[PATCHv4 0/4] crypto: inside-secure - broaden driver scope

[Pascal van Leeuwen <pascalvanl@gmail.com>]

This is a first baby step towards making the inside-secure crypto driver
more broadly useful. The current driver only works for Marvell Armada HW
and requires proprietary firmware, only available under NDA from Marvell,
to be installed. This patch set allows the driver to be used with other
hardware and removes the dependence on that proprietary firmware.

changes since v1:
- changed dev_info's into dev_dbg to reduce normal verbosity
- terminate all message strings with \n
- use priv->version field strictly to enumerate device context
- fixed some code & comment style issues
- removed EIP97/197 references from messages
- use #if(IS_ENABLED(CONFIG_PCI)) to remove all PCI related code
- use #if(IS_ENABLED(CONFIG_OF)) to remove all device tree related code
- do not inline the minifw but read it from /lib/firmware instead

changes since v2:
- split off removal of alg to engine mapping code into separate patch
- replaced some constants with nice defines
- added missing \n to some error messages
- removed some redundant parenthesis
- aligned some #if's properly
- added some comments to clarify code
- report error on FW load for unknown HW instead of loading EIP197B FW
- use readl_relaxed() instead of readl() + cpu_relax() in polling loop
- merged patch "fix null ptr dereference on rmmod for macchiatobin" here
- merged patch "removed unused struct entry"

changes since v3:
- reverted comment style from generic back to network
- changed prefix "crypto_is_" to "safexcel_" for consistency

Pascal van Leeuwen (4):
  crypto: inside-secure - make driver selectable for non-Marvell
    hardware
  crypto: inside-secure - Remove redundant algo to engine mapping code
  crypto: inside-secure - add support for PCI based FPGA development
    board
  crypto: inside-secure - add support for using the EIP197 without
    vendor firmware
