1 Altera SoCFPGA ECC Manager
2 This driver uses the EDAC framework to implement the SOCFPGA ECC Manager.
3 The ECC Manager counts and corrects single bit errors and counts/handles
4 double bit errors which are uncorrectable.

54 in a shared register instead of individual IRQs like the Cyclone5
55 and Arria5. Therefore the device tree is different as well.

235 Stratix10 SoCFPGA ECC Manager (ARM64)
236 The Stratix10 SoC ECC Manager handles the IRQs for each peripheral
237 in a shared register similar to the Arria10. However, Stratix10 ECC
238 requires access to registers that can only be read from Secure Monitor
239 with SMC calls. Therefore the device tree is slightly different. Note
240 that only 1 interrupt is sent in Stratix10 because the double bit errors
241 are treated as SErrors in ARM64 instead of IRQs in ARM32.
