The general procedure is always the same:
make est8260_config
make oldconfig or make menuconfig
make dep
make pImage
"make oldconfig" is good if you don't want to change the default
configuration (which is probably a good idea to get a system running
first), while "make menuconfig" is goot to modify the configuration
to your specific needs (you should know what you're doing then, of
course).

This is done automatically with "make pImage".

This depends. If you use an uncompressed kernel image (build with
mkimage option "-C none") you'll see " Loading %s ... ", with a
compressed image you'll get " Uncompressing %s ... ".

Probably you made some errors when building the image - that's why
there is the "pImage" make target, to provide a working solution.

You cannot (simply) do this. The Linux kernel expects a lot of
hardware initialization before it can run, and even then it expects a
couple of arguments passed to it.
