Current implementation limits the BCH8_CODE_HW only for AM33xx device family. (using CONFIG_AM33XX). However, other SoC families (like TI81xx) also have ELM hardware module, and can support ECC error detection using ELM.
This patch
- removes CONFIG_AM33xx Thus this driver can be reused by all devices having ELM h/w engine.
Do you have an overview, which TI devices actually have this ELM h/w engine integrated? Especially if its integrated in the OMAP3530 SoC? I'm currently scanning the users manual and can't find any reference to this IP block.
Thanks, Stefan
