Kbuild: introduce Makefile in arch/$ARCH/

2014-12-08T14:35:45+00:00

Introduce a Makefile under arch/$ARCH/ and include it in the
top Makefile (similar to Linux kernel). This allows further
refactoringi like moving architecture-specific code out of global
makefiles, deprecating config variables (CPU, CPUDIR, SOC) or
deprecating arch/$ARCH/config.mk.

In contrary to Linux kernel, U-Boot defines the ARCH variable by
Kconfig, thus the arch Makefile can only included conditionally
after the top config.mk.

kconfig: add CONFIG_SUPPORT_SPL

2014-10-27T21:54:10+00:00

CONFIG_SPL should not be enabled for boards that do not have SPL.
CONFIG_SUPPORT_SPL introduced by this commit should be "select"ed
by boards with SPL support and CONFIG_SPL should depend on it.

kconfig: remove redundant "string" type in arch and board Kconfigs

2014-09-13T20:43:55+00:00

Now the types of CONFIG_SYS_{ARCH, CPU, SOC, VENDOR, BOARD, CONFIG_NAME}
are specified in arch/Kconfig.

We can delete the ones in arch and board Kconfig files.

This commit can be easily reproduced by the following command:

find . -name Kconfig -a ! -path ./arch/Kconfig | xargs sed -i -e '
/config[[:space:]]SYS_\(ARCH\|CPU\|SOC\|\VENDOR\|BOARD\|CONFIG_NAME\)/ {
    N
    s/\n[[:space:]]*string//
}
'

microblaze: Fix printf size_t format related warnings (again...)

2014-09-09T07:58:36+00:00

The basic idea: Define size_t using the __SIZE_TYPE__ compiler-defined
type.

For detailed explanation see similar patch for the nios2 arch:
"nios2: Fix printf size_t format related warnings (again...)"
(sha1: 00a2517fcb5159ed016b25130184638b1dbf2f02)

kconfig: add board Kconfig and defconfig files

2014-07-30T12:48:01+00:00

This commit adds:
 - arch/${ARCH}/Kconfig
    provide a menu to select target boards
 - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig
    set CONFIG macros to the appropriate values for each board
 - configs/${TARGET_BOARD}_defconfig
    default setting of each board

(This commit was automatically generated by a conversion script
based on boards.cfg)

In Linux Kernel, defconfig files are located under
arch/${ARCH}/configs/ directory.
It works in Linux Kernel since ARCH is always given from the
command line for cross compile.

But in U-Boot, ARCH is not given from the command line.
Which means we cannot know ARCH until the board configuration is done.
That is why all the "*_defconfig" files should be gathered into a
single directory ./configs/.

Makefile: Support include files for .dts files

2014-06-20T17:55:03+00:00

Linux supports this, and if we are to have compatible device tree files,
U-Boot should also.

Avoid giving the device tree files access to U-Boot's include/ directory.
Only include/dt-bindings is accessible.

fdt_support: delete force argument of fdt_initrd()

2014-06-19T15:18:47+00:00

After all, we have realized "force" argument is completely
useless. fdt_initrd() was always called with force = 1.

We should always want to do the same thing
(set appropriate value to the property)
even if the property already exists.

bd_info: remove bi_barudrate member from struct bd_info

2014-05-12T19:19:45+00:00

gd->bd->bi_baudrate is a copy of gd->baudrate.

Since baudrate is a common feature for all architectures,
keep gd->baudrate only.

It is true that bi_baudrate was passed to the kernel in that structure
but it was a long time ago.

kbuild: delete redundant LDSCRIPT definition

2014-03-12T21:04:46+00:00

$(SRCTREE)/$(CPUDIR)/u-boot.lds is our default location
of arch-specific linker script.

Remove redundant definitions in
arch/{arc,microblaze,openrisc}/config.mk.

kbuild: fix CROSS_COMPILE settings in config.mk

2014-03-04T17:15:30+00:00

The syntax
  CROSS_COMIPLE ?= 
does not work because config.mk is parsed after
exporting CROSS_COMPILE.

Like Linux Kernel's arch/$(ARCH)/Makefile,
we must write as follows:

  ifeq ($(CROSS_COMPILE),)
  CROSS_COMPILE := 
  endif
