ppc4xx: PPC44x MQ initialization

2008-10-17T11:02:42Z

Set the MQ Read Passing & MCIF Cycle limits to the recommended by AMCC values. This fixes the occasional 440SPe hard locking issues when the 440SPe's dedicated DMA engines are used (e.g. by the h/w accelerated RAID driver). Previously the appropriate initialization had been made in Linux, by the ppc440spe ADMA driver, which is wrong because modifying the MQ configuration registers after normal operation has begun is not supported and could have unpredictable results. Comment from Stefan: This patch doesn't change the resulting value of the MQ registers. It explicitly sets/clears all bits to the desired state which better documents the resulting register value instead of relying on pre-set default values.

ppc4xx: Reset and relock memory DLL after SDRAM_CLKTR change

2008-10-08T09:36:23Z

After changing SDRAM_CLKTR phase value rerun the memory preload initialization sequence (INITPLR) to reset and relock the memory DLL. Changing the SDRAM_CLKTR memory clock phase coarse timing adjustment effects the phase relationship of the internal, to the PPC chip, and external, to the PPC chip, versions of MEMCLK_OUT.

ppc4xx: Remove CONFIG_CS8952_PHY define

2008-09-08T08:27:56Z

Since this define is only used on one board that was never really in production, removing this compile time option doesn't hurt and makes the code more readable. Signed-off-by: Stefan Roese

ppc4xx: Fix compilation warning for PIP405

2008-09-08T08:27:51Z

This patch fixes a compilation warning for the PIP405 board. It moves the #ifndef CONFIG_CS8952_PHY define a little so that the warning doesn't occur anymore. I am a little unsure if this #ifdef is at the correct place now or if it could be removed completely. This needs to get tested on the PIP405 board. Signed-off-by: Stefan Roese
