[PATCH v4 0/6] crypto/fsl: add RNG support

[Michael Walle]

First, improve the compatibility on newer Era CAAMs. These introduced new
version registers. Secondly, add RNG support for the CAAM. This way we get
random number generator support for EFI for free and KASLR will work with
ARM64 kernels booted with bootefi.

Changes since v3:
 - use private data instead of platform data in RNG driver, thanks
   Heinrich
 - align end address of any invalidate/flush_dcache_range(), thanks
   Heinrich
 - because we do the alignment ourself, use memalign() again (instead
   of malloc_cache_aligned())

Changes since v2:
 - fix descriptor size of the deinstantiate descriptor
 - use malloc_cache_aligned() instead of memalign(ARCH_DMA_MINALIGN..)
 - don't check the RDSTA_PR() bit
 - fix memcpy() length
 - flush the dcache where the rng job description resides

Changes since v1:
 - instantiate RNG with prediction resistance
 - add annotation for caam_get_era()
 - fix all prints to match u-boots status lines
 - remove superfluous #ifdef CONFIG_DM_RNG
 - changed kconfig help text

Michael Walle (6):
  crypto/fsl: make SEC%u status line consistent
  crypto/fsl: export caam_get_era()
  crypto/fsl: support newer SEC modules
  crypto/fsl: don't regenerate secure keys
  crypto/fsl: instantiate the RNG with prediciton resistance
  crypto/fsl: add RNG support
