LDR format files are used primarily by Analog Devices processors but may be of interest to other vendors. Previously support existed for this format as part of the U-Boot build, but it has been unmaintained and unused for a long time. In preparation for adding support for modern ADI processors that use LDR, modernize the LDR support: - Introduce CONFIG_LDR_CPU as the CPU string recognized by the LDR tool may not be the same as CONFIG_CPU - Add an SPL target that repackages u-boot-spl inside an LDR file An almost identical target for packaging u-boot into an LDR file already exists and did not need to be created.

With configs such as "am64x_evm_a53" or "imx8mp_venice" which list multiple device trees to build we get a warning such as: scripts/Makefile.spl:578: target 'spl/dts/freescale/' given more than once in the same rule If we sort this list first the warning goes away.

Some boards that choose to utilize the OF_UPSTREAM directory for their device tree files will need to specify that directory instead of the traditional arch/$(ARCH)/dts/* path. Include the correct path to the board's dtbs depending on if OF_UPSTREAM is selected or not.

With sandbox, CONFIG_SANDBOX is y so the current rule ends up building
the devicetree for only those SPL builds where it is unwanted.
Correct the condition. This allows sandbox_vpl to produce a
u-boot-vpl.dtb file.

It is entirely possible at this point to have platforms in U-Boot that do not have board-specific C code (just Kconfig or environment) and so make it optional to have to descend in to and then build in the board directory. Signed-off-by: Tom Rini <trini@konsulko.com>

LTO (Link-Time Optimisation) is an very useful feature which can significantly reduce the size of U-Boot binaries. So far it has been made available for selected ARM boards and sandbox. However, incremental builds are much slower when LTO is used. For example, an incremental build of sandbox takes 2.1 seconds on my machine, but 6.7 seconds with LTO enabled. Add a NO_LTO parameter to the build, similar to NO_SDL, so it can be disabled during development if needed, for faster builds. Add some documentation about LTO while we are here.

This makes use of makefile variables that don't exist anymore. Fix it and
also remove the object files in that directory.
Also add FORCE as a dependency as required by the if_changed macro.

- In a number of cases, use CONFIG_ARCH_EXYNOS[45] rather than CONFIG_EXYNOS[45] - In other cases, test for CONFIG_ARCH_EXYNOS or CONFIG_ARCH_S5PC1XX - Migrate specific SoC CONFIG values to Kconfig - Use CONFIG_TARGET_x rather than CONFIG_x - Migrate other CONFIG_EXYNOS_x symbols to Kconfig - Reference CONFIG_EXYNOS_RELOCATE_CODE_BASE directly as EXYNOS_RELOCATE_CODE_BASE - Rename CONFIG_S5P_PA_SYSRAM to CONFIG_SMP_PEN_ADDR to match the rest of U-Boot usage.
