+# pma.yaml
+# Describes RISC-V Physical Memory Attributes (PMA) for a platform.
+# See RISC-V Privileged Architectures specification for more details on PMA.
+
+# Required fields:
+# name: A string name for the PMA region.
+# lo: The lower bound of the PMA region, as a hexadecimal string.
+# hi: The upper bound of the PMA region, as a hexadecimal string.
+# attributes: A dictionary of PMA attributes for the region.
+# The following attributes are required:
+#   size: A list of supported access sizes (in bytes) for the region.
+#   read: A boolean indicating if the region is readable.
+#   write: A boolean indicating if the region is writable.
+#   execute: A boolean indicating if the region is executable.
+#   cacheable: A boolean indicating if the region is cacheable.
+#   coherent: A boolean indicating if the region is coherent.
+#             Writes by one agent to an address in the region are eventually visible to other coherent agents in the system.
+# The following attributes are optional and have default values if not specified:
+#   idempotent_read: A boolean indicating if reads from the region are idempotent (default: same as read)
+#   idempotent_write: A boolean indicating if writes to the region are idempotent (default: same as write)
+#   hptw_read: A boolean indicating if the region supports host page table walks (default: same as read)
+#   hptw_write: A boolean indicating if the region supports host page table walks (default: same as write)
+#   misaligned_scalar: A boolean indicating if the region supports misaligned scalar accesses (default: false)
+#   misaligned_vector: A boolean indicating if the region supports misaligned vector accesses (default: false)
+#   cboz: A boolean indicating if the region supports cache block zeroing (default: false)
+#   ordering: The memory ordering model for the region, as a string (default: "ioweak")
+#       Options: "MainMem", "IORelaxed", "IOStrongCh0", "IOStrongCh1", "Other"
+#   amo: The type of atomic memory operations supported by the region, as a string (default: "AMONone")
+#       Options: "AMONone", "AMOSwap", "AMOLogical", "AMOArithmetic", "AMOCASW", "AMOCASD", "AMOCASQ"
+#   reserve: The type of reservation granularity for the region, as a string (default: "RsrvNone")
+#       Options: "RsrvNone", "RsrvNonEventual", "RsrvEventual"
+#   misaligned_atomicity_granule: The granularity (in bytes) for atomic accesses to the region that support misaligned atomics (default: 0, meaning misaligned AMOs are not supported)
