From aa6ff928980b5d01e1932834c9462e57034de3a1 Mon Sep 17 00:00:00 2001 From: Dan Wei Date: Sat, 22 Jun 2019 10:25:21 -0400 Subject: [PATCH] net/ipn3ke: modify AFU configurations Modify AFU configurations for new BBS (Blue Bitstream) of A10 on N3000 card: - AFU register access: RTL changes the UPL (User Programmable Logic which is the container of vBNG IP) base address and the read/write commands of register indirect access. - Poll the INIT_STS register to wait for the vBNG IP and DDR reset completion. - Refine log for debug: print UPL_version not only for vBNG bit stream, but also for other bit streams.
