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 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 dtschema/schemas/memory.yaml | 15 +++++++++++++-- 1 file changed, 13 insertions(+), 2 deletions(-)
