No, I have no any related hardware for it.

For this issue, I referenced arch/blackfin/Makefile for BF_REL:

  [root@...alhost linux-next]# echo "" | /upstream/release-blackfin/bin/bfin-gchen-elf-gcc -dD -mcpu=bf533-0.6 -E  - | grep __SILICON_REVISION__
  #define __SILICON_REVISION__ 0x0006
  [root@...alhost linux-next]# echo "" | /upstream/release-blackfin/bin/bfin-gchen-elf-gcc -dD -mcpu=bf533-0.5 -E  - | grep __SILICON_REVISION__
  #define __SILICON_REVISION__ 0x0005
  [root@...alhost linux-next]# echo "" | /upstream/release-blackfin/bin/bfin-gchen-elf-gcc -dD -mcpu=bf533-0.4 -E  - | grep __SILICON_REVISION__

  [root@...alhost linux-next]# echo "" | /upstream/release-blackfin/bin/bfin-gchen-elf-gcc -dD -mcpu=bf533-0.3 -E  - | grep __SILICON_REVISION__
