[PATCH 1/4] globalvar: add set_single function

[PATCH 1/4] globalvar: add set_single function

[Rouven Czerwinski]

Instead of overwriting the whole hierarchy beneath a globalvar, the
set_single function only sets the specific globalvar.

[PATCH 2/4] blspec: only reset variable locations, not paths

[Rouven Czerwinski]

Configuration of the loadaddresses for image oftree and initrd can not
be done inside the bootloader spec yet, so using bootloader spec should
not override settings from the environment.

[PATCH 3/4] blspec: fix bootm_data initialization

[Rouven Czerwinski]

Remove initialization of the verbose struct member, it will be
overwritten by the call to bootm_data_init_defaults(). Also remove
members which are initialized in the call.
Verbose should be enabled if either the argument or variable is set, so
|| both.

[PATCH 4/4] fastboot: only unset image, not loadaddr

[Rouven Czerwinski]

In case the board needs to setup the load address of the kernel, don't
overwrite the variable, instead only override the image.

What's the difference between this construct and plain strcmp()?

> +			dev_set_param(&global_device, param->name, val);

And then, why not call dev_set_param directly with "match" as argument?

I would rename "match" to "name" as it describes a single variable name.
Also "globalvar_set" is IMO enough as a function name.
