What determines the load address for "script.bin" ?

[starfry]

Hi, basic knowledge question here...

I was just wondering what determines the load address for "script.bin". I can see that the default environment includes a "scriptaddr" variable that is preset to 0x43100000 but the official archlinuxarm kernel uImage expects it to be loaded at 0x43000000.

The "bootm" command doesn't take this address as an argument (unlike the kernel address and initramfs address) so, either U-Boot tells it in another way, or the kernel must be precompiled to expect it at a given location.

I haven't been able to determine where this is defined. I presume this is a setting within the kernel but I don't know what.

Can anyone enlighten me?
