFORM_CPPFLAGS += -Wa,-m440 -mcpu=440`
