4. Major Changes

1. Upgrade Intel SoC FPGA TF-A to version socfpga_v2.11.0
   • Based on TF-A version 2.11 official release

---

5. Known Issues and Limitation

1. Uboot + TF-A Boot Flow

   • Supported in altera-opensource/u-boot-socfpga branch:socfpga_v2020.04 onwards

2. TF-A + Unified Extensible Firmware Interface (UEFI) Boot Flow

   • UEFI is end of life
   • It is no longer supported from version socfpga_v2.7.0 onwards

3. TF-A eASIC N5X Support

   • Current release only have support for BL31
   • Hence TF-A only usable as secure monitor for eASIC N5X platform

4. Double-Bit Error Handling in EL3

   • Linux applied SMC service in EL1 which is already supported in TF-A to handling Double-Bit Error in EL3
