2. Since we don't implement a hwconfig command, i.e. we're working

toggling a particular option will need a reboot to take
effect. So, for now it's advised to always reboot the
target after modifying the hwconfig variable.

In case of the new uImage argument syntax, the address portion of any argument
can be omitted. If <addr3> is omitted, then it is assumed that image at
-<addr2> should be used. Similarly, when <addr2> is omitted, is is assumed that
+<addr2> should be used. Similarly, when <addr2> is omitted, it is assumed that
image at <addr1> should be used. If <addr1> is omitted, it is assumed that the
current image address is to be used. For example, consider the following
commands:
The following picture shows how the new uImage is prepared. Input consists of
image source file (.its) and a set of data files. Image is created with the
help of standard U-boot mkimage tool which in turn uses dtc (device tree
-compiler) to produce image tree blob (.itb). Resulting .itb file is is the
+compiler) to produce image tree blob (.itb). Resulting .itb file is the
actual binary of a new uImage.

+Providing 'make' flags
+======================
+
+U-Boot's build system supports a few flags (such as BUILD_TAG) which affect
+the build product. These flags can be specified in the buildman settings
+file. They can also be useful when building U-Boot against other open source
+software.
+
+[make-flags]
+at91-boards=ENABLE_AT91_TEST=1
+snapper9260=${at91-boards} BUILD_TAG=442
+snapper9g45=${at91-boards} BUILD_TAG=443
+
+This will use 'make ENABLE_AT91_TEST=1 BUILD_TAG=442' for snapper9260
+and 'make ENABLE_AT91_TEST=1 BUILD_TAG=442' for snapper9g45. A special
+variable ${target} is available to access the target name (snapper9260 and
+snapper9g20 in this case). Variables are resolved recursively.
+
+It is expected that any variables added are dealt with in U-Boot's
+config.mk file and documented in the README.
