[U-Boot] [PATCH 15/16] of: flip CONFIG_SPL_DISABLE_OF_CONTROL into CONFIG_SPL_OF_CONTROL

Masahiro Yamada yamada.masahiro at socionext.com
Sun Jul 26 10:26:59 CEST 2015


As we discussed a couple of times, negative CONFIG options make our
life difficult; CONFIG_SYS_NO_FLASH, CONFIG_SYS_DCACHE_OFF, ...
and here is another one.

Now, there are actually two boards enabling OF_CONTROL on SPL:
 - socfpga_arria5_defconfig
 - socfpga_cyclone5_defconfig

But they were enabled by mistake.

Commit 47a785a9dd97 ("dts: Disable device tree for SPL on all
boards") missed to add CONFIG_SPL_DISABLE_OF_CONTROL on those
two boards.  They were silently enabled with OF_CONTROL on SPL
without notifying their maintainers.

After all, there exist no boards to support it in a justified
process.

Before being too late, delete all the defines in defconfig files
and 'select's in Kconfig, and invert the logic.
