2023-10-10docs: move powerpc under archCosta Shulyupin
and fix all in-tree references. Architecture-specific documentation is being moved into Documentation/arch/ as a way of cleaning up the top-level documentation directory and making the docs hierarchy more closely match the source hierarchy.

2020-09-15powerpc/watchpoint/ptrace: Introduce PPC_DEBUG_FEATURE_DATA_BP_ARCH_31Ravi Bangoria
PPC_DEBUG_FEATURE_DATA_BP_ARCH_31 can be used to determine whether we are running on an ISA 3.1 compliant machine. Which is needed to determine DAR behaviour, 512 byte boundary limit etc. This was requested by Pedro Miraglia Franco de Carvalho for extending watchpoint features in gdb. Note that availability of 2nd DAWR is independent of this flag and should be checked using ppc_debug_info->num_data_bps.

2019-07-17docs: powerpc: convert docs to ReST and rename to *.rstMauro Carvalho Chehab
Convert docs to ReST and add them to the arch-specific book. The conversion here was trivial, as almost every file there was already using an elegant format close to ReST standard. The changes were mostly to mark literal blocks and add a few missing section title identifiers. One note with regards to "--": on Sphinx, this can't be used to identify a list, as it will format it badly. This can be used, however, to identify a long hyphen - and "---" is an even longer one. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings.
