| * | powerpc/t4qds: Add alternate serdes protocols to align with A-007186 | Shaohui Xie | 2014-06-05 | 1 | -2/+2 |
| | | | | | | | | | | | | | | | | | | 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/t4240: updated rcw_cfg to align with default hardware configuration | Shaohui Xie | 2013-10-16 | 1 | -4/+4 |
| | | | | | | | | | | Default configuration has been changed, the most important one is DDR ref_clock which is changed from 66.67MHz to 133.33MHz. so the ratio need to change from 24x to 12x to keep the DDR frequency. There are also some other optimise to align with default configuration. Signed-off-by: Shaohui Xie <Shaohui.Xie@freescale.com> | ||||
| * | T4240/ramboot: enable PBL tool for T4240 | Shaohui Xie | 2013-05-24 | 1 | -0/+7 |
| Added a default RCW(1_28_6_12) and PBI configure file for T4240, so it can use PBL tool to produce the ramboot image. Signed-off-by: Shaohui Xie <Shaohui.Xie@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com> | |||||
