* crypto: inside-secure - enable context reuseAntoine Tenart2019-06-063-0/+16
| | | | | | | | | The context given to the crypto engine can be reused over time. While the driver was designed to allow this, the feature wasn't enabled in the hardware engine. This patch enables it. Signed-off-by: Antoine Tenart <antoine.tenart@bootlin.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: inside-secure - change returned error when a descriptor reports an errorAntoine Tenart2019-06-061-1/+1
| | | | | | | | | | This patch changes the error reported by the Inside Secure SafeXcel driver when a result descriptor reports an error, from -EIO to -EINVAL, as this is what the crypto framework expects. This was found while running the crypto extra tests. Signed-off-by: Antoine Tenart <antoine.tenart@bootlin.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: inside-secure - improve the result error format when displayedAntoine Tenart2019-06-061-1/+1
| | | | | | | | | | The result descriptors contain errors, which are represented as a bitmap. This patch updates the error message to not treat the error as a decimal value, but as an hexadecimal one. This helps in knowing the value does not have a direct meaning (the set bits themselves have).

* crypto: inside-secure - remove useless checkAntoine Tenart2019-06-061-13/+11
| | | | | | | | | | | When sending an ahash request, the code checks for the extra variable not to be 0. This check is useless as the extra variable can't be 0 at this point (it is checked on the line just before). This patch does not modify the driver behaviour in any way.

* crypto: atmel-i2c - add support for SHA204A random number generatorArd Biesheuvel2019-05-305-0/+211
| | | | | | | | | | | | | | The Linaro/96boards Secure96 mezzanine contains (among other things) an Atmel SHA204A symmetric crypto processor. This chip implements a number of different functionalities, but one that is highly useful for many different 96boards platforms is the random number generator. So let's implement a driver for the SHA204A, and for the time being, implement support for the random number generator only.

* crypto: atmel-ecc - add support for ACPI probing on non-AT91 platformsArd Biesheuvel2019-05-302-6/+8
| | | | | | | | | | | | | | | | | | | The Atmel/Microchip EC508A is a I2C device that could be wired into any platform, and is being used on the Linaro/96boards Secure96 mezzanine adapter. This means it could be found on any platform, even on ones that use ACPI enumeration (via PRP0001 devices). So update the code to enable this use case. This involves tweaking the bus rate discovery code to take ACPI probing into account, which records the maximum bus rate as a property of the slave device. For the atmel-ecc code, this means that the effective bus rate should never exceed the maximum rate, unless we are dealing with buggy firmware. Nonetheless, let's just use the existing plumbing to discover the bus rate and keep the existing logic intact.

* i2c: acpi: permit bus speed to be discovered after enumerationArd Biesheuvel2019-05-301-2/+4
| | | | | | | | | | | | | | | Currently, the I2C ACPI enumeration code only permits the max bus rate to be discovered before enumerating the slaves on the bus. In some cases, drivers for slave devices may require this information, e.g., some ATmel crypto drivers need to generate a so-called wake token of a fixed duration, regardless of the bus rate. So tweak the code so i2c_acpi_lookup_speed() is able to obtain this information after enumeration as well.

This replaces: - print_hex_dump(KERN_ERR ...) inside #ifdef DEBUG with print_hex_dump_debug(...) - dev_err() inside #ifdef DEBUG with dev_dbg() - printk(KERN_ERR ...) inside #ifdef DEBUG with dev_dbg() Some parts of the driver use these functions already, so it is only consequent to use the debug function consistently.

* crypto: caam - print debugging hex dumps after unmappingSascha Hauer2019-05-231-10/+11
| | | | | | | | | | | | | | | | For encryption the destination pointer was still mapped, so the hex dump may be wrong. The IV still contained the input IV while printing instead of the output IV as intended. For decryption the destination pointer was still mapped, so the hex dump may be wrong. The IV dump was correct. Do the hex dumps consistenly after the buffers have been unmapped and in case of IV copied to their final destination.

Also, a code path exists which makes decisions based on older (version 3) hardware; a v3 device deosn't support 3DES so remove this check.
