[Verse 1] Custom silicon waits for code to run Standard kernels can't see what you've done Board support packages need their place In the kernel tree's structured space Device trees describe your memory map GPIO pins and interrupt gaps [Chorus] Cross compile, cross the bridge Hardware abstraction is your privilege Port the kernel, make it fit Abstract, compile, test, commit Architecture layers separate the code From metal paths where electrons flow [Verse 2] Machine definitions hold the key Platform data sets your hardware free Clock frameworks need their frequencies right Power domains control the might MMIO regions mapped with care Virtual addresses everywhere [Chorus] Cross compile, cross the bridge Hardware abstraction is your privilege Port the kernel, make it fit Abstract, compile, test, commit Architecture layers separate the code From metal paths where electrons flow [Bridge] Bootloaders pass the device tree blob Kernel parses every hardware job Drivers probe and find their match Platform bus helps them attach DMA coherency matters most When your custom silicon is the host [Verse 3] Toolchain targets your CPU type GCC flags keep assembly right Kconfig options gate your build Makefiles do what they are willed Testing early, testing often When hardware bugs make kernels soften [Chorus] Cross compile, cross the bridge Hardware abstraction is your privilege Port the kernel, make it fit Abstract, compile, test, commit Architecture layers separate the code From metal paths where electrons flow [Outro] From silicon dreams to running streams Your custom board joins Linux teams Architecture porting never ends As hardware evolution transcends
