* pci: Rename PCI_REGION_MEMORY to PCI_REGION_SYS_MEMORY for clarityKumar Gala2009-02-07-13/+13
| | | | | | | | | | The PCI_REGION_MEMORY and PCI_REGION_MEM are a bit to similar and can be confusing when reading the code. Rename PCI_REGION_MEMORY to PCI_REGION_SYS_MEMORY to clarify its used for system memory mapping purposes. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| * Coldfire: M5271: Allow board header file to specify clock multiplierRichard Retanubun2009-02-06-1/+6
| | | | | | | | | | | | | | | | | | M5271 dynamic clock multiplier. It is currently fixed at 100MHz. Allow the board header file to set their own multiplier and divider. Added the #define for the multiplier and divider to the cpu header file. Signed-off-by: Richard Retanubun <RichardRetanubun@RuggedCom.com>
| * Coldfire: M5271EVB: Remove usage of CONFIG_SYS_FECI2CRichard Retanubun2009-02-06-1/+2
| | | | | | | | | | | | | | Discontinue the use of CONFIG_SYS_FECI2C (only used by M5271EVB). Use read-modify-write to activate the FEC pins without disabling I2C. Signed-off-by: Richard Retanubun <RichardRetanubun@RuggedCom.com>
| * Coldfire: Fix half-baud UART by adding M5271 to Coldfire v2 core listRichard Retanubun2009-02-06-1/+2
| | | | | | | | | | | | | | | | | | Added the CONFIG_M5271 to the list of Coldfire V2 processor. This was causing the bus clock (not CPU clock) to be declared twice as fast as it actually is. This causes UARTS to operate at half the specified baudrate. Signed-off-by: Richard Retanubun <RichardRetanubun@RuggedCom.com>

| * | Blackfin: dynamically update UART speed when initializingMike Frysinger2009-02-05-91/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, booting over the UART required the baud rate to be known ahead of time. Using a bit of tricky simple math, we can calculate the new board rate based on the old divisors.

| | | | | | | | | | | | | | | | | | | | | | | | | | | On some platforms PCIE support is not required, but would be included because the cpu supports it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change is needed for mgcoge because it uses two ethernet drivers. Add a check for the presence of the PIGGY board on mgcoge. Without this board networking cannot work and the initialization must be aborted. Only allocate rtx once to prevent DPRAM exhaustion.
