2013-09-20ARM: OMAP5: Avoid writing into LDO SRAM bitsLokesh Vutla
Writing magic bits into LDO SRAM was suggested only for OMAP5432 ES1.0. Now these are no longer applicable. Moreover these bits should not be overwritten as they are loaded from EFUSE. So avoid writing into these registers. Boot tested on OMAP5432 ES2.0 Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com>

DRA752 now uses AVS Class 0 voltages which are voltages in efuse. This means that we can now use the optimized voltages which are stored as mV values in efuse and program PMIC accordingly.

2013-06-10OMAP3+: introduce generic ABB supportAndrii Tseglytskyi
Adaptive Body Biasing (ABB) modulates transistor bias voltages dynamically in order to optimize switching speed versus leakage. Adaptive Body-Bias ldos are present for some voltage domains starting with OMAP3630. There are three modes of operation: * Bypass - the default, it just follows the vdd voltage * Foward Body-Bias - applies voltage bias to increase transistor performance at the cost of power. Used to operate safely at high OPPs. * Reverse Body-Bias - applies voltage bias to decrease leakage and save power. Used to save power at lower OPPs.

2013-06-06am33xx/omap4+: Move SRAM_SCRATCH_SPACE_ADDR to <asm/arch/omap.h>Tom Rini
The location of valid scratch space is dependent on SoC, so move that there. On OMAP4+ we continue to use SRAM_SCRATCH_SPACE_ADDR. On am33xx/ti814x we want to use what the ROM defines as "public stack" which is the area after our defined download image space. Correct the comment about and location of CONFIG_SPL_TEXT_BASE.

2013-05-10ARM: OMAP: Correct save_boot_params and replace with 'C' functionSRICHARAN R
Currently save_boot_params saves the boot parameters passed from romcode. But this is not stored in a writable location consistently. So the current code would not work for a 'XIP' boot.

2013-05-10ARM: OMAP5: Fix warm reset with USB cable connectedLokesh Vutla
Warm reset on OMAP5 freezes when USB cable is connected. Fix requires PRM_RSTTIME.RSTTIME1 to be programmed with the time for which reset should be held low for the voltages and the oscillator to reach stable state. There are 3 parameters to be considered for calculating the time, which are mostly board and PMIC dependent. -1- Time taken by the Oscillator to shut + restart -2- PMIC OTP times -3- Voltage rail ramp times, which inturn depends on the PMIC slew rate and value of the voltage ramp needed. In order to keep the code in u-boot simple, have a way for boards to specify a pre computed time directly using the 'CONFIG_OMAP_PLATFORM_RESET_TIME_MAX_USEC' option. If boards fail to specify the time, use a default as specified by 'CONFIG_DEFAULT_OMAP_RESET_TIME_MAX_USEC' instead. Using the default value translates into some ~22ms and should work in all cases. However in order to avoid this large delay hiding other bugs, its recommended that all boards look at their respective data sheets and specify a pre computed and optimal value using 'CONFIG_OMAP_PLATFORM_RESET_TIME_MAX_USEC' In order to help future board additions to compute this config option value, add a README at doc/README.omap-reset-time which explains how to compute the value. Also update the toplevel README with the additional option and pointers to doc/README.omap-reset-time.
