4a701c11e4 mem-ruby: Fix maskLowOrderBits
The function was wrong when number = 63. Also, use the more reliable
src/base/bitfield.hh's mbits when posible.

maskLowOrderBits has only been kept because SLICC does not accept
a templated function.

a5408244d1 mem-ruby: Remove shiftLowOrderBits
There is no need to encapsulate a shift operation.

7ccf70a121 mem-ruby: Remove maskHighOrderBits
Function was not being used. If needed, src/base/bitfield.hh's
mbits can be used instead:

maskHighOrderBits(addr, pos) == mbits<Addr>(addr, 64-pos, 0)

0219c49bdf mem-ruby: Remove bitRemove
bitRemove is not being used anywhere. If needed, can be used
as src/base/bitfield.hh's bits:

bitRemove(addr, small, big) ==
    ((bits<Addr>(addr, 63, big + 1) << small) |
    bits<Addr>(addr, small, 0))

96c999fe88 ruby: print addresses in hex
Changeset 4872dbdea907 replaced Address by Addr, but did not make changes to
print statements.  So the addresses which were being printed in hex earlier
along with their line address, were now being printed in decimals.  This patch
adds a function printAddress(Addr) that can be used to print the address in hex
along with the lines address.  This function has been put to use in some of the
places.  At other places, change has been made to print just the address in
hex.

b6b972da99 ruby: rename System.{hh,cc} to RubySystem.{hh,cc}
The eventual aim of this change is to pass RubySystem pointers through to
objects generated from the SLICC protocol code.

Because some of these objects need to dereference their RubySystem pointers,
they need access to the System.hh header file.

In src/mem/ruby/SConscript, the MakeInclude function creates single-line header
files in the build directory that do nothing except include the corresponding
header file from the source tree.

However, SLICC also generates a list of header files from its symbol table, and
writes it to mem/protocol/Types.hh in the build directory. This code assumes
that the header file name is the same as the class name.

The end result of this is the many of the generated slicc files try to include
RubySystem.hh, when the file they really need is System.hh. The path of least
resistence is just to rename System.hh to RubySystem.hh.

--HG--
rename : src/mem/ruby/system/System.cc => src/mem/ruby/system/RubySystem.cc
rename : src/mem/ruby/system/System.hh => src/mem/ruby/system/RubySystem.hh

91a84c5b3c ruby: replace Address by Addr
This patch eliminates the type Address defined by the ruby memory system.
This memory system would now use the type Addr that is in use by the
rest of the system.

df973abef3 mem: Dynamically determine page bytes in memory components
This patch takes a step towards an ISA-agnostic memory
system by enabling the components to establish the page size after
instantiation. The swap operation in the memory is now also allowing
any granularity to avoid depending on the IntReg of the ISA.

e1ac962939 arch: Cleanup unused ISA traits constants
This patch prunes unused values, and also unifies how the values are
defined (not using an enum for ALPHA), aligning the use of int vs Addr
etc.

The patch also removes the duplication of PageBytes/PageShift and
VMPageSize/LogVMPageSize. For all ISAs the two pairs had identical
values and the latter has been removed.

2cbe7c705b ruby: remove typedef of Index as int64
The Index type defined as typedef int64 does not really provide any help
since in most places we use primitive types instead of Index.  Also, the name
Index is very generic that it does not merit being used as a typename.

6bf7153104 Ruby: Make Address.hh independent of RubySystem
This patch changes Address.hh so that it is not dependent on RubySystem.
This dependence seems unecessary. All those functions that depend on
RubySystem have been moved to Address.cc file.

f1c3f3044b ruby: get "using namespace" out of headers
In addition to obvious changes, this required a slight change to the slicc
grammar to allow types with :: in them.  Otherwise slicc barfs on std::string
which we need for the headers that slicc generates.

24da30e317 ruby: Make ruby #includes use full paths to the files they're including.
This basically means changing all #include statements and changing
autogenerated code so that it generates the correct paths.  Because
slicc generates #includes, I had to hard code the include paths to
mem/protocol.

2f30950143 ruby: Import ruby and slicc from GEMS
