Second, I asked you before to implement this similar like the initrd location can be controlled using the "initrd_high" environment variable (see my message Tue, 07 Aug 2007 21:21:19 +0200). AFAICT you never replied to this.
I believe Andy got this from me. I keyed off his statement that "The blob must be within CFG_BOOTMAPSZ..." so I suggested he compare of_flat_tree to CFG_BOOTMAPSZ, since that was the criteria that he stated.

I'm ignorant of the particulars, but I assumed from the above referenced discussion/description that CFG_BOOTMAPSZ is a better criteria than initrd_high. True? False?
I don't think it's better. CFG_BOOTMAPSZ is a hard coded limit. initrd_high (or fdt_high or whatever you will call it) allows you to use the same value as default, but overwrite it on systems which don't need it or have additional restrictions, i. e. it giveds you added flexibility. This is IMHO a Good Thing (TM).
