| | | | | | | | | | | | | | | | | | | The indirect read code is a pile of nastiness. This patch replaces the whole unmaintainable indirect read implementation with the one from upcoming Linux CQSPI driver, which went through multiple rounds of thorough review and testing. All the patch does is it plucks out duplicate ad-hoc code distributed across the driver and replaces it with more compact code doing exactly the same thing.

* mtd: cqspi: Simplify indirect write codeMarek Vasut2016-05-06-96/+30
| | | | | | | | | | | | | | | | | | | | | | | | | The indirect write code is buggy pile of nastiness which fails horribly when the system runs fast enough to saturate the controller. The failure results in some pages (256B) not being written to the flash. This can be observed on systems which run with Dcache enabled and L2 cache enabled, like the Altera SoCFPGA. This patch replaces the whole unmaintainable indirect write implementation with the one from upcoming Linux CQSPI driver, which went through multiple rounds of thorough review and testing. While this makes the patch look terrifying and violates all best-practices of software development, all the patch does is it plucks out duplicate ad-hoc code distributed across the driver and replaces it with more compact code doing exactly the same thing.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At present this SPI driver works by searching the PCI buses for its peripheral. It also uses the legacy PCI API. In addition the driver has code to determine the type of Intel PCH that is used (version 7 or version 9). Now that we have proper PCH drivers we can use those to obtain the information we need. While the device tree has a node for the SPI peripheral it is not in the right place. It should be on the PCI bus as a sub-peripheral of the LPC device. Update the device tree files to show the SPI controller within the PCH, so that PCI access works as expected.
