Browse Source 
These 2 options are no longer needed as now binman is used to build
u-boot.rom.

Enable this if building the u-boot.rom target needs binary blobs, and
so cannot be done normally. In this case, U-Boot will only build the
ROM if the required blobs exist. If not, you will see an warning like:

This option allows to build a ROM version of U-Boot.
The build process generally requires several binary blobs
which are not shipped in the U-Boot source tree.

-------------------------------------------------------------
Building a ROM version of U-Boot (hereafter referred to as u-boot.rom) is a
little bit tricky, as generally it requires several binary blobs which are not
shipped in the U-Boot source tree. Due to this reason, the u-boot.rom build is
not turned on by default in the U-Boot source tree. Firstly, you need turn it
on by enabling the ROM build either via an environment variable::
$ export BUILD_ROM=y
or via configuration::
CONFIG_BUILD_ROM=y
Both tell the Makefile to build u-boot.rom as a target.
shipped in the U-Boot source tree. Due to this reason, the u-boot.rom build may
print some warnings if required binary blobs (e.g.: FSP) are not present.
