[U-Boot] [PATCH 0/3] vexpress64 flash support

[Ryan Harkin]

Whilst adding NOR support for Juno and FVP models, I encountered a 
problem in cfi_flash.c.  It is using "unsigned long" to represent a 
32-bit value.  This does not work on 64-bit systems such as vexpress64.

I fixed it up in patch 1/3, however, I'm not convinced that my mod is
the correct one.  I'd appreciate some help with that one and will respin 
after feedback.

Patch 2/3 may also be unsuitable.  Once I'd added the CFI flash support,
the build failed because tools/envcrc.c includes include/config.h, which 
in turn includes include/configs/vexpress_aemv8a.h, but without a board
defined.  Perhaps there is something missing from the global config that 
means the #errors should not be triggered?  Again, feedback would be 
appreciated here.

The last patch relies on the two previous ones to build and work 
successfully.  I believe it to be the correct approach but welcome 
suggested improvements.

I tested it on Juno R0, R1 and FVP AEMv8 models version "Fast Models
[0.8.6302 (Feb  4 2015)]".  I also tested on Foundation Model version
"ARM V8 Foundation Model r0p0 (model build 9.2.28)", where it failed
gracefully.
