x86: Change how selection of ROMs works
Most x86 boards build a u-boot.rom which is programmed into SPI flash. But this is not unique to x86. For example some rockchip boards can also boot from SPI flash. Also, at least on x86, binary blobs are sadly quite common. It is not possible to build a functional image without them, and U-Boot needs to know this at build time. Introduce a new CONFIG_HAS_ROM option which selects whether u-boot.rom is built and a new CONFIG_ROM_NEEDS_BLOBS option to indicate whether binary blobs are also needed. If they are not needed, it is safe to build the ROM always. Otherwise we still require the BUILD_ROM environment variable. For now this affects only x86, but future patches will enable this for rockchip too. Signed-off-by: Simon Glass <sjg@chromium.org>
