* ARM: tegra: Enable non-cached memoryThierry Reding2014-12-18-1/+3
| | | | | | | | | | | | | Some boards, most notably those with a PCIe ethernet NIC, require this to avoid cache coherency problems. Since the option adds very little code and overhead enable it across all Tegra generations. Other drivers may also start supporting this functionality at some point, so enabling it now will automatically reap the benefits later on.

* ARM: Implement non-cached memory supportThierry Reding2014-12-18-0/+79
| | | | | | | | | | | | | | | | | | | | | | Implement an API that can be used by drivers to allocate memory from a pool that is mapped uncached. This is useful if drivers would otherwise need to do extensive cache maintenance (or explicitly maintaining the cache isn't safe). The API is protected using the new CONFIG_SYS_NONCACHED_MEMORY setting. Boards can set this to the size to be used for the non-cached area. The area will typically be right below the malloc() area, but architectures should take care of aligning the beginning and end of the area to honor any mapping restrictions. Architectures must also ensure that mappings established for this area do not overlap with the malloc() area (which should remain cached for improved performance). While the API is currently only implemented for ARM v7, it should be generic enough to allow other architectures to implement it as well.

This IP core is integrated on the Altera SoCFPGA. This implementation is a driver model (DM) implementation. So multiple SPI drivers can be used. Thats necessary, since SoCFPGA also integrates the Cadence QSPI controller used to connect the SPI NOR flashes. Without DM, using multiple SPI drivers is not possible. This driver is very loosely based on the Linux driver. Most of the Linux driver is removed. Only the polling loop for the transfer is really used from this driver, as we don't support interrupts and DMA right now. This is tested on the SoCrates SoCFPGA board using the SPI pins on the P14 header.

I used this git tag: ACDS14.0.1_REL_GSRD_RC2. With Some modification to support the U-Boot driver model (DM). As mentioned above, in this new version I ported this driver to the new driver model (DM). One big advantage of this move is that now multiple SPI drivers can be enabled on one platform. And since the SoCFPGA also has the Designware SPI master controller integrated, this feature is really needed to support both controllers. Because of this, this series needs the DT support for SoCFPGA to be applied. For DT based probing in the SPI DM.
