Subject: rockchip: Enable building a SPI ROM image on jerry
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=9b312e26fc772965e6b48c2b452c08d42a9e288f;p=u-boot.git

rockchip: Enable building a SPI ROM image on jerry

Add a simple binman config and enable CONFIG_HAS_ROM so that U-Boot
produces a ROM for jerry.

Change the binman image definition to support multiple images, since it
may be used to build both u-boot-rockchip.bin and u-boot.rom
