2017-12-12mmc: sdhci-of-esdhc: fix eMMC couldn't work after kexecyinbo.zhu
The bit eSDHC_TBCTL[TB_EN] couldn't be reset by eSDHC_SYSCTL[RSTA] which is used to reset for all. The driver should make sure it's cleared before card initialization, otherwise the initialization would fail. Signed-off-by: yinbo.zhu <yinbo.zhu@nxp.com>
2017-12-12PCI: layerscape: Change default error response behaviorMinghuan Lian
[modify to adapt to 4.9, pcie have member pp instead of pci] By default, when the PCIe controller experiences an erroneous completion from an external completer for its outbound non-posted request, it sends an OKAY response to the device's internal AXI slave system interface. However, this default system error response behavior cannot be used for other types of outbound non-posted requests. For example, the outbound memory read transaction requires an actual ERROR response, like UR completion or completion timeout. Fix this by forwarding the error response of the non-posted request.

2017-12-12PCI: Disable MSI for Freescale Layerscape PCIe RC modeHou Zhiqiang
[context adjustment] The Freescale PCIe controller advertises the MSI/MSI-X capability in both RC and Endpoint mode, but in RC mode it doesn't support MSI/MSI-X by itself; it can only transfer MSI/MSI-X from downstream devices. Add a quirk to prevent use of MSI/MSI-X in RC mode.

2017-12-12crypto: testmgr - don't DMA map IV from stack in test_skcipher()Horia Geantă
Fix the "DMA-API: device driver maps memory from stack" warning generated when crypto accelerators map the IV. Note: while so far this has been only a warning and thus a theoretical issue, on latest kernel trees ablkcipher algorithms fail when IV is on the stack. Both caam/jr and caam/qi2 fail in the same way, i.e. same incorrect ciphertexts. Below is log for caam/qi2: alg: skcipher: Test 1 failed (invalid result) on encryption for cbc-aes-caam-qi2 00000000: ff 04 80 c3 af 64 47 db 3a 5c b9 b8 91 40 04 8f alg: skcipher: Test 1 failed (invalid result) on encryption for cbc-3des-caam-qi2 00000000: 22 11 b7 06 29 2a 88 cc 75 46 f4 14 8f d0 44 68 00000010: fe 08 88 30 8d d7 b3 01 21 ca 2d 46 0f 81 2e b6 00000020: ab 2f 38 52 79 00 42 82 5e 31 87 ac 8c 0d 19 88 00000030: 0a 27 5b 4b 6c aa f7 10 80 47 b6 81 83 58 7c 0a 00000040: 63 a5 f7 78 aa 05 11 56 9d 99 06 1d fb 98 01 28 00000050: 8a c0 86 7b 68 62 0c 66 84 b3 31 25 60 ad 13 65 00000060: 54 05 2f cd 4f 9a 1e e3 87 51 dc 11 a7 74 15 c4 00000070: 7a df 68 24 34 50 e6 5e 41 ba 98 48 ca 67 9a 6f alg: skcipher: Test 1 failed (invalid result) on encryption for cbc-des-caam-qi2 00000000: 52 ee 01 1b 1b a9 59 c7 a6 f5 ea 74 bf 8f f2 2c 00000010: fe d4 df 4a 50 64 3f 2a alg: skcipher: Test 1 failed (invalid result) on encryption for ctr-aes-caam-qi2 00000000: 4a 3d 28 7a e5 18 b7 84 ce 38 e2 f5 b2 86 58 0b 00000010: a1 04 9f 8f f5 a4 48 bd 0f c6 f3 af 6e d6 cb b3 00000020: 4c f1 52 30 3e bf bd d8 b2 9d 47 a0 40 42 dd 67 00000030: 70 2d 63 f3 1c 9e 96 07 75 29 1e ca db b2 35 ce alg: skcipher: Test 1 failed (invalid result) on encryption for rfc3686-ctr-aes-caam-qi2 00000000: 26 56 7f bb 8d 68 27 e3 52 e7 0f 51 ee 4f ae 03 alg: skcipher: Test 1 failed (invalid result) on encryption for xts-aes-caam-qi2 00000000: bf 84 80 16 02 00 ec 59 b2 d7 dc 2a 50 22 23 95 00000010: a8 e1 f2 65 15 72 67 1e e3 39 86 6b 4d 27 48 87 Signed-off-by: Horia Geantă <horia.geanta@nxp.com>
