boot command first.

+Note: If you wish to generate Windows versions of the utilities in
+ the tools directory you can use the MinGW toolchain
+ (http://www.mingw.org). Set your HOST tools to the MinGW
+ toolchain and execute 'make tools'. For example:
+
+ $ make HOSTCC=i586-mingw32msvc-gcc HOSTSTRIP=i586-mingw32msvc-strip tools

+ Binaries such as tools/mkimage.exe will be created which can

U-Boot is intended to be simple to build. After installing the
sources you must configure U-Boot for one specific board type. This
is done by typing:
autoscript - if set to "yes" commands like "loadb", "loady",
"bootp", "tftpb", "rarpboot" and "nfs" will attempt
to automatically run script images (by internally
- calling "autoscript").
+ calling "source").
autoscript_uname - if script image is in a format (FIT) this
variable is used to get script subimage unit name.
