From: Jerry Huang Chang-Ming.Huang@freescale.com
The new MPC8360EMDS board changes the oscillator to 33.33MHz in order to support QE 500MHz since 2008.
Signed-off-by: Jerry Huang Chang-Ming.Huang@freescale.com CC: Kim Phillips kim.phillips@freescale.com --- cahnges for v2: - fix multiline comment wrong changes for v3: - change the oscillator to 33330000, not 33300000 changes for v4: - add the mandatory history of changes changes for v5: - move the code to platform file from lib/board.c - add 2011 copyright changes for v6: - split into two patch - add the CLKIN33 option for 33.33MHz oscillator - add the readme for CLKIN33 option - add CC
