vexpress64: store env in flash
Add support for storing the environment in CFI NOR flash on Juno and FVP
models.
I also removed some config values that are not used by CFI flash parts.
Juno has 1 flash part with 259 sectors. The first 255 sectors are
0x40000 (256kb) and are followed by 4 sectors of 0x10000 (64KB).
FVP models simulate a 64MB NOR flash part at base address 0x0FFC0000.
This part has 256 x 256kb sectors. We use the last sector to store the
environment.
To save the NOR flash to a file, the following parameters should be
passed to the model:
-C bp.flashloader1.fname=${FILENAME}
-C bp.flashloader1.fnameWrite=${FILENAME}
Foundation models don't simulate the NOR flash, but having NOR support
in the u-boot binary does not harm: attempting to write to the NOR will
fail gracefully.
