2011-09-04armv7: cache: remove flush on un-aligned invalidateAneesh V
Remove the flush of boundary cache-lines done as part of invalidate on a non cache-line boundary aligned buffer Also, print a warning when this situation is recognized. Signed-off-by: Aneesh V <aneesh@ti.com>
2011-09-04armv7: stronger barrier for cache-maintenance operationsAneesh V
set-way operations need a DSB after them to ensure the operation is complete. DMB may not be enough. Use DSB after all operations instead of DMB. Signed-off-by: Aneesh V <aneesh@ti.com>

2011-09-04arm: do not force d-cache enable on all boardsAneesh V
c2dd0d45540397704de9b13287417d21049d34c6 added dcache_enable() to board_init_r(). This enables d-cache for all ARM boards. As a result some of the arm boards that are not cache-ready are broken. Revert this change and allow platform code to take the decision on d-cache enabling. Also add some documentation for cache usage in ARM. Signed-off-by: Aneesh V <aneesh@ti.com>
2011-09-04i2c:gpio:s5p: I2C GPIO Software implementation (via soft_i2c)Łukasz Majewski

2011-09-04MX: MX35 / MX5: uniform clock command with powerpcStefano Babic
There was already a command to show the processor clocks for PowerPC (clocks). For i.MX, the "clockinfo" command was introduce. The patch sets the same command name used on PowerPC. A nasty and not needed newline is also dropped in the help for the command. Signed-off-by: Stefano Babic <sbabic@denx.de>
2011-09-04ARM: MX51: PLL errata workaroundDavid Jander
This is a port of the official PLL errata workaround from Freescale to mainline u-boot. The PLL's in the i.MX51 processor can go out of lock due to a metastable condition in an analog flip-flop when used at high frequencies. This workaround implements an undocumented feature in the PLL (dither mode), which causes the effect of this failure to be much lower (in terms of frequency deviation), avoiding system failure, or at least decreasing the likelihood of system failure.

2011-09-03gpio:samsung s5p_ suffix add for GPIO functionsŁukasz Majewski
This change is driven by need of general gpio_* functions, which as their parameter are accepting the GPIO pin number, NOT block and pin. This makes the code alike to omap, and allows for using more generic frameworks (e.g. software I2C).

2011-09-03integrator: convert to new build systemLinus Walleij
This deletes the integrator split_by_variant.sh script and defines a number of unique board types for the core modules that are meaningful to support for the Integrator AP/CP, i.e. the ones that did not just say "unsupported core module" in split_by_variant.sh. If more core modules need to be supported they are easy to add. We delete all the old cruft in Makefile and MAKEALL that was working around the old way of building boards. We create a unique config file per board to satisfy the build system, but they are just oneliners that include the existing integratorap.h and integratorcp.h configs.

2011-08-03omap4: automatic sdram detectionAneesh V
Identify SDRAM devices connected to EMIF automatically: LPDDR2 devices have some Mode Registers that provide details about the device such as the type, density, bus width etc. EMIF has the capability to read these registers. If there are no devices connected to a given chip-select reading mode registers will return junk values. After reading as many such registers as possible and matching with expected ranges of values the driver can identify if there is a device connected to the respective CS. If we identify that a device is connected the values read give us complete details about the device. This along with the base AC timings specified by JESD209-2 allows us to do a complete automatic initialization of SDRAM that works on all boards. Please note that the default AC timings specified by JESD209-2 will be safe for all devices but not necessarily optimal. However, for the Elpida devices used on Panda and SDP the default timings are both safe and optimal. Signed-off-by: Aneesh V <aneesh@ti.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
2011-08-03omap4: calculate EMIF register valuesAneesh V
Calculate EMIF register values based on AC timing parameters from the SDRAM datasheet and the DDR frequency rather than using the hard-coded values. For a new board the user doen't have to go through the tedious process of calculating the register values. Instead, just provide the AC timings from the device data sheet as input and the driver will automatically calculate the register values.
