[U-Boot] [PATCH v2 0/2] config.mk: Delete unnecessary code

[Masahiro Yamada]

These consecutive patches delete the following code
in the top-level config.mk


ifneq ($(CONFIG_SPL_TEXT_BASE),)
CPPFLAGS += -DCONFIG_SPL_TEXT_BASE=$(CONFIG_SPL_TEXT_BASE)
endif

ifneq ($(CONFIG_SPL_PAD_TO),)
CPPFLAGS += -DCONFIG_SPL_PAD_TO=$(CONFIG_SPL_PAD_TO)
endif

ifneq ($(CONFIG_TPL_PAD_TO),)
CPPFLAGS += -DCONFIG_TPL_PAD_TO=$(CONFIG_TPL_PAD_TO)
endif

ifneq ($(CONFIG_UBOOT_PAD_TO),)
CPPFLAGS += -DCONFIG_UBOOT_PAD_TO=$(CONFIG_UBOOT_PAD_TO)
endif

ifneq ($(RESET_VECTOR_ADDRESS),)
CPPFLAGS += -DRESET_VECTOR_ADDRESS=$(RESET_VECTOR_ADDRESS)
endif


As for CONFIG_SPL_TEXT_BASE, CONFIG_UBOOT_PAD_TO,
CONFIG_RESET_VECTOR_ADDRESS, CONFIG_TPL_PAD_TO,
they are not defined in makefiles but only in config headers.
So, we can simply delete them. (This is done in 0001.)

As for CONFIG_SPL_PAD_TO, there is only one board which defines it in a makefile.
For refactoring, 0002 patch moves the definition of CONFIG_SPL_PAD_TO
from board/ait/cam_enc_4xx/config.mk to include/configs/cam_enc_4xx.h.
I added Cc Heiko Schocher, the maintainer of cam_enc_4xx board.

Heiko, a review is welcome if the refactoring in 0002 is acceptable or not.
If it is not acceptable, please apply only 0001 patch.

Note:
We have one more left in config.mk

ifneq ($(CONFIG_SYS_TEXT_BASE),)
CPPFLAGS += -DCONFIG_SYS_TEXT_BASE=$(CONFIG_SYS_TEXT_BASE)
endif

But too many boards still define CONFIG_SYS_TEXT_BASE in makefiles.
So I could not touch for now.
I think board maintainers should make effort to move
the CONFIG definition from config.mk to headers.
