it's a wiki, it's intended for people to improve it. otoh adding
correction notes is not as good as actually fixing the content.

thanks, I've fixed the typo now. but as my namesake mentioned unless
you are building android use the standard procedure for building linux
kernels, i.e. calling `make` yourself.

ignore the script, it's only of use for those building android, and
they have `mkbootimg`, ... but you can file an ticket in the issue
tracker to discuss the topic (and maybe even improve those scripts ;-)

did you preload script.bin?

wait a second, please stop calling it *my* default .config or *my*,
it's the sun4i_defconfig (or sun4i_crane_defconfig) that came on the
source drop released by Qware from allwinner.

keeping in mind it's a generic kernel, send a patch ;-)
