* ENGR00319415 pcie: random link down issue after warm-rstRichard Zhu2017-04-05-0/+18
| | | | | | | | | | | | | | | | | | | | | There are about 0.02% percentage on some imx6q/dl/solo hw boards, random pcie link down when warm-reset is used. Make sure to clear the ref_ssp_en bit16 of gpr1 before warm-rst, and set ref_ssp_en after the pcie clks are stable to workaround it. rootcause: * gpr regisers wouldn't be reset by warm-rst, while the ref_ssp_en is required to be reset by pcie. (work-around in u-boot) * ref_ssp_en should be set after pcie clks are stable. (work-around in kernel) Signed-off-by: Richard Zhu <r65037@freescale.com> (cherry picked from commit 5cc825b12c6b86a22f1a6a0535b52cf3ee142e77) Signed-off-by: Peng Fan <Peng.Fan@freescale.com> (cherry picked from commit 6193cf4e3384a59e29546d13a67657f7faeafc9e) (cherry picked from commit 7b4aabeddffabca46d7d6e7ef2611de468a6b4f7)

* MLK-12534 mx6: shutdown vddpu and PCIE phy to save powerYe Li2017-04-05-0/+42
| | | | | | | | | | | | | | | | | | | Shutdown VDDPU and PCIE phy to save power. For PCIE, the i.MX6SL and i.MX6UL does not have this module, so don't need it. For VDDPU, the i.MX6UL does not have GPU, does not need it. And on i.MX6QP there is narrow window that PRE driver is ready but GPU driver probe later, and the later GPU driver turn on PU may cause 'PRE hang' issue. To simplify thing, do not turn off PU in u-boot.

* MLK-12452-1 FEC: Update fec driver to support two MDIOYe Li2017-04-05-1/+24
| | | | | | | | | | | | | | | | | | | | On i.MX6SX, 6UL and 7D, there are two enet controllers each has a MDIO port. Some boards share the MDIO port for the two enets. So introduce a configuration CONFIG_FEC_MXC_MDIO_BASE to indicate the MDIO port for sharing. In Kconfig, user needs enable CONFIG_FEC_MXC_SHARE_MDIO first to enter the CONFIG_FEC_MXC_MDIO_BASE. Without defining this configuration, the enet will uses own MDIO port. Also add this configurationfor FEC DM driver, since the ENET PHY currently does not support FDT. Modify the dev_id for DM driver, the first fec will set dev_id with 0, while second fec sets the dev_id with 1. So the MII bus name won't be duplicated. Then we can add two FEC devices from DTB.

Support user defined logo file, if there is no logo file, it will draw a black border around a white screen. If need to enable EPDC, a waveform file is required to let all work.

So for these two platform, set the erase threshold to gf/2 and if bitflip detected, GPMI driver will correct the data to all 0xFF. Also updated the imx6qp dts file to ditinguish the GPMI module for i.MX6Q with the one for i.MX6QP. " In this patch, i.MX6UL is added and threshold changed to use ecc_strength.

The threshold is set based on the truth: "A single 0 bit will lead to gf_len(13 or 14) bits 0 after the BCH do the ECC." For the sake of safe, we will set the threshold with half the gf_len, and do not make it bigger the ECC strength. [1] count the bitflips of the current ECC chunk, assume it is N. [2] if the (N <= threshold) is true, we continue to read out the page with ECC disabled. and we count the bitflips again, assume it is N2. (We read out the whole page, not just a chunk, this makes the check more strictly, and make the code more simple.) [3] if the (N2 <= threshold) is true again, we can regard this is a erased page. This is because a real erased page is full of 0xFF(maybe also has several bitflips), while a page contains the 0xFF data will definitely has many bitflips in the ECC parity areas. [4] if the [3] fails, we can regard this is a page filled with the '0xFF' data. " Signed-off-by: Peng Fan <peng.fan@nxp.com> (cherry picked from commit ceb324a2914487aa517a6c70a06a20b5e3438fda)

* MLK-11718-2: mtd: nand: change the BCH layout setting for large oob NANDHan Xu2017-04-05-38/+118
| | | | | | | | | | | | | | | | | | | | | | | | | | | The cod change updated the NAND driver BCH ECC layout algorithm to support large oob size NAND chips(oob > 1024 bytes). Current implementation requires each chunk size larger than oob size so the bad block marker (BBM) can be guaranteed located in data chunk. The ECC layout always using the unbalanced layout(Ecc for both meta and Data0 chunk), but for the NAND chips with oob larger than 1k, the driver cannot support because BCH doesn’t support GF 15 for 2K chunk. The change keeps the data chunk no larger than 1k and adjust the ECC strength or ECC layout to locate the BBM in data chunk. General idea for large oob NAND chips is 1.Try all ECC strength from the minimum value required by NAND spec to the maximum one that works, any ECC makes the BBM locate in data chunk can be chosen. 2.If none of them works, using separate ECC for meta, which will add one extra ecc with the same ECC strength as other data chunks. This extra ECC can guarantee BBM located in data chunk, of course, we need to check if oob can afford it.
