From 6c9789de2a02755101f757789ffcb17312f3fa9b Mon Sep 17 00:00:00 2001 From: Anton Vorontsov Date: Sun, 11 Jan 2009 18:30:13 +0300 Subject: powerpc/83xx: Make serial ports work on MPC8315E-RDB w/ FSL U-Boots FSL U-Boots use /soc8315@e0000000 node to search and fixup serial nodes' clock-frequency properties. Though in upstream kernels we use new naming convention -- for IMMR address space dts files specify /immr@e0000000 nodes. This makes FSL U-Boots fail to fixup the clock frequencies, and that leads to serial ports misbehaviour. We can workaround the issue by filling the clock frequency values manually. p.s. For the same reason FSL U-Boots fail to fixup MAC addresses for ethernet nodes, so users should either change the .dts file locally or set MAC address via `ifconfig hw ether' command.
