[U-Boot] [PATCH v2 09/10] kconfig: move CONFIG_OF_* to Kconfig

Masahiro Yamada yamada.m at jp.panasonic.com
Tue Sep 16 09:33:06 CEST 2014 

This commit moves:
  CONFIG_OF_CONTROL
  CONFIG_OF_SEPARATE
  CONFIG_OF_EMBED
  CONFIG_OF_HOSTFILE

Because these options are currently not supported for SPL,
the "Device Tree Control" menu does not appear in the SPL
configuration.

Note:
zynq-common.h should be adjusted so as not to change the
default value of CONFIG_SPL_FAT_LOAD_PAYLOAD_NAME.

Note2:
CONFIG_OF_CONTROL should be 'select'ed for Tegra and Exynos 5
boards because the developers mentioned they always need DTB
to boot U-Boot.

Changes in v2:
  - Add "select OF_CONTROL" to TEGRA and Exynos5 boards
    because they always need a device tree to boot U-Boot
  - Add HAVE_OF_CONTROL_SUPPORT
  - Do not touch mx6qsabreauto board
    (This will be coverd by commit 19a895cbe9430 in u-boot-imx.
     Fabio has already sent a pull-req.)
  - cleanup left-over comments in include/configs/exynos-*.h
