If anyone has any objections, please let me know. ------------------ From: Daire McNamara [ Upstream commit 6d473a5a26136edf55c435a1c433e52910e03926 ] The SEC and DED interrupt bits are laid out the wrong way round so the SEC interrupt handler attempts to mask, unmask, and clear the DED interrupt and vice versa. Correct the bit offsets so that each interrupt handler operates properly.
