| * | sunxi: Add sun4i supportHans de Goede2014-07-06-3/+87
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for the Allwinner A10 SoC also known as the Allwinner sun4i family, and add the Cubieboard board which uses the A10 SoC. Compared to sun7 only the DRAM controller is a bit different: -Controller reset bits are inverted, but only for Rev.

First, the MC GCR register is set to 0 to reset all cores. MC firmware and DPL images are copied from their location in NOR flash to DDR. MC registers are updated with the location of these images. Deasserting the reset bit of MC GCR register releases core 0 to run. Core 1 will be released by MC firmware. Stop bits are not touched for this step. U-boot waits for MC until it boots up. In case of a failure, device tree is updated accordingly. The MC firmware image uses FIT format. Signed-off-by: J.

If we stop CLKM when sampling it the glitches all go away, so we'll do that as per Samsung suggestion. We also check the "is it locked" bits of PHY_CON13 and loop until they show the the value sampled actually represents a locked value. It doesn't appear that the glitching and "is it locked" are related, but it seems wise to wait until the PHY tells us the value is good before we use it. In practice we will not loop more than a couple times (and usually won't loop at all).

| * | Exynos5420: Remove code for enabling read levelingAkshay Saraswat2014-06-13-71/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch intends to remove all code which enables hardware read leveling. All characterization environments may not cope up with h/w read leveling enabled, so we must disable this. Also, disabling h/w read leveling improves the MIF LVcc value (LVcc value is the value at which DDR will fail to work properly). Improving LVcc means we have enough voltage margin for MIF. When h/w leveling is enabled, we have almost zero volatge margin.

However, if later a driver activates the timeout setting the reset to a valid value, the old reset value with zero is still valid for the first access. In fact, the timeout block loads the reset counter after a successful access. Found on a am335x board with a FPGA connected to the GPMC bus together with the NAND. When the FPGA driver in kernel activates the timeout, the system hangs at the first access by the NAND driver. Signed-off-by: Stefano Babic <sbabic@denx.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Similar to OMAP4/5 we need to scale the voltage up prior to changing the clock frequencies up higher. Add a similar hook to start with. Signed-off-by: Tom Rini <trini@ti.com>
* | | | ARM: AM43xx: Fix UART clocks enablingLokesh Vutla2014-06-06-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After enabling a module, SW has to wait on IDLEST bit until it is Fully functional. This wait is missing for UART module and there is a immediate access of UART registers after this. So there is a chance of hang on this module( This can happen when we are running from MPU SRAM). So waiting for IDLEST bit. Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com>
