The ESM (Error Signaling Module) is used to route error signals within the K3 SoCs somewhat similar to interrupts. The handling for these is different though, and can be routed for hardware error handling, to be handled by safety processor or just as error interrupts handled by the main processor. The u-boot level ESM driver is just used to configure the ESM signals so that they get routed to proper destination. Signed-off-by: Tero Kristo <t-kristo@ti.com>
