Subject: [PATCH] bgmac: fix MAC soft-reset bit for corerev > 4

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.
