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: set default voltage levels for BF538/BF539 partsMike Frysinger
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.

2009-02-02Blackfin: 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>
2009-02-02Blackfin: enable --gc-sectionsMike Frysinger
Start building all Blackfin boards with -ffunction-sections/-fdata-sections and linking with --gc-sections. 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: 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: 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.
