+Summary
+=======
+The README is for the boot procedure on the ipam390 board
+
+In the context of U-Boot, the board is booted in three stages. The initial
+bootloader which executes upon reset is the ROM Boot Loader (RBL) and sits
+in the internal ROM. The RBL initializes the internal memory and then
+depending on the exact board and pin configurations will initialize another
+controller (such as NAND) to continue the boot process by loading
+the secondary program loader (SPL). The SPL will initialize the system
+further (some clocks, SDRAM). As on this board is used the falcon boot
+mode, now 2 ways are possible depending on the GPIO 7_14 input pin,
+connected with the "soft reset switch"
+
+If this pin is logical 1 (high level):
+spl code starts the kernel image without delay
+
+If this pin is logical 0 (low level):
+spl code starts the u-boot image
+
+AIS is an image format defined by TI for the images that are to be loaded
+to memory by the RBL. The image is divided into a series of sections and
+the image's entry point is specified. Each section comes with meta data
+like the target address the section is to be copied to and the size of the
+section, which is used by the RBL to load the image. At the end of the
+image the RBL jumps to the image entry point.  The AIS format allows for
+other things such as programming the clocks and SDRAM if the header is
+programmed for it.  We do not take advantage of this and instead use SPL as
+it allows for additional flexibility (run-time detect of board revision,
+loading the next image from a different media, etc).
+
+Compilation
+===========
+run "./MAKEALL ipam390" in the u-boot source tree.
+Once this build completes you will have a u-boot.ais file that needs to
+be written to the nand flash.
+
+Flashing the images to NAND
+==========================
+The AIS image can be written to NAND flash using the following commands.
+Assuming that the network is configured and enabled and the u-boot.ais file
+is tftp'able.
+
+U-Boot > print upd_uboot
+upd_uboot=tftp c0000000 ${u-boot};nand erase.part u-boot;nand write c0000000 20000 ${filesize}

+Recovery
+========
+
+In the case of a "bricked" board, you need to use the TI tools found
+here[1] to create an uboot-uart-ais.bin file
+
+- cd to the u-boot source tree
+
+- compile the u-boot for the ipam390 board:
+$ ./MAKEALL ipam390
+
+  -> Now we shall have u-boot.bin
+
+- Create u-boot-uart-ais.bin
+$ mono HexAIS_OMAP-L138.exe -entrypoint 0xC1080000 -ini
+ipam390-ais-uart.cfg -o ./uboot-uart-ais.bin ./u-boot.bin@0xC1080000;
+
+Note: The ipam390-ais-uart.cfg is found in the board directory
+for the ipam390 board, u-boot:/board/Barix/ipam390/ipam390-ais-uart.cfg
+
+- We can now run bootloader on IPAM390 via UART using the command below:
+
+$ mono ./slh_OMAP-L138.exe -waitForDevice -v -p /dev/tty.UC-232AC uboot-uart-ais.bin
+NOTE: Do not cancel the command execution! The command takes 20+ seconds
+to upload u-boot over serial and run it!
+Outcome:
+Waiting for the OMAP-L138...

+
+Falcon Bootmode (boot linux without booting U-Boot)
+===================================================
+
+The Falcon Mode extends this way allowing to start the Linux kernel directly
+from SPL. A new command is added to U-Boot to prepare the parameters that SPL
+must pass to the kernel, using ATAGS or Device Tree.
+
+In normal mode, these parameters are generated each time before
+loading the kernel, passing to Linux the address in memory where
+the parameters can be read.
+With Falcon Mode, this snapshot can be saved into persistent storage and SPL is
+informed to load it before running the kernel.
+
+To boot the kernel, these steps under a Falcon-aware U-Boot are required:
+
+1. Boot the board into U-Boot.
+Use the "spl export" command to generate the kernel parameters area or the DT.
+U-Boot runs as when it boots the kernel, but stops before passing the control
+to the kernel.
+
+Here the command sequence for the ipam390 board:
+- load the linux kernel image into ram:
+
+U-Boot > nand read c0100000 2 200000 400000
+
+NAND read: device 0 offset 0x200000, size 0x400000
+ 4194304 bytes read: OK
+
+- generate the bootparms image:
+

+
+You can use also the predefined U-Boot Environment variable "setbootparms",
+which will do all the above steps in one command:
+
+U-Boot > print setbootparms
+setbootparms=nand read c0100000 200000 400000;spl export atags c0100000;nand erase.part bootparms;nand write c0000100 180000 20000
