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 three boards enabling OF_CONTROL on SPL: - socfpga_arria5_defconfig - socfpga_cyclone5_defconfig - socfpga_socrates_defconfig This commit adds CONFIG_SPL_OF_CONTROL for them and deletes CONFIG_SPL_DISABLE_OF_CONTROL from the other boards to invert the logic.

Some boards use device tree in U-Boot but only have 4KB of SRAM

which is not enough to support device tree. Enable this option to

|
Since SPL normally runs in a reduced memory space, the device tree
|
|
is cut down to only what is needed to load and start U-Boot. Only
|
|
nodes marked with the property "u-boot,dm-pre-reloc" will be
|
|
included. In addition, some properties are not used by U-Boot and
|
|
can be discarded. This option defines the list of properties to
|
|
discard.
