Using QSPI for Boot
1. Create the QSPI boot image(s) for either or both single flashmode and dual parallel
mode.
Single Flash Mode
dd if=/dev/zero of=qemu_qspi.bin bs=64M count=1
dd if=BOOT.BIN of=qemu_qspi.bin bs=1 seek=0 conv=notrunc
Dual Parallel Mode
dd if=/dev/zero bs=128M count=1 of=qemu_qspi_tmp.bin
dd if=BOOT.BIN of=qemu_qspi_tmp.bin bs=1 seek=0 conv=notrunc
flash_strip_bw qemu_qspi_tmp.bin qemu_qspi_low.bin qemu_qspi_high.bin
2. Boot either the single or dual image(s) on QEMU.
