* powerpc/t4qds: Add alternate serdes protocols to align with A-007186Shaohui Xie2014-06-05-0/+172
| | | | | | | | | | | | | | | | | A-007186: SerDes PLL is calibrated at reset. It is possible for jitter to increase and cause the PLL to unlock when the temperature delta from the time the PLL is calibrated exceeds +56C/-66C when using X VDD of 1.35 V (or +70C/-80C when using XnVDD of 1.5 V). No issues are seen with LC VCO. Only the protocols using Ring VCOs are impacted. Workaround: For all 1.25/2.5/5 GHz protocols, use LC VCO instead of Ring VCO, this need to use alternate serdes protocols. The alternate option has the same functionality as the original option; the only difference being LC VCO rather than Ring VCO.

* powerpc/mpc85xx: Add workaround for erratum A007212York Sun2014-04-22-0/+95
| | | | | | | | | | | | | | | | | Erratum A007212 for DDR is about a runaway condition for DDR PLL oscilliator. Please refer to erratum document for detail. For this workaround to work, DDR PLL needs to be disabled in RCW. However, u-boot needs to know the expected PLL ratio. We put the ratio in a reserved field RCW[18:23]. U-boot will skip this workaround if DDR PLL ratio is set, or the reserved field is not set. Workaround for erratum A007212 applies to selected versions of B4/T4 SoCs. It is safe to apply the workaround to all versions. It is helpful for upgrading SoC without changing u-boot. In case DDR PLL is disabled by RCW (part of the erratum workaround), we need this u-boot workround to bring up DDR clock. Signed-off-by: York Sun <yorksun@freescale.com>
