Yes, it seems very much as if you were right again. When using ips/ibp everything makes sense, and works. Hm... so that means on MPC512x we should use mpc512x_find_ips_freq(), while on MPC5200 we should use mpc52xx_find_ipb_freq() - but hey, apart from the name these two functions are identical. Grant - how would you like to see this handled? Should we merge these two code-wise identical functions into one? What should be the name, and in which file should we put it? [We need this clock thing for "drivers/net/fs_enet/mii-fec.c"...] 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: w...@denx.de "Don't think; let the machine do it for you!" - E.
