* | MIPS: Use lower case for addresses in nexys4ddr.dtsPaul Burton2019-02-041-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DTC introduced an i2c_bus_reg check in v1.4.7, used since Linux v4.20, which complains about upper case addresses used in the unit name. nexys4ddr.dts names an I2C device node "ad7420@4B", leading to: arch/mips/boot/dts/xilfpga/nexys4ddr.dts:109.16-112.8: Warning (i2c_bus_reg): /i2c@10A00000/ad7420@4B: I2C bus unit address format error, expected "4b" Fix this by switching to lower case addresses throughout the file, as is *mostly* the case in the file already & fairly standard throughout the tree.

| | | | | | | | | | | | | Remove the Malta display platform code in favour of probing the img-ascii-lcd driver via device tree. This reduces the amount of platform code & the img-ascii-lcd driver offers us advantages in terms of code sharing with other boards & functionality such as changing the displayed message via sysfs. Defconfigs are untouched because the driver already defaults y on when CONFIG_MIPS_MALTA=y.

* MIPS: Boston: Disable EG20T prefetchPaul Burton2018-11-091-0/+6
| | | | | | | | | | | | | | | | | | | | The Intel EG20T Platform Controller Hub used on the MIPS Boston development board supports prefetching memory to optimize DMA transfers. Unfortunately for unknown reasons this doesn't work well with some MIPS CPUs such as the P6600, particularly when using an I/O Coherence Unit (IOCU) to provide cache-coherent DMA. In these systems it is common for DMA data to be lost, resulting in broken access to EG20T devices such as the MMC or SATA controllers. Support for a DT property to configure the prefetching was added a while back by commit 549ce8f134bd ("misc: pch_phub: Read prefetch value from device tree if passed") but we never added the DT snippet to make use of it. Add that now in order to disable the prefetching & fix DMA on the affected systems.
