class LsuPlugin extends FiberPlugin with DBusAccessService with LsuCachelessBusProvider with LsuService with CmoService

The LsuPlugin does many things : - Handle the AGU (Address Generation Unit) - Interface with the L1 cache - Handle the MMU integration - Implement the PMA checks(Physical Memory Access) - Implement the IO accesses - Implement the AMO/LR/SC instructino - Impplement a store buffer - Implement the prefetching request - Implement RISC-V debug triggers related to memory load/store

So, it has a lot of different functionalities which sometimes are thigtly coupled together in order to reduce area and increase FMax which can make it challenging to read.
