Appropriate toolchain are necessary to generate include/autoconf.mk
for all the architectures supported by U-Boot. Most of them are available
-at the kernel.org site, some are not provided by kernel.org.
-
-The default per-arch CROSS_COMPILE used by this tool is specified by
-the list below, CROSS_COMPILE. You may wish to update the list to
-use your own. Instead of modifying the list directly, you can give
-them via environments.
+at the kernel.org site, some are not provided by kernel.org. This tool uses
+the same tools as buildman, so see that tool for setup (e.g. --fetch-arch).
