From c9b4470e2d9d611181fe488fdf463948d8b24901 Mon Sep 17 00:00:00 2001 From: Lennert Buytenhek Date: Sun, 26 Mar 2006 21:40:27 +0100 Subject: [ARM] 3414/1: ep93xx: reset ethernet controller before uncompressing Patch from Lennert Buytenhek The Redboot version that cirrus supplies for the cirrus ep93xx doesn't turn off DMA from the ethernet MAC before jumping to linux, which means that we might end up with bits of RX status and packet data scribbled over the uncompressed kernel image. Work around this by resetting the ethernet MAC before we uncompress. We don't usually work around bootloader bugs, but considering that the large majority of ep93xx boards out there have this problem, I figured this it was justified in this case.

This is an ARMv5 ISA core with the following additions: - L2 cache - I/O coherency support (on select chipsets) - Low-Locality Reference cache attributes (replaces mini-cache) - Supersections (v6 compatible) - 36-bit addressing (v6 compatible) - Single instruction cache line clean/invalidate - LRU cache replacement (vs round-robin) I attempted to merge the XSC3 support into proc-xscale.S, but XSC3 cores have separate errata and have to handle things like L2, so it is simpler to keep it separate. L2 cache support is currently a build option because the L2 enable bit must be set before we enable the MMU and there is no easy way to capture command line parameters at this point. There are still optimizations that can be done such as using LLR for copypage (in theory using the exisiting mini-cache code) but those can be addressed down the road.

The ixp23xx is an XSC3 based CPU with 512K of L2 cache, a 64bit 66MHz PCI interface, two DDR RAM interfaces, QDR RAM interfaces, two gigabit MACs, two 10/100 MACs, expansion bus, four microengines, a Media and Switch Fabric unit almost identical to the one on the ixp2400, two xscale (8250ish) UARTs and a bunch of other stuff. This patch adds the core ixp23xx support code, and support for the ADI Engineering Roadrunner, Intel IXDP2351, and IP Fabrics Double Espresso platforms.
