[Verse 1] Starting with a custom board in hand Silicon dreams that need to understand The kernel's voice through abstraction layers Architecture specific code that never wavers Device trees mapping every pin and port Hardware abstraction is our first resort [Chorus] Port it right, map it tight, BSP in sight HAL beneath, drivers reach, make it all complete Boot sequence, mem sequence, interrupt routine Architecture porting keeps the system clean Port it right, map it tight, that's our engineering might [Verse 2] Board support package holds the secret keys Platform init and memory boundaries Clock domains spinning at their prescribed rates GPIO functions that the kernel delegates Machine specific files define the way Hardware meets software every single day [Chorus] Port it right, map it tight, BSP in sight HAL beneath, drivers reach, make it all complete Boot sequence, mem sequence, interrupt routine Architecture porting keeps the system clean Port it right, map it tight, that's our engineering might [Bridge] From bootloader handoff to the running state Memory maps and register layouts Cache coherency and pipeline stages Architecture porting through the ages Generic code above, specific below That's the porting way we need to know [Verse 3] Cross compilation for the target arch Debug interfaces help us through the march Power management states and thermal zones Architecture specific calling zones System calls bridge the user kernel space Porting fundamentals keep us in the race [Chorus] Port it right, map it tight, BSP in sight HAL beneath, drivers reach, make it all complete Boot sequence, mem sequence, interrupt routine Architecture porting keeps the system clean Port it right, map it tight, that's our engineering might [Outro] When silicon meets the software dreams Architecture porting bridges all the seams BSP foundation, HAL translation Full stack system integration
