This is not entirely separate address space, therefore it does not have
a separate name. The address space name is still TCSR_MUTEX which
consists of actual MUTEX regs, halt regs and bunch of others. The second
one 0x7a0000 (where label I renamed to tcsr_2) is called TCSR_REGS.
This applies to other patches as well, so maybe you prefer to have
labels matching the spec? The first would be tcsr_mutex_regs, although
it is not entirely correct, because it does not include now the TCSR
mutex regs...
Best regards,
Krzysztof
