Updates to AXI DMA random test #829

anjpar · 2025-03-17T16:57:26Z

Enables random delay and random reset injection
Enables auto-read and auto-write FIFO for large transfers
Pre-fills AXI SRAM with random data that can be used for large transfers where the source is SRAM
Weights for reset injection is 2:1 (reset : no-reset) in randomizer class
Prints status every 8K dwords for large transfers (>32K)

* added zeroize/scanmode injection test * updated submodule * updated regression tests * released slot #8 after mldsa seed injection * included debug/scan mode * updated ABR submodule * removed hardcoded time

* added ECDH to ecc uvmf * fixed aes keyvault endianness * added ecdh smoke test * added error conditions for keygen and ecdh --------- Co-authored-by: Michael Norris <michnorris@microsoft.com>

* mbox tap missing implementation * updates to tap mailbox * updating tap mailbox functionality jtag test for tap mailbox flow * removing extra files * fixing tap mailbox mode now tap can initialize the mailbox request and receive response from uc * adding coverpoint for uc -> tap mbox response * missed reset * fixing rdc in dma block usin the correct clock * fixed bug where lock wouldn't clear after tap released the lock updated jtag tap mbox test to include back to back tap initiated requests * rolling back changes to force reset * removing change ported from another branch that needs additional changes * adding control bit to unlock mailbox for tap access fixed write permissions given to tap on dbg service response * updating integration spec with details about tap mailbox flow from the tap side. updating permissions for tap access to straps

* Fix physical_rng in file-lists, regenerate * Update HW_REV_ID, hw_config smoke test
