Subject: generic_board: do not set gd->fdt_blob unless CONFIG_OF_CONTROL=y
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=c970dffedb9f7bf76d67157c8ceba64496b0c64a;p=u-boot.git

generic_board: do not set gd->fdt_blob unless CONFIG_OF_CONTROL=y

gd->fdt_blob is used for FDT control of U-Boot.
If CONFIG_OF_CONTROL is not defined, it is useless.
