• bda63586b   firmware: Sigma: Fix endianess issues ... Browse Code »

  Currently the SigmaDSP firmware loader only works correctly on little-endian
  systems. Fix this by using the proper endianess conversion functions.

• 4f718a29f   firmware: Sigma: Prevent out of bounds memory access ... Browse Code »

  The SigmaDSP firmware loader currently does not perform enough boundary size
  checks when processing the firmware. As a result it is possible that a
  malformed firmware can cause an out of bounds memory access.

  This patch adds checks which ensure that both the action header and the payload
  are completely inside the firmware data boundaries before processing them.

• e359dc24d   sigma-firmware: loader for Analog Devices' SigmaStudio ... Browse Code »

  Analog Devices' SigmaStudio can produce firmware blobs for devices with
  these DSPs embedded (like some audio codecs). Allow these device drivers
  to easily parse and load them.
