/*
* u_boot_first_phase() - check if this is the first U-Boot phase
*
* U-Boot has up to three phases: TPL, SPL and U-Boot proper. Depending on the
* build flags we can determine whether the current build is for the first
* phase of U-Boot or not. If there is no SPL, then this is U-Boot proper. If
* there is SPL but no TPL, the the first phase is SPL. If there is TPL, then
* it is the first phase.
*
* @returns true if this is the first phase of U-Boot
