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>
2009-02-02Blackfin: rewrite cache handling functionsMike Frysinger
Take the cache flush functions from the kernel as they use hardware loops in order to get optimal performance. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-01-28usb.h: use standard __LITTLE_ENDIAN from Linux headersMike Frysinger
Rather than forcing people to define a custom "LITTLEENDIAN", just use the __LITTLE_ENDIAN one from the Linux byteorder headers that every arch is already setting up. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Remy Bohmer <linux@bohmer.net>

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
The Blackfin JTAG has the ability to pass data via a back-channel without halting the processor. Utilize that channel to emulate a console. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-01-28Blackfin: handle new anomalies with resetMike Frysinger
Workaround fun new anomalies related to software reset of the processor. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-01-28Blackfin: pass RETX to LinuxMike Frysinger
Make sure we save the value of RETX at power on and then pass it on to the kernel so that it can nicely debug a "double-fault-caused-a-reset" crash. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-01-28Blackfin: clarify relocation comment during initMike Frysinger
People often ask questions about the init process and when things go from flash to relocated base, so clarify the comments a bit. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-01-28Blackfin: just set SP register directly during initMike Frysinger
No need to set the SP register indirectly to the configured value when it can be set directly. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-01-28Blackfin: respect CONFIG_CLKIN_HALFMike Frysinger
As pointed out by Ivan Koryakovskiy, the initialization code was not actually respecting the CONFIG_CLKIN_HALF option when configuring the PLL_CTL register. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-01-28Blackfin: use common memcpy routine during initMike Frysinger
Rather than using a local custom memcpy function, just call the existing optimized Blackfin version. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
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>

2009-01-27MIPS: Add flush_dcache_range() and invalidate_dcache_range()Stefan Roese
This patch adds flush_/invalidate_dcache_range() to the MIPS architecture. Those functions are needed for the upcoming dcache support for the USB EHCI driver. I chose this API because those cache handling functions are already present in the PPC architecture.

2009-01-24mgcoge make ether_scc.c work with CONFIG_NET_MULTIGary Jennejohn
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. Initialize ether_scc.c and the keymile-specific HDLC driver (to be added soon) in eth.c. Signed-off-by: Gary Jennejohn <garyj@denx.de> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>

The NMDK8815 board is distributed by ST Microelectornics. Other (proprietary) code must be run to unlock the CPU before U-Boot runs. doc/README.nmdk8815 outlines the boot sequence.

CONFIG_SC520 is now used for conditional compile Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
2009-01-24Added MMCR reset functionalityGraeme Russ
Reset function specific to AMD SC520 microcontroller - Is more of a 'hard reset' that the triple fault. Requires CONFIG_SYS_RESET_SC520 to be defined in config I would have liked to add this to a new file (cpu/i386/sc520/reset.c) but ld requires that a object file in a library arhive MUST contain at least one function which does not override a weak function (and is called from outside the object file) in order for that object file to be extracted from the archive. This would be the only function on the new file, and hence, will never get linked in. Signed-off-by: Graeme Russ <graeme.russ@gmail.com>
2009-01-24Moved generic (triple fault) reset codeGraeme Russ
Moved from interrupts.c to cpu.c and made into a weak function to allow vendor specific override Vendor specific CPU reset (like the AMD SC520 MMCR reset) can now be added to the vendor specific code without the need to remember to #undef usage of the generic method and if you forget to include your custom reset method, you will always get the default.
