This patch adds support for the CycloneV and ArriaV SDRAM controllers. Correction and reporting of SBEs, Panic on DBEs.
Signed-off-by: Thor Thayer <tthayer@xxxxxxxxxx>
---
v2: Use the SDRAM controller registers to calculate memory size
instead of the Device Tree. Update To & Cc list. Add maintainer
information.
v3: EDAC driver cleanup based on comments from Mailing list.
v4: Panic on DBE. Add macro around inject-error reads to prevent
them from being optimized out. Remove of_match_ptr since this
will always use Device Tree.
v5: Addition of printk to trigger function to ensure read vars
are not optimized out.
v6: Changes to split out shared SDRAM controller reg (offset 0x00)
as a syscon device and allocate ECC specific SDRAM registers
to EDAC.
v7: No change. Bump version for consistency.
