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.

2013-06-06ARM: tegra: only enable SCU on Tegra20Tom Warren
The non-SPL build of U-Boot on Tegra only runs on a single CPU, and hence there is no need to enable the SCU when running U-Boot. If an SMP OS is booted, and it needs the SCU enabled, it will enable the SCU itself. U-Boot doing so is redundant. The one exception is Tegra20, where an enabled SCU is required for some aspects of PCIe to work correctly. Some Tegra SoCs contain CPUs without a software-controlled SCU. In this case, attempting to turn it on actively causes problems. This is the case for Tegra114. For example, when running Linux, the first (or at least some very early) user-space process will trigger the following kernel message: Unhandled fault: imprecise external abort (0x406) at 0x00000000 This is typically accompanied by that process receving a fatal signal, and exiting. Since this process is usually pid 1, this causes total system boot failure.

Prior to Sricharan's cleanup of the boot parameter saving code, we did not make use of NON_SECURE_SRAM_START on am33xx, so it wasn't a problem that the address was pointing to the middle of our running SPL. Correct to point to the base location of the download image area. Increase CONFIG_SPL_TEXT_BASE to account for this scratch area being used. As part of correcting these tests, make use of the fact that we've always been placing our stack outside of the download image area (which is fine, once the downloaded image is run, ROM is gone) so correct the max size test to be the ROM defined top of the download area to where we link/load at.

When adjusting peripheral clocks always use find_best_divider() instead of clk_get_divider() even when a secondary divider is not available. In the case where is requested clock is too slow to be derived from the parent clock this allows a best effort to get close to the requested clock.
