This series is to: 1. Enable ECC priming with BIST engine (Patch 1) 2. Add a function to store base address and size of RAM's banks in a 64 bit device private data (Patch 2) 3. Setup the ECC region start and range (Patch 3) 4. Enable ECC 1 bit error, 2 bit error and multiple bit error interrupts (Patch 4) 5. Add CONFIG_K3_INLINE_ECC (Patch 5) 6. Pull the redundant DDR functions to a common location (Patch 6) 7. Remove redundant DDR functions (Patch 7, 8) 8. Fixup DDR size when ECC is enabled (Patch 9) 9. Add ss_cfg reg entry (Patch 10)
Tested on AM62X and AM62A, results: AM62X: https://gist.github.com/santhosh21/c5f07cd921bd2b12d12385f22c698ee6 AM62A: https://gist.github.com/santhosh21/e5fa684d890d65b4034346435213ec8b Things to look in the test log: 1. Time-taken for priming 2. Fixed up DDR size (RAM size =- ECC reserved space). Thanks and Regards, Santhosh.
