The rtl8139 specification says the configuration registers can be accessed through PCI memory mapping or PCI IO mapping. The u-boot driver uses PCI memory mapping, but it doesn't work, so I changed it to PCI IO mapping. The driver of rtl8139 in Linux Kernel also uses PCI IO mapping to access the configuration registers. > >Best regards, > >Wolfgang Denk > >-- >DENX Software Engineering GmbH, MD: Wolfgang Denk & Detlev Zundel >HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany >Phone: (+49)-8142-66989-10 Fax: (+49)-8142-66989-80 Email: wd at denx.de >Nearly everyone is in favor of going to heaven but too many are >hoping they'll live long enough to see an easing of the entrance >requirements.
