| * | mpc512x: add multi serial PSC supportAnatolij Gustschin2010-04-24-81/+293
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Extend mpc512x serial driver to support multiple PSC ports. Subsequent patches for PDM360NG board support make use of this functionality by defining CONFIG_SERIAL_MULTI in the board config file. Additionally the used PSC devices are specified by defining e.g. CONFIG_SYS_PSC1, CONFIG_SYS_PSC4 and CONFIG_SYS_PSC6. Support for PSC devices other than 1, 3, 4 and 6 is not added by this patch because these aren't used currently. In the future it can be easily added using DECLARE_PSC_SERIAL_FUNCTIONS(N) and INIT_PSC_SERIAL_STRUCTURE(N) macros in cpu/mpc512x/serial.c. Additionally you have to add code for registering added devices in serial_initialize() in common/serial.c. Signed-off-by: Anatolij Gustschin <agust@denx.de>

| * | ppc: Split MPC83xx SERDES code from MPC85xx/MPC86xx/QorIQKumar Gala2010-04-26-1/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | The MPC83xx SERDES control is different from the other FSL PPC chips. For now lets split it out so we can standardize on interfaces for determining of a device on SERDES is configured.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When DDR is in synchronous mode, the existing code assigns sysclk frequency to DDR frequency. It should be synchronous with the platform frequency. CPU frequency is based on platform frequency in synchronous mode. Also fix: * Fixes the bit mask for DDR_SYNC (RCWSR5[184]) * Corrects the detection of synchronous mode.

* | | serial: struct serial_device: add uninit() entry for driversAnatolij Gustschin2010-04-24-0/+6
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | Subsequent patch extends mpc512x serial driver to support multiple PSC ports. The driver will provide an uninit() function to stop the serial controller and to disable the controller's clock. Adding uninit() entry to struct serial_device allows disabling the serial controller after usage of a stdio serial device. This patch adds uninit() entry to the struct serial_device and fixes initialization of this structure in the code accordingly. Signed-off-by: Anatolij Gustschin <agust@denx.de>

* Move arch/ppc to arch/powerpcStefan Roese2010-04-21-0/+105169
As discussed on the list, move "arch/ppc" to "arch/powerpc" to better match the Linux directory structure. Please note that this patch also changes the "ppc" target in MAKEALL to "powerpc" to match this new infrastructure. But "ppc" is kept as an alias for now, to not break compatibility with scripts using this name.
