* omap3:clock: check cpu_family before enabling clks for IVA & CAMVaibhav Hiremath2011-09-04-4/+10
| | | | | | | | | | | In case of AM3517 and AM3505 (which is OMAP3 varients), IVA2 and ISP-CAMERA modules have been removed. So add check for cpu_family before enabling clocks for these modules, else this impacts subsequent power consumption and system suspend/resume functionality.

* omap3:clock: configure GFX clock to 200MHz for AM/DM37xVaibhav Hiremath2011-09-04-1/+2
| | | | | | | | | | | | AM/DM37x is another OMAP3 variant, where the GFX clock has been boosted to 192MHz/200MHz. So fix the GFX_DIV value for this change. HW Errata: Due to dependency of TV out clock of 54MHz, it is not possible to configure GFX to 192MHz. So as per HW errats, the recommended GFX clock is 200MHz (=CORE_CLK/2).

* armv7: cache: remove flush on un-aligned invalidateAneesh V2011-09-04-12/+17

* armv7: stronger barrier for cache-maintenance operationsAneesh V2011-09-04-6/+6
| | | | | | | | 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>

* arm: do not force d-cache enable on all boardsAneesh V2011-09-04-5/+15
| | | | | | | | | | | | 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>
* i2c:gpio:s5p: I2C GPIO Software implementation (via soft_i2c)Łukasz Majewski2011-09-04-0/+42

* MX: MX35 / MX5: uniform clock command with powerpcStefano Babic2011-09-04-4/+4
| | | | | | | | | | | 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>
* ARM: MX51: PLL errata workaroundDavid Jander2011-09-04-0/+43
| | | | | | | | | | | | | 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.

* gpio:samsung s5p_ suffix add for GPIO functionsŁukasz Majewski2011-09-03-16/+16
| | | | | | | | | | | | | | 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).

* integrator: convert to new build systemLinus Walleij2011-09-03-5/+0
| | | | | | | | | | | | | | | | | 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.
