[U-Boot] sandbox question

[TigerLiu at viatech.com.cn]

Hi, Simon:
Sandbox concept is a very good idea to test uboot's non-platform part
code.

I have a question about compiling uboot sandbox branch:
1. It seems sandbox branch could be compiled by gcc compiler on a x86
platform.
   Not need to set cross compiler tool chains.
   And after finished compiling, it could be run on a x86 environment.
   So, my question is:
   Arm cross compiler tool chains could produce different obj file for a
same .C file.
   The obj file for a same .C file by arm cross compiler tool chain is
not different with the obj file produced by a x86 gcc tool.
   (On my x86 platform, defaut gcc is a x86 version)

   So, for more precise test for non-platform code:
    User should compile sandbox branch with an arm cross compiler tool
chain.
    And should run it on an arm linux environment?

Best wishes,
