6825a95b0b kbuild: use Linux Kernel build scripts
Now we are ready to switch over to real Kbuild.

This commit disables temporary scripts:
  scripts/{Makefile.build.tmp, Makefile.host.tmp}
and enables real Kbuild scripts:
  scripts/{Makefile.build,Makefile.host,Makefile.lib}.

This switch is triggered by the line in scripts/Kbuild.include
  -build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj
  +build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj

We need to adjust some build scripts for U-Boot.
But smaller amount of modification is preferable.

Additionally, we need to fix compiler flags which are
locally added or removed.

In Kbuild, it is not allowed to change CFLAGS locally.
Instead, ccflags-y, asflags-y, cppflags-y,
CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o
are prepared for that purpose.

643aae1406 include: delete include/linux/config.h
Linux Kernel abolished include/linux/config.h long time ago.
(around version v2.6.18..v2.6.19)

We don't need to provide Linux copatibility any more.

This commit deletes include/linux/config.h
and fixes source files not to include this.

2cb0e55a3c avr32/m68k/microblaze/nds32/nios2/openrisc/sh/sparc: fix do_bootm_linux
Commit 35fc84fa1f broke bootm on avr32. It
requires to call do_bootm_linux() with flag set to BOOTM_STATE_OS_PREP before
calling it again with flag set to BOOTM_STATE_OS_GO.
Fix this by allowing flag set to BOOTM_STATE_OS_PREP, this however will
require a complete refactoring later on.

1865286466 Introduce generic link section.h symbol files
We create a separate header file for link symbols defined by the link
scripts. It is helpful to have these all in one place and try to
make them common across architectures. Since Linux already has a similar
file, we bring this in even though many of the symbols there are not
relevant to us.

Each architecture has its own asm/sections.h where symbols specifc to
that architecture can be added. For now everything except AVR32 just
includes the generic header.

One change is needed in arch/avr32/lib/board.c to make this conversion
work.

3929fb0a14 Replace __bss_end__ with __bss_end
Note this is a tree-wide change affecting multiple architectures.

At present we use __bss_start, but mostly __bss_end__. This seems
inconsistent and in a number of places __bss_end is used instead.

Change to use __bss_end for the BSS end symbol throughout U-Boot. This
makes it possible to use the asm-generic/sections.h file on all
archs.

6c7c946cad common: Convert the U-Boot commands to LG-arrays
This patch converts the old method of creating a list of command
onto the new LG-arrays code. The old u_boot_cmd section is converted
to new u_boot_list_cmd subsection and LG-array macros used as needed.

Minor adjustments had to be made to the common code to work with the
LG-array macros, mostly the fixup_cmdtable() calls are now passed the
ll_entry_start and ll_entry_count instead of linker-generated symbols.

The command.c had to be adjusted as well so it would use the newly
introduced LG-array API instead of directly using linker-generated
symbols.
