This is not possible. For example, the IBM 4xx processor hat it's reset vector at 0xFFFFFFFC, so the last 4 bytes in your address space cannot be "reserved for a special purpose" (except this "special purpose" is another boot loader).
- If I use TEXT_BASE = FFFE0000 and simply put the u-boot.bin generated to
FFF00000, will it mess up the addressing in the u-boot?
Yes,. of course. Why do you think you have to ask this question? Isn't this obvious?
- If the answer for 1 is yes, how can I move up the end of flash to
FFF80000 so that the u-boot.bin will fill from FFF00000 to FFF80000 instead of from FFF00000 to FFFFFFFF?
You cannot. At least a branch instruction must be paced at the reset vector, which is 0xFFFFFFFC, which is the end of your "reserved" area.
Please redefine your requirements.
