[U-Boot-Users] CFG_LOAD_ADDR vs. CONFIG_LOADADDR vs. CFG_TFTP_LOADADDR

[Timur Tabi]

What's the difference between CFG_LOAD_ADDR and CONFIG_LOADADDR?  Looking at the 
code, it looks like their both used as default load addresses, but I don't see 
why they should have different values (they do in most header files).

The README also talks about CFG_TFTP_LOADADDR, but I don't see where that's used 
in the code.

CFG_LOAD_ADDR is what you are supposed to use in the code.

CONFIG_LOADADDR is the value used to initialize the "loadaddr"
variable in the default environment.

I see little reason to define CONFIG_LOADADDR at all.

It ain't used, and should be removed.

Otto Waalkes could take lessons from you.

Then what's the best way to define a default value for the "loadaddr" variable?

Define CONFIG_LOADADDR.

But, as mentioned implicitely before, I see little reason  to  define
the "loadaddr" variable at all.

Define CFG_LOAD_ADDR, and that's it. Having more than one defualt
value seems a broken design to me.
