[PATCH 00/10] ECC Series

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.
