Some memories provide ECC detection and/or correction. For software which wants to check memory, it is helpful to see which regions provide this feature.
Add this as a property of the /memory nodes, since it presumably follows the hardware-level memory system.
Signed-off-by: Simon Glass sjg@chromium.org
Changes in v7:
- Drop unnecessary |
- Add a blank line between properties
Changes in v6:
- Use a number of bits instead of a string property
- Fix inidcates typo
Changes in v5:
- Redo to make this property specific to ECC
- Provide properties both for detection and correction
Changes in v3:
- Add new patch to update the /memory nodes
