Improve U-Boot API detection

2016-03-09T11:45:48+00:00

Until now, ubldr has been trying to locate the U-Boot API using a hint
address (U-Boot's current stack pointer), aligning it to 1MiB and going
over a 3MiB (or 1MiB in case of MIPS) memory region searching for a
valid API signature.

This change introduces an alternative way of doing this, namely the
following:
- both U-Boot's bootelf and go commands actually pass argc and argv to
  the entry point (e.g., ubldr's start function, but they should also
  be passed over to main() transparently)
- so, instead of trying to go and look for a valid API signature, we
  look at the parameters passed to main()
- if there's an option '-a' with argument, which is a valid hexadecimal
  unsigned  long number (x), we try to verify whether we have a valid
  API signature at address x. If so - we use it. If not - we fallback
  to the original way of locating the API signature.

The U-Boot change, which causes the API structure address to be
exported as an environment variable, was committed to mainline U-Boot
as commit 22aa61f707574dd569296f521fcfc46a05f51c48

ubldr.

The changes are mostly dealing with removing unnecessary casts from the U-Boot
API (we're passing only pointers, no obvious reason to cast them to uint32_t),
cleaning up some compiler warnings and using the proper printf format
specifiers in order to be able to compile cleanly for both 32-bit and 64-bit
MIPS targets.
