Re: [U-Boot] [PATCH] video/powerpc: don't touch DIU registers that we don't need

Hi Timur,

Several DIU registers were being initialized either unnecessarily or to wrong values.

1. All interrupts were enabled even though there's no interrupt handler. Interrupts were left enabled when booting Linux.

2. Don't configure a dummy area descriptor, since we don't support ADs in U-Boot.

3. Don't configure any write-back buffer registers, since we don't use that mode.

4. The default values for the THRESHOLDS, SYN_POL, and PLUT registers should be used, so don't touch those registers either.

Applied to video/master. I'm sorry for long delay.

Thanks, Anatolij
