U-Boot boot command: tftpboot 0x48080000 Image tftpboot 0x48f00000 r8a7795-salvator-x.dtb (for R-Car H3) tftpboot 0x48f00000 r8a7796-salvator-x.dtb (for R-Car M3-W) booti 0x48080000 - 0x48f00000

Test procedures

 * Tests:eMMC-8bit-width: Test the on-board eMMC with an 8 bit bus width
 * Tests:SCIF-FIFO: Test SCIF FIFO behavior, using SCIF3 and HSCIF3 on expansion I/O connectors
 * Tests:SDIO-KS7010: Test SDIO with a Spectec SDW823 microSD card (using an SD size adapter) on connectors CN13 or CN14
 * Tests:SDIO-H3-Voltage-Switching: Test if voltages change properly when inserting UHS capable SD cards into connectors CN13 or CN14
 * Tests:Watchdog-Pretimeout: Test watchdog pretimeouts. Because the hardware watchdog (RWDT) doesn't support this feature, a software watchdog must be used in addition
