Benoît Thébaudeau 2979b26323 autoconfig.mk: Make it possible to define configs from other configs
Give more flexibility to define configs that can be interpreted by make, e.g. to
define fallback values of configs like in the example below.

Before this change, the config lines:
 #define CONFIG_SPL_MAX_SIZE	2048
 #define CONFIG_SPL_PAD_TO	CONFIG_SPL_MAX_SIZE
would have been changed in autoconfig.mk into:
 CONFIG_SPL_MAX_SIZE=2048
 CONFIG_SPL_PAD_TO="CONFIG_SPL_MAX_SIZE"

Hence, a make recipe using as an argument to $(OBJCOPY):
 --pad-to=$(CONFIG_SPL_PAD_TO)
would have issued:
 --pad-to="CONFIG_SPL_MAX_SIZE"
which means nothing for $(OBJCOPY) and makes it fail.

Thanks to this change, the config lines above are changed in autoconfig.mk into:
 CONFIG_SPL_MAX_SIZE=2048
 CONFIG_SPL_PAD_TO=$(CONFIG_SPL_MAX_SIZE)

Hence, the make recipe above now issues:
 --pad-to=2048
as expected from the defined config.

This directory contains scripts that help to perform certain actions
that need to be done frequently when working with U-Boot.

They are meant as EXAMPLE code, so it is very likely  that  you  will
have to modify them before use.


Short description:
==================

dot.kermrc:

	Example for "~/.kermrc" Kermit init file for use with U-Boot

	by Wolfgang Denk, 24 Jun 2001

flash_param:

	"kermit" script to automatically initialize the environment
	variables on your target. This is most useful during
	development when your environment variables are stored in an
	embedded flash sector which is erased whenever you install a
	new U-Boot image.

send_cmd:

	send_cmd U_BOOT_COMMAND

	"kermit" script to send a U-Boot command and print the
	results. When used from a shell with history (like the bash)
	this indirectly adds kind of history to U-Boot ;-)

	by Swen Anderson, 10 May 2001

send_image:

	send_image FILE_NAME OFFSET

	"kermit" script to automatically download a file to the
	target using the "loadb" command (kermit binary protocol)
