Create std.arm and std.armv6 config files and include the right one from each of the existing kernel configs. This gives a place to put config that applies to the entire arch. Add the ARM_NEW_PMAP option to std.armv6. This is working well in early testing and it's time for wide exposure, but it's still nice to be able to fall back to the old implementation for testing when a problem comes along. Eventually the option and the old implementation will go away. The opportunity now exists to move a whole lot of boilerplate from all the arm kernel config files into std.arm*, but that's a commit for another day. 2015-05-05 16:09:25 +00:00
Tag all armv7 kernels as such in their machine config line. Transition all boards that support arm cortex CPUs to armv7. This leaves two armv6 kernels in the tree. RPI-B, which uses the BCM2835 which has a ARM1176 core, and VERSATILEPB, which is a qemu board setup around the time RPI-B went in. Copy std.armv6 to std.armv7, even though that duplicates a lot of stuff. More work needs to be done to sort out the duplication.

Add etherswitch support to mge This commit introduces support for etherswitch devices that utilize SMI as a way of accessing its registers. SMI register is located in address space of mge -- access to it was exported through MDIO interface. Attachment functions were enhanced so as to ensure proper initialisation in both cases: 1) PHYs attached directly to mge, 2) PHYs attached to switch device and switch attached to mge. Attachment of etherswitch device depends on dts entry with compatible="mrvl,sw" property. If none is found, typical PHY attachment procedure follows. In case of switch attached, PHYs' status and configuration is accessible via etherswitchcfg, and ifconfig shows always-up, non-configurable mge interfaces. Due to the fact that there may be simultaneous accessess to SMI registers (e.g. from PHY attached to one of mge instances and switch to the other), SMI access interlock was added. It is SX lock, because sleep ability is necessary -- busy-waiting would result in poor performance due to long delays required by hardware. Underlying switch driver is obliged to use sleepable locks as well.

Enable ArmadaXP using INTRNG interrupt controller Defining INTRNG remove some necessary registers and declarations of pic_init_secondary, pic_ipi_send, pic_ipi_read and pic_ipi_clear. Because Marvell ArmadaXP and Armada38X always use INTRNG, include all INTRNG code and remove code that does not use it. Separate pic registers declarations for Armada38X are unnecessary, it works properly with ArmadaXP config.

Use PLATFORM for initializing Marvell ArmadaXP and Armada38X Spliting armv5 and armv7 machdep is necessary for adding Armada38X and ArmadaXP to GENERIC config. PLATFORM framework checks SOC type in FDT and will select proper initialization function implementation during runtime. Pointers to SoC specific implementation are stored in array of platform_method_t and provided to framework by FDT_PLATFORM_DEF macro. PLATFORM framework supports also reset function. To simplify implementation cpu_reset is moved from mv_common to armv5 and armv7 machdep. Armada38X and ArmadaXP share now common list of files, so resolve all dependencies as well.
