# System register metadata
# Each System register is described by a Sysreg block:
# Sysreg <name> <op0> <op1> <crn> <crm> <op2>
# <field>
# ...
# EndSysreg
# Within a Sysreg block, each field can be described as one of:
# Res0 <msb>[:<lsb>]
# Res1 <msb>[:<lsb>]
# Field <msb>[:<lsb>] <name>
# Enum <msb>[:<lsb>] <name>
# <enumval> <enumname>
# ...
# EndEnum
# Alternatively if multiple registers share the same layout then
# a SysregFields block can be used to describe the shared layout
# SysregFields <fieldsname>
# <field>
# ...
# EndSysregFields
# and referenced from within the Sysreg:
# Sysreg <name> <op0> <op1> <crn> <crm> <op2>
# Fields <fieldsname>
# EndSysreg
# For ID registers we adopt a few conventions for translating the
# language in the ARM into defines:
#
# NI - Not implemented
# IMP - Implemented
#
# In general it is recommended that new enumeration items be named for the
# feature that introduces them (eg, FEAT_LS64_ACCDATA introduces enumeration
# item ACCDATA) though it may be more taseful to do something else.
