Author: ian Date: Mon Aug 13 23:53:11 2018 New Revision: 337731 URL: https://svnweb.freebsd.org/changeset/base/337731 Log: Export the eeprom device size via readonly sysctl. Also export the write page size and address size, although they are likely to be inherently less-interesting values outside of the driver.
