This is NOT correct.

I dare to suggest it for standard on ALL 82xx boards

There is no reason for such a restriction. For me, the de facto standard is 0xFFF00000.

You are right, in that there is no reason for _a_n_y_ restriction But: - good idea to boot at 0xFE000100 (32M boot flash/rom), this is the highest 32M which can be big enough for most embedded systems - good idea to leave the flash at the reset address (there may be any data to use later e.g. ramdisk or flash filesystem and of course the kernel itself) - good idea NOT overlap the internal area with the boot flash - good idea NOT modify the IMMR reset value, which (in case of 0xF0000000) may start at the common/usual IO - at the highest 256M area - today, for the 8280 the internal area is 256K, it is a matter of time to grow over 1M ...

As far as I know the uboot include/configs/*.h files use many value, even very strange ones, the 0xf0000000 is not the minority. (For me, the de facto standard is this.)
