2021-06-03crypto: octeontx2 - add support to map LMTST region for CN10KSrujana Challa
On CN10K platform transmit/receive buffer alloc and free from/to hardware had changed to support burst operation. Whereas pervious silicon's only support single buffer free at a time. To Support the same firmware allocates a DRAM region for each PF/VF for storing LMTLINES. These LMTLINES are used to send CPT commands to HW. PF/VF LMTST region is accessed via BAR4. PFs LMTST region is followed by its VFs mbox memory. The size of region varies from 2KB to 256KB based on number of LMTLINES configured. This patch adds support for mapping of PF/VF LMTST region.

2021-06-03crypto: octeontx2 - Add mailbox support for CN10KSrujana Challa
Mailbox region configuration has some changes on CN10K platform from OcteonTX2(CN9XX) platform. On CN10K platform: The DRAM region allocated to PF is enumerated as PF BAR4 memory. PF BAR4 contains AF-PF mbox region followed by its VFs mbox region. AF-PF mbox region base address is configured at RVU_AF_PFX_BAR4_ADDR PF-VF mailbox base address is configured at RVU_PF(x)_VF_MBOX_ADDR = RVU_AF_PF()_BAR4_ADDR+64KB. PF access its mbox region via BAR4, whereas VF accesses PF-VF DRAM mailboxes via BAR2 indirect access. On CN9XX platform: Mailbox region in DRAM is divided into two parts AF-PF mbox region and PF-VF mbox region i.e all PFs mbox region is contiguous similarly all VFs. The base address of the AF-PF mbox region is configured at RVU_AF_PF_BAR4_ADDR. AF-PF1 mbox address can be calculated as RVU_AF_PF_BAR4_ADDR * mbox size. This patch changes mbox initialization to support both CN9XX and CN10K platform. This patch also removes platform specific name from the PF/VF driver name to make it appropriate for all supported platforms.

2021-02-10crypto: octeontx2 - fix -Wpointer-bool-conversion warningArnd Bergmann
When CONFIG_CPUMASK_OFFSTACK is disabled, clang reports a warning about a bogus condition: drivers/crypto/marvell/octeontx2/otx2_cptlf.c:334:21: error: address of array 'lfs->lf[slot].affinity_mask' will always evaluate to 'true' [-Werror,-Wpointer-bool-conversion] if (lfs->lf[slot].affinity_mask) ~~ ~~~~~~~~~~~~~~^~~~~~~~~~~~~ In this configuration, the free_cpumask_var() function does nothing, so the condition could be skipped. When the option is enabled, there is no warning, but the check is also redundant because free_cpumask_var() falls back to kfree(), which is documented as ignoring NULL pointers. Remove the check to avoid the warning.

2021-01-22crypto: octeontx2 - register with linux crypto frameworkSrujana Challa
CPT offload module utilises the linux crypto framework to offload crypto processing. This patch registers supported algorithms by calling registration functions provided by the kernel crypto API. The module currently supports: - AES block cipher in CBC,ECB and XTS mode. - 3DES block cipher in CBC and ECB mode. - AEAD algorithms. authenc(hmac(sha1),cbc(aes)), authenc(hmac(sha256),cbc(aes)), authenc(hmac(sha384),cbc(aes)), authenc(hmac(sha512),cbc(aes)), authenc(hmac(sha1),ecb(cipher_null)), authenc(hmac(sha256),ecb(cipher_null)), authenc(hmac(sha384),ecb(cipher_null)), authenc(hmac(sha512),ecb(cipher_null)), rfc4106(gcm(aes)).

2021-01-22crypto: octeontx2 - enable SR-IOV and mailbox communication with VFSrujana Challa
Adds 'sriov_configure' to enable/disable virtual functions (VFs). Also Initializes VF<=>PF mailbox IRQs, register handlers for processing these mailbox messages. Admin function (AF) handles resource allocation and configuration for PFs and their VFs. PFs request the AF directly, via mailboxes. Unlike PFs, VFs cannot send a mailbox request directly. A VF sends mailbox messages to its parent PF, with which it shares a mailbox region. The PF then forwards these messages to the AF. After handling the request, the AF sends a response back to the VF, through the PF. This patch adds support for this 'VF <=> PF <=> AF' mailbox communication.
