:<code>bora_qspi</code> and <code>borax_qspi</code>: U-Boot is built to use NOR flashed based environment. The resulting binary files are used to boot from serial NOR flash.:<code>bora_mmc</code> and <code>borax_mmc</code>: U-Boot environment is placed in SD/MMC card. The resulting binary files are used to boot from SD/MMC card. However, NOR flash and NAND flash are accessible.:<code>bora_noflash</code> and <code>borax_noflash</code>: U-Boot environment is placed in SD/MMC card. The resulting binary files are used to boot from SD/MMC card. NOR flash and NAND flash are disabled.
* build U-Boot by issuing <code>make</code> command. This will generate U-Boot binary images.
