2015-03-09hwrng: caam - fix rng_unmap_ctx's DMA_UNMAP size problemYanjiang Jin
Fix rng_unmap_ctx's DMA_UNMAP size problem for caam_rng, else system would report the below calltrace during cleanup caam_rng. Since rng_create_sh_desc() creates a fixed descriptor of exactly 4 command-lengths now, also update DESC_RNG_LEN to (4 * CAAM_CMD_SZ). caam_jr ffe301000.jr: DMA-API: device driver frees DMA memory with different size [device address=0x000000007f080010] [map size=16 bytes] [unmap size=40 bytes] ------------[ cut here ]------------ WARNING: at lib/dma-debug.c:887 Modules linked in: task: c0000000f7cdaa80 ti: c0000000e5340000 task.ti: c0000000e5340000 NIP: c0000000004f5bc8 LR: c0000000004f5bc4 CTR: c0000000005f69b0 REGS: c0000000e53433c0 TRAP: 0700 Not tainted MSR: 0000000080029000 <CE,EE,ME> CR: 24088482 XER: 00000000 SOFTE: 0 GPR00: c0000000004f5bc4 c0000000e5343640 c0000000012af360 000000000000009f GPR04: 0000000000000000 00000000000000a0 c000000000d02070 c000000015980660 GPR08: c000000000cff360 0000000000000000 0000000000000000 c0000000012da018 GPR12: 00000000000001e3 c000000001fff780 00000000100f0000 0000000000000001 GPR16: 0000000000000002 0000000000000000 0000000000000000 0000000000000000 GPR20: 0000000000000000 0000000000000000 ffffffffffffffff 0000000000000001 GPR24: 0000000000000001 0000000000000001 0000000000000000 0000000000000001 GPR28: c000000001556b90 c000000001565b80 c0000000e5343750 c0000000f9427480 NIP [c0000000004f5bc8] .check_unmap+0x538/0x9c0 LR [c0000000004f5bc4] .check_unmap+0x534/0x9c0 Call Trace: [c0000000e5343640] [c0000000004f5bc4] .check_unmap+0x534/0x9c0 (unreliable) [c0000000e53436e0] [c0000000004f60d4] .debug_dma_unmap_page+0x84/0xb0 [c0000000e5343810] [c00000000082f9d4] .caam_cleanup+0x1d4/0x240 [c0000000e53438a0] [c00000000056cc88] .hwrng_unregister+0xd8/0x1c0 Instruction dump: 7c641b78 41de0410 e8a90050 2fa50000 419e0484 e8de0028 e8ff0030 3c62ff90 e91e0030 38638388 48546ed9 60000000 <0fe00000> 3c62ff8f 38637fc8 48546ec5 ---[ end trace e43fd1734d6600df ]--- Signed-off-by: Yanjiang Jin <yanjiang.jin@windriver.com> Acked-by: Kim Phillips <kim.phillips@freescale.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2014-08-25crypto: caam - enable raw data instead of von Neumann dataAlex Porosanu
The sampling of the oscillator can be done in multiple modes for generating the entropy value. By default, this is set to von Neumann. This patch changes the sampling to raw data, since it has been discovered that the generated entropy has a better 'quality'.

2014-08-25crypto: caam - change starting entropy delay valueAlex Porosanu
The entropy delay (the length in system clocks of each entropy sample) for the RNG4 block of CAAM is dependent on the frequency of the SoC. By elaborate methods, it has been determined that a good starting value for all platforms integrating the CAAM IP is 3200. Using a higher value has additional benefit of speeding up the process of instantiating the RNG, since the entropy delay will be increased and instantiation of the RNG state handles will be reattempted by the driver. If the starting value is low, for certain platforms, this can lead to a quite lengthy process. This patch changes the starting value of the length of the entropy sample to 3200 system clocks. In addition to this change, the attempted entropy delay values are now printed on the console upon initialization of the RNG block. While here, a safeguard for yielding the processor was added for ensuring that in very adverse cases, the CPU isn't hogged by the instantiation loop.

2014-08-25crypto: caam - disable RNG oscillator maximum frequency checkAlex Porosanu
The rtfrqmax & rtfrqmin set the bounds of the expected frequency of the oscillator, when SEC runs at its maximum frequency. For certain platforms (f.i. T2080), the oscillator is very fast and thus if the SEC runs at a lower than normal frequency, the ring oscillator is incorrectly detected as being out of bounds. This patch effectively disables the maximum frequency check, by setting a high enough maximum allowable frequency for the oscillator. The reasoning behind this is that usually a broken oscillator will run too slow (i.e. not run at all) rather than run too fast.

At few places in caamhash and caamalg, after allocating a dmable buffer for sg table , the buffer was being modified. As per definition of DMA_FROM_DEVICE ,afer allocation the memory should be treated as read-only by the driver.

2014-06-25crypto: caam - Correct definition of registers in memory mapRuchika Gupta
Some registers like SECVID, CHAVID, CHA Revision Number, CTPR were defined as 64 bit resgisters. The IP provides a DWT bit(Double word Transpose) to transpose the two words when a double word register is accessed. However setting this bit would also affect the operation of job descriptors as well as other registers which are truly double word in nature. So, for the IP to work correctly on big-endian as well as little-endian SoC's, change is required to access all 32 bit registers as 32 bit quantities.

2014-06-20crypto: caam - Introduce the use of the managed version of kzallocHimangi Saraogi
This patch moves data allocated using kzalloc to managed data allocated using devm_kzalloc and cleans now unnecessary kfrees in probe and remove functions. Also, linux/device.h is added to make sure the devm_*() routine declarations are unambiguously available. Earlier, in the probe function ctrlpriv was leaked on the failure of ctrl = of_iomap(nprop, 0); as well as on the failure of ctrlpriv->jrpdev = kzalloc(...); . These two bugs have been fixed by the patch. The following Coccinelle semantic patch was used for making the change: identifier p, probefn, removefn; @@ struct platform_driver p = { .probe = probefn, .remove = removefn, }; @prb@ identifier platform.probefn, pdev; expression e, e1, e2; @@ probefn(struct platform_device *pdev, ...) { <+... - e = kzalloc(e1, e2) + e = devm_kzalloc(&pdev->dev, e1, e2) ... ?-kfree(e); ...+> } @rem depends on prb@ identifier platform.removefn; expression e; @@ removefn(...) { <... - kfree(e); ...> } Signed-off-by: Himangi Saraogi <himangi774@gmail.com> Acked-by: Julia Lawall <julia.lawall@lip6.fr> Reviewed-by: Marek Vasut <marex@denx.de> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
