			This patch adds support for hardware syncpoint bases. This creates a simple mechanism to stall the command FIFO until an operation is completed.

 | |
|   *     <x>_r(void) : Returns the offset for register <x>.

 | |
|   *     <x>_w(void) : Returns the word offset for word (4 byte) element <x>.
 | |
|   *
 | |
|   *     <x>_<y>_s(void) : Returns size of field <y> of register <x> in bits.
 | |
|   *
 | |
|   *     <x>_<y>_f(u32 v) : Returns a value based on 'v' which has been shifted
 | |
|   *         and masked to place it at field <y> of register <x>.  This value
 | |
|   *         can be |'d with others to produce a full register value for
 | |
|   *         register <x>.

|   *
 | |
|   *     <x>_<y>_m(void) : Returns a mask for field <y> of register <x>.  This
 | |
|   *         value can be ~'d and then &'d to clear the value of field <y> for
 | |
|   *         register <x>.
 | |

|   *     <x>_<y>_<z>_f(void) : Returns the constant value <z> after being shifted

|   *         with others to produce a full register value for <x>.
 | |
|   *
 | |
|   *     <x>_<y>_v(u32 r) : Returns the value of field <y> from a full register
 | |
|   *         <x> value 'r' after being shifted to place its LSB at bit 0.
 | |
|   *         This value is suitable for direct comparison with other unshifted
 | |
|   *         values appropriate for use in field <y> of register <x>.

 | |
|   *         comparison with unshifted values appropriate for use in field <y>
