2014-01-22MIPS: Add support for interAptiv coresLeonid Yegoshin
The interAptiv is a power-efficient multi-core microprocessor for use in system-on-chip (SoC) applications. The interAptiv combines a multi-threading pipeline with a coherence manager to deliver improved computational throughput and power efficiency. The interAptiv can contain one to four MIPS32R3 interAptiv cores, system level coherence manager with L2 cache, optional coherent I/O port, and optional floating point unit.

The Fixed Page Size TLB (FTLB) is a set-associative dual entry TLB.

2014-01-22MIPS: Malta: Remove ttyS2 serial for CMP platformsLeonid Yegoshin
Commit 225ae5fd9a320e22841410049c3bdb6cf14a5841 "MIPS: Malta: Fix interupt number of CBUS UART" fixed the IRQ number for the ttyS2 CBUS UART. However, this now conflicts with the GIC IPI1 interrupt in CMP platforms. The Malta interrupt code arbitrarily binds IPIs to INT2 and INT3 and since ttyS2 uses the INT2 IRQ line, closing the device disables the INT2 interrupt and this effectively disables the IPI1 interrupt as well. This patch is mainly a workaround until the Malta code is fixed properly.
