2014-12-11capwap: add capwap supportPan Jiafei
CAPWAP stands for Control and Provisioning of Wireless Access Points. CAPWAP is a standard, interoperable protocol that enables a controller to manage a collection of wireless access points. There are three drivers in Kernel Space: CAPWAP Domain driver, CAPWAP Bridge driver and CAPWAP Tunnel driver. CAPWAP Domain Driver implements configuration for CAPWAP Domain, including PCD configuration and FQs setup. User must configure and initialize CAPWAP domain before CAPWAP Tunnel and CAPWAP Bridge works. CAPWAP Tunnel Driver is a misc device driver, which registers four misc devices for four CAPWAP tunnels: fsl-capwap-ctrl-dtls, fsl-capwap-ctl-n-dtls, fsl-capwap-data-dtls, fsl-capwap-data-n-dtls. The misc device provides file-operation to transmit/receive DTLS/non-DTLS packets. For example, read from the device fsl-capwap-ctrl-dtls can receive DTLS control packet; Write to the device fsl-capwap-ctrl-dtls can transmit DTLS control packet. The CAPWAP Bridge Driver is also a misc device driver; it can bridge packets between PCIe NIC and CAPWAP data tunnels. To support capwap drivers, there should be a shared ethernet port in dts file to use as CAPWAP Ethernet port.

CAAM. CAAM's memory is broken into following address blocks: Block Included Registers 7 QI registers Size of the above stated block varies in various platforms. The block size can be 4K or 64K. The block size can be dynamically determined by reading CTPR register in CAAM. This patch fixes the issues related to the dynamic initialization of the QI block address based on the value read from this register.

2014-12-11crypto: 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.

2014-05-13crypto: caam/qi - fix handling of create_caam_req_fq(...) errorAlex Porosanu
When create_caam_req_fq(...) returns an error, it does so by using the ERR_PTR macro, due to its return type. Thus the return of this function needs to be checked by using the corresponding IS_ERR_* class of macros, and not by a "if(!ret)" construct. This patch adds the necessary macro calls in all the locations where create_caam_req_fq(...) is called.

2014-04-08crypto: caam - fix RNG4 instantiationAlex Porosanu
The RNG4 block in CAAM needs to be 'seeded' first before being used for generating pseudo-random data. The 'seeding' is done by getting entropy from the TRNG ring oscillator. The RTFRQMAX register controls the maximum allowable number of samples that can be aquired during an entropy sample. Depending on the clock at which the RNG4 block (and for that matter the SEC block) runs, it's possible that a hard-coded value for the maximum frequency is inadequate, i.e. more samples than needed are taken. This is an error, and thus the RNG4 block doesn't get initialized. The patch attempts to alleviate this issue by trying with progressivly larger frequencies, until the number of samples is adequate. This patch also fixes how a descriptor is deemed as being finished: instead of checking the VALID field in the DECO debug register, it makes sure that the DECO is idle, by checking the DECO state field of the said register.
