[U-Boot-Users] Target support for qemu -M mips
by Vlad Lungu 17 Jan '08

17 Jan '08

With serial, NE2000, IDE support. Tested in big-endian mode. Memory size hard-coded to 128M for now, so don't play with the -m option.

[U-Boot-Users] [PATCH 1/2] mpc83xx: add support for more system clock performance controls
by Kim Phillips 17 Jan '08

17 Jan '08

System registers that are modified are the Arbiter Configuration Register (ACR), the System Priority Control Register (SPCR), and the System Clock Configuration Register (SCCR).
