- Subject: [PATCH] bgmac: fix MAC soft-reset bit for corerev > 4
- MIME-Version: 1.0
- Content-Type: text/plain; charset=UTF-8
- Content-Transfer-Encoding: 8bit
- Only core revisions older than 4 use BGMAC_CMDCFG_SR_REV0. This mainly
- fixes support for BCM4708A0KF SoCs with Ethernet core rev 5 (it means
- only some devices as most of BCM4708A0KF-s got core rev 4).
- This was tested for regressions on BCM47094 which doesn't seem to care
- which bit gets used.
