+Zedboard First-Stage Bootloader (FSBL)
+===========
+
+Simple FSBL for the Zedboard. It is currently only capable of QSPI boot. It searches for a
+bitstream and ELF file inside the boot binary, flashes them and jumps to the ELF file.
+
+It can be easily adapted to other boards by changing the static DDR/DDRIOB configuration
+and the used QSPI memory driver.

+Zedboard QSPI flasher
+============
+
+This application flashes a boot binary generated by the AMD `bootgen` utility from DDR
+to the Zedboard QSPI. This project contains a `qspi-flasher.tcl` script which can be invoked
+with `xsct` to flash a `boot.bin` and the QSPI flasher to DDR adn then run the application.
