Isn't stdbool.h more for backward compatability for user space
programs, so only newer C99 aware programs can opt-in to the new data
type?  Linux for example doesn't use stdbool.h, it puts the definition
of "bool" in types.h, and true/false in stddef.h.  Since, like Linux,
u-boot is a single codebase, all the data types can go in a common
place and not have to worry about breaking old programs with new
types.

If you cc me on newer versions of the patch I can help verify on
tegra, which uses USE_PRIVATE_LIBGCC.
