powerpc/8xx: Add DT node for using the SEC engine of the MPC885 (e738c5f1) · Commits · 戴 / test

The MPC885 has SEC engine version 1.2 with the following details: - Number of Crypto channels: 1 - Exec Units: DEU, MDEU and AESU - Available descriptors: 00010, 00100, 00110, 01000, 11000, 11010 It is also supposed to have descriptor 00000, but it doesn't work properly so we keep it out for the moment.
