/*
 * A target board needs to set these variables for the commands below to work:
 *
 * - adi_stage2_offset, the location of stage2-boot.ldr on the SPI flash
 * - adi_image_offset, location of the fitImage on the SPI flash
 * - adi_rfs_offset, location of the RFS on the SPI flash
 * - loadaddr, where you want to load things
 * - jffs2file, name of the jffs2 file for update, ex adsp-sc5xx-tiny-adsp-sc573.jffs2
