kbuild,tegra124: add dummy obj- for Kbuild

2014-02-19T20:43:46+00:00

In Kbuild, every makefile must have non-empty obj- or obj-y.
Otherwise, built-in.o will not be created and the link stage
will fail.

Move CONFIG_DISPLAY_CPUINFO to Makefile

2014-02-19T16:10:05+00:00

If the whole code is surrounded by #ifdef(CONFIG_ ) .. #endif,
it should be moved to Makefile.

Move #ifdef(CONFIG_DISPLAY_CPUINFO) from caller to callee

2014-02-19T16:10:05+00:00

- When CONFIG_DISPLAY_CPUINFO is not enabled,
   print_cpuinfo() should be defined as an empty function
   in a header, include/common.h

 - Remove #ifdef CONFIG_DISPLAY_CPUINFO .. #endif
   from caller, common/board_f.c and arch/arm/lib/board.c

 - Remove redundant prototypes in arch/arm/lib/board.c,
   arch/arm/include/asm/arch-am33x/sys_proto.h and
   board/nokia/rx51/rx51.h, keeping the one in include/common.h

 - Add #ifdef CONFIG_DISPLAY_CPUINFO to the func definition
   where it is missing

configs: Delete obsolete macro, CONFIG_SYS_GBL_DATA_SIZE

2014-02-19T16:10:05+00:00

CONFIG_SYS_GBL_DATA_SIZE is not used any more.
The size of struct "global_data" is automatically calculated
by asm-offsets. (See lib/asm-offsets.c)

GENERATED_GBL_DATA_SIZE should be used instead of
CONFIG_SYS_GBL_DATA_SIZE.

dts: generate multiple device tree blobs

2014-02-19T16:10:05+00:00

It is convenient to have all device trees on the same SoC compiled.
It allows for later easy repackaging without the need to re-run
the make file.

  - Build device trees with the same SoC under arch/$(ARCH)/dts

  - Copy the one specified by CONFIG_DEFAULT_DEVICE_TREE or
    DEVICE_TREE=... to dts/dt.dtb

dts: move device tree sources to arch/$(ARCH)/dts/

2014-02-19T16:10:05+00:00

Unlike Linux Kernel, U-Boot historically had *.dts files under
board/$(VENDOR)/dts/ and *.dtsi files under arch/$(ARCH)/dts/.

I think arch/$(ARCH)/dts dicretory is a better location
to store both *.dts and *.dtsi files.

For example, before this commit, board/xilinx/dts directory
had both Microblaze dts (microblaze-generic.dts) and
ARM dts (zynq-*.dts), which are totally unrelated.

This commit moves *.dts to arch/$(ARCH)/dts/ directories,
allowing us to describe nicely mutiple DTBs generation in the next commit.

dts: re-write dts/Makefile more simply with Kbuild

2014-02-19T16:10:05+00:00

Useful rules in scripts/Makefile.lib allows us to easily
generate a device tree blob and wrap it in assembly code.

We do not need to parse a linker script to get output format and arch.

This commit deletes ./u-boot.dtb since it is a copy of dts/dt.dtb.
