2009-02-1082xx serial, smc: Coding-Style cleanup serial SMC driverHeiko Schocher
Signed-off-by: Heiko Schocher <hs@denx.de>
2009-02-1082xx serial, smc: add configurable SMC Rx buffer lenHeiko Schocher
This patch adds the configuration option CONFIG_SYS_SMC_RXBUFLEN. With this option it is possible to allow the receive buffer for the SMC on 82xx to be greater then 1. In case CONFIG_SYS_SMC_RXBUFLEN == 1 this driver works as the old version. When defining CONFIG_SYS_SMC_RXBUFLEN also CONFIG_SYS_MAXIDLE must be defined to setup the maximum idle timeout for the SMC.

2009-02-10ppc: Move CONFIG_MAX_MEM_MAPPED to common config.hKumar Gala
Moved CONFIG_MAX_MEM_MAPPED to the asm/config.h so its kept consistent between the two current users (lib_ppc/board.c, 44x SPD DDR2). Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Acked-by: Stefan Roese <sr@denx.de>
2009-02-10mpc86xx: Add support to populate addr map based on BATsBecky Bruce
If CONFIG_ADDR_MAP is enabled, update the address map whenever we write a bat. Signed-off-by: Becky Bruce <beckyb@kernel.crashing.org>
2009-02-07pci: Rename PCI_REGION_MEMORY to PCI_REGION_SYS_MEMORY for clarityKumar Gala
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>

2009-02-06Coldfire: M5271: Allow board header file to specify clock multiplierRichard Retanubun
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>
2009-02-06Coldfire: M5271EVB: Remove usage of CONFIG_SYS_FECI2CRichard Retanubun
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>
2009-02-06Coldfire: Fix half-baud UART by adding M5271 to Coldfire v2 core listRichard Retanubun
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>
2009-02-06ppc4xx: Make PCIE support selectableDirk Eibach
On some platforms PCIE support is not required, but would be included because the cpu supports it. To reduce fooprint it is now configurable via CONFIG_PCI_DISABLE_PCIE. Signed-off-by: Dirk Eibach <eibach@gdsys.de> Signed-off-by: Stefan Roese <sr@denx.de>
2009-02-06ppc4xx: Only fixup opb attached UARTsMatthias Fuchs
This patch updates the fdt UART clock fixup code to only touch CPU internal UARTs on 4xx systems. Only these UARTs are definitely clocked by gd->uart_clk. Signed-off-by: Matthias Fuchs <matthias.fuchs@esd-electronics.com> Signed-off-by: Stefan Roese <sr@denx.de>
2009-02-05Blackfin: dynamically update UART speed when initializingMike Frysinger
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. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Robin Getz <rgetz@blackfin.uclinux.org>
2009-02-05Blackfin: add support for fast SPI reads with Boot ROMMike Frysinger
Newer Blackfin boot roms support using the fast SPI read command rather than just the slow one. If the functionality is available, then use it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-02-05Blackfin: check for reserved settings in DDR MMRsMike Frysinger
Some bits of the DDR MMRs should not be set. If they do, bad things may happen (like random failures or hardware destruction). Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-02-05Blackfin: use on-chip syscontrol() rom function when availableMike Frysinger
Newer Blackfin's have an on-chip rom with a syscontrol() function that needs to be used to properly program the memory and voltage settings as it will include (possibly critical) factory tested bias values. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-02-03ADS5121 Add IC Ident Module (IIM) supportMartha Marx
IIM (IC Identification Module) is the fusebox for the mpc5121. Use #define CONFIG_IIM to turn on the clock for this module use #define CONFIG_CMD_FUSE to add fusebox commands. Fusebox commands include the ability to read the status, read the register cache, override the register cache, program the fuses and sense them.

2009-01-28usb.h: use standard __LITTLE_ENDIAN from Linux headersMike Frysinger

2009-01-28Blackfin: allow serial console to be disabledMike Frysinger
Some devices have no UART device pulled out, so allow people to disable the driver completely in favor of other methods (like JTAG-console). Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-01-28Blackfin: support console-over-JTAGMike Frysinger

2009-01-28Blackfin: pass RETX to LinuxMike Frysinger

2009-01-28Blackfin: clarify relocation comment during initMike Frysinger

2009-01-28Blackfin: respect CONFIG_CLKIN_HALFMike Frysinger

2009-01-28Blackfin: use common memcpy routine during initMike Frysinger

2009-01-28Blackfin: overhaul i2c driverMike Frysinger
The current Blackfin i2c driver does not work properly with certain devices due to it breaking up transfers incorrectly. This is a rewrite of the driver and relocates it to the newer place in the source tree. Also remove duplicated I2C speed defines in Blackfin board configs and disable I2C slave address usage since it isn't implemented. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-01-28Blackfin: fix dcache handling when doing dma memcpy'sMike Frysinger
Our dcache invalidate function doesn't just invalidate, it also flushes. So rename the function accordingly and fix the dma_memcpy() function so it doesn't inadvertently corrupt the data destination. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
