-GCC 4.4.x looks to be adding support for generating out-of-line register
-saves/restores based on:
-
-http://gcc.gnu.org/ml/gcc-patches/2008-04/msg01678.html
-
-This breaks the kernel build as we'd have to link with libgcc to get the
-implementation of the register save/restores.
-
-To workaround this issue, we just stole the save/restore code from gcc
-and simplified it down for our needs (integer only). We only do this if
-PPC32 as gcc makes believe the linker on ppc64 will deal with this and
-only if CONFIG_CC_OPTIMIZE_FOR_SIZE is set (thus -Os).
-
-Signed-off-by: Kumar Gala <[EMAIL PROTECTED]>

-
-If someone using cutting edge toolchains for ppc64 could test and make
-sure if we enable CONFIG_CC_OPTIMIZE_FOR_SIZE things work that would be
-nice.

++ The TDM driver is for UCC based TDM devices for example, TDM device on
++ MPC832x RDB. Select it to run PowerVoIP on MPC832x RDB board.
++ The TDM driver can interface with SLIC kind of devices to transmit
++ and receive TDM samples. The TDM driver receives Time Division
++ multiplexed samples(for different channels) from the SLIC device,
++ demutiplexes them and sends them to the upper layers. At the transmit
++ end the TDM drivers receives samples for different channels, it
++ multiplexes them and sends them to the SLIC device.
