[U-Boot] [PATCH 0/2] Android and arm64 improvement

[Bin Chen]

I rebased the two patches submitted (quite )a while ago on top of 
current U-boot master fb4413295c765aa8c013650984dc2d908964c81d 
(and there were no conflicts).

The first patch added the support of parsing the second area of Android image so 
that it can be used for good. On Poplar board, we are using that area for dtb. 
The first patch shouldn't impact any functionality since 
it is new.

The second patch moves the booti_setup out of booti.c. It was the result of a 
discusion[1] how to better support the arm64 Android image. 

I have boot tested it on Poplar board[2] with additional patch[3] that is 
built on top of the booti. I have hacked version of using bootm but it seems quit 
mess up - need lots of changes in different places ("Shotgun Surgery") to handle 
Android specific and/or arm64 specific code. Now, I feel a separate 
bootandroid command might be a cleaner solution.

That being said, the second patch doesn't depend on or impact any change we 
might have in the future for better Android support.
