New Revision: 226821
URL: http://svn.freebsd.org/changeset/base/226821
Log:
SRAM offset 0x0C04 is used by driver to inform the IPMI/ASF firmware
about the various driver events like load, unload, reset, suspend,
restart, and ioctl operations.
Define driver's event rather than using hard-coded values. We don't
still send suspend/resume event to firmware.
Previously bge(4) used BGE_SDI_STATUS to send events. Because driver
has to access firmware mail box to inform current state, using
BGE_SDI_STATUS register was wrong. The end result was the same as
BGE_SDI_STATUS is 0x0C04.
No functional changes.
