+Nios II is a 32-bit embedded-processor architecture designed
+specifically for the Altera family of FPGAs.
+
+Please refer to the link for more information on Nios II,
+https://www.altera.com/products/processors/overview.html
+
+Please refer to the link for Linux port and toolchains,
+http://rocketboards.org/foswiki/view/Documentation/NiosIILinuxUserManual
+
+The Nios II port of u-boot is controlled by device tree. Please check
+out doc/README.fdt-control.
+
+To add a new board/configuration (eg, mysystem) to u-boot, you will need
+three files.
+
+1. The device tree source which describes the hardware, dts file.
+ arch/nios2/dts/mysystem.dts
+
+2. Default configuration of Kconfig, defconfig file.
+ configs/mysystem_defconfig
+
+3. The legacy board header file.
+ include/configs/mysystem.h
+
+The device tree source must be generated from your qsys/sopc design
+using the sopc2dts tool. Then modified to fit your configuration. Please
+find the sopc2dts download and usage at the wiki,
+http://www.alterawiki.com/wiki/Sopc2dts
+
+$ java -jar sopc2dts.jar --force-altr -i mysystem.sopcinfo -o mysystem.dts
+
+You will need to add additional properties to the dts. Please find an
+example at, arch/nios2/dts/3c120_devboard.dts.
+
+1. Add "stdout-path=..." property with your serial path to the chosen
+node, like this,
+ chosen {
+ stdout-path = &jtag_uart;
+ };
+
+2. If you use SPI/EPCS or I2C, you will need to add aliases to number
+the sequence of these devices, like this,
+ aliases {
+ spi0 = &epcs_controller;
+ };
+
+Next, you will need a default config file. You may start with
+nios2-generic_defconfig, modify the options and save it.
+
+$ make nios2-generic_defconfig
+$ make menuconfig
+$ make savedefconfig
+$ cp defconfig configs/mysystem_defconfig
+
+You will need to change the names of board header file and device tree,
+and select the drivers with menuconfig.
+
+Nios II architecture --->
+ (mysystem) Board header file
+Device Tree Control --->
+ (mysystem) Default Device Tree for DT control
+
+There is a selection of "Provider of DTB for DT control" in the Device
+Tree Control menu.
+
+( ) Separate DTB for DT control, will cat the dtb to end of u-boot
+binary, output u-boot-dtb.bin. This should be used for production.
+If you use boot copier, like EPCS boot copier, make sure the copier
+copies all the u-boot-dtb.bin, not just u-boot.bin.
+
+( ) Embedded DTB for DT control, will include the dtb inside the u-boot
+binary. This is handy for development, eg, using gdb or nios2-download.
+
+The last thing, legacy board header file describes those config options
+not covered in Kconfig yet. You may copy it from nios2-generic.h.
+
+$ cp include/configs/nios2-generic.h include/configs/mysystem.h
+
+Please change the SDRAM base and size to match your board. The base
+should be cached virtual address, for Nios II with MMU it is 0xCxxx_xxxx
+to 0xDxxx_xxxx.
+
+#define CONFIG_SYS_SDRAM_BASE 0xD0000000
+#define CONFIG_SYS_SDRAM_SIZE 0x08000000
+
+You will need to change the environment variables location and setting,
+too. You may change other configs to fit your board.
+
+After all these changes, you may build and test.
+
+$ export CROSS_COMPILE=nios2-elf- (or nios2-linux-gnu-)
+$ make mysystem_defconfig
+$ make
+
+Enjoy!

+
+This binding specifies what properties available in the device tree
+representation of a Nios II Processor Core.
+

+Qsys system. See more detail in: http://www.alterawiki.com/wiki/Sopc2dts
+

+# This script tests U-Boot's FAT filesystem code's ability to read non-
+# contiguous files.
+
+# When porting the ff.c FAT parsing code into U-Boot, it was found that ff.c
+# always reads files cluster-by-cluster, which results in poor performance.
+# This was solved by adding a patch to ff.c to coalesce reads of adjacent
+# clusters. Since this patch needed to correctly handle non-contiguous files,
+# this test was written to validate that.
+#
+# To execute the test, simply run it from the U-Boot source root directory:
+#
+# cd u-boot
+# ./test/fs/fat-noncontig-test.sh
+#
+# The test will create a FAT filesystem image, record the CRC of a randomly
+# generated file in the image, build U-Boot sandbox, invoke U-Boot sandbox to
+# read the file and validate that the CRCs match. Expected output is shown
+# below. The important part of the log is the penultimate line that contains
+# either "PASS" or "FAILURE".
