[PATCH v2 0/7] ARM64: crypto: add Crypto Extensions accelerated SHA implementation

[Ahmad Fatoum]

This shaves 400ms of a FIT image boot that uses sha256 as digest for
the images referenced by the selected configuration:

  barebox at imx8mn-old:/ time bootm -d kernel-a
  Dryrun. Aborted.
  time: 998ms

  barebox at imx8mn-new:/ time bootm -d kernel-a
  Dryrun. Aborted.
  time: 601ms

We also use SHA256 to verify barebox proper when in high assurance boot,
but that still uses the software implementation.

v1 -> v2:
  - use dedicated CONFIG_ symbols for SHA224/SHA256 selftest (Sascha)
  - check against CONFIG_ symbols for generic algorithm
  - remove #define DEBUG in selftest
  - fix oversight in new <linux/linkage.h> __ALIGN definition,
    which broke build on x86 and PowerPC
  - 

Ahmad Fatoum (7):
  crypto: digest: match driver name if no algo name matches
  test: self: add digest test
  include: sync <linux/linkage.h> with Linux
  ARM: asm: implement CPU_BE/CPU_LE
  ARM: asm: import Linux adr_l/ldr_l assembler.h definitions
  crypto: sha: reorder struct sha*_state into Linux order
  ARM64: crypto: add Crypto Extensions accelerated SHA implementation
