Sorry, but I can't comment on this ;)

 From what I see from grepping through the source-tree, there are 
simulator BSP aiming at arm1136*'s:

c/src/lib/libbsp/arm/gdbarmsim/make/custom/arm1136jfs.cfg:#  Config file 
for GDB ARM Simulator as arm1136jf-s (FPU)
c/src/lib/libbsp/arm/gdbarmsim/make/custom/arm1136jfs.cfg:RTEMS_CPU_MODEL=arm1136
c/src/lib/libbsp/arm/gdbarmsim/make/custom/arm1136jfs.cfg:CPU_CFLAGS = 
-mcpu=arm1136jf-s
c/src/lib/libbsp/arm/gdbarmsim/make/custom/arm1136js.cfg:#  Config file 
for GDB ARM Simulator as arm1136j-s (no FPU)
c/src/lib/libbsp/arm/gdbarmsim/make/custom/arm1136js.cfg:RTEMS_CPU_MODEL=arm1136
c/src/lib/libbsp/arm/gdbarmsim/make/custom/arm1136js.cfg:CPU_CFLAGS = 
-mcpu=arm1136j-s
c/src/lib/libbsp/arm/gdbarmsim/make/custom/armcortexa9.cfg:RTEMS_CPU_MODEL=arm1136

but no real BSPs.

In cpukit, ARMv6 seems to be aliased to ARMv4.
