TPS SET0/SET1 register is selected by a GPIO pin on OMAP4460 platforms.
Currently we control this pin with a mux configuration as part of
boot sequence.
Current configuration results in the following voltage waveform:
|---------------| (SET1 default 1.4V)
| --------(programmed voltage)
| <- (This switch happens on mux7,pullup)
vdd_mpu(TPS) -----/ (OPP boot voltage)
--------- (programmed voltage)
vdd_core(TWL6030) -----------------------/ (OPP boot voltage)
Problem 1) |<----- Tx ------>|
timing violation for a duration Tx close to few milliseconds.
Problem 2) voltage of MPU goes beyond spec for even the highest of MPU OPP.
By using GPIO as recommended as standard procedure by TI, the sequence
changes to:
-------- (programmed voltage)
vdd_mpu(TPS) ------------/ (Opp boot voltage)
--------- (programmed voltage)
vdd_core(TWL6030) -------------/ (OPP boot voltage)

Add parameters to the OMAP MMC initialization function so the board can
mask host capabilities and set the maximum clock frequency. While the
OMAP supports a certain set of MMC host capabilities, individual boards
may be more restricted and the OMAP may need to be configured to match
the board. The PRG_SDMMC1_SPEEDCTRL bit in the OMAP3 is an example.

this patch addresses the issue that there is no DVI output on beagleboard-xm in
u-boot; the TFP410 is not powered on, DVI_PUP needs to be set high
this is done differently on beagleboard-xm rev. B/C versus earlier boards:
beagleboard-xm B/C need to set GPIO2 of the TWL4030
earlier boards need to set GPIO170
note that the change occured somewhere inbetween beagleboard-xm rev. A2 and A3
note that beagleboard-xm rev. A and rev. B cannot be distinguished using
get_board_revision(), REVISION_XM_A/REVISION_XM_B is bogus
due to this glitch, the patch cannot work correctly on some beagleboard-xm
rev A/B boards
tested on beagleboard-xm rev. C (you should see orange color on a monitor)
note that the framebuffer is NOT yet set up, this could be done along the
lines below (for 800x480 resolution and RGB24) before calling omap3_dss_enable()
static void configure_frame_buffer() {
writel(0x80500000, (uint *) 0x48050480); // address

TPS power IC is controlled using a GPIO (gpio_wk7).
This GPIO should be maintained at logic 1 always. As
such an internal pull-up on this pin will do the job,
driving the GPIO outuput is not needed. This will avoid
the need of using GPIO library in SPL and also may
save some power.

Configuration header(CH) is 512 byte header attached to an OMAP
boot image that will help ROM code to initialize clocks, SDRAM
etc and copy U-Boot directly into SDRAM. CH can help us in
by-passing SPL and directly boot U-boot, hence it's an alternative
for SPL. However, we intend to support both CH and SPL for OMAP4/5.
Initialization done through CH is limited and is not equivalent
to that done by SPL. So U-Boot has to distinguish between the
two cases and handle them accordingly. This patch takes care
of doing this.

This patch adds the minimal support for OMAP5. The platform and machine
specific headers and sources updated for OMAP5430.
OMAP5430 is Texas Instrument's SOC based on ARM Cortex-A15 SMP architecture.
It's a dual core SOC with GIC used for interrupt handling and SCU for cache
coherency.
Also moved some part of code from the basic platform support that can be made
common for OMAP4/5. Rest is kept out seperately. The same approach is followed
for clocks and emif support in the subsequent patches.

New u-boot command for status of USER button on BeagleBoard-xM
Modified bootcmd to check the staus at boot time and set
filename of the boot script.
* Moved to a BeagleBoard specific file.
* Removed changes to default boot command from adding userbutton
command.
* Made to handle pre-xM boards.
* Flipped polarity of the return value to avoid confusion. Success (0)
is when the button is pressed. Failure (1) is when the button is NOT
pressed.
* Used latest revision getting function.
* Used latest macros for board revision.
* Added xM-C revision definition (optional, since it was default)
* updated default configuration with UserButton functionality
* Added a separate bootenv variable to load a user defined .txt file
* Added an example, showing how a different environment file can be loaded with
