There is no need for special Driver, AHCI is sufficient for ThunderX, the

is it preferable if this interrupt handler in libahci.c with others, instead

Yeap, just fold it in ahci.c with surrounding #ifdef guard.

Yes, please use #ifdef CONFIG_CAVIUM_ERRATUM_22536 ... and add a
kconfig entry for this to arch/arm64/Kconfig.

Are you sure, this is not a workaround that is based on alternative framework rather on pci device and vendor

do you think CONFIG_ARCH_THUNDER a good alternative?
