From 7e36e2f5355ab87f8946041d044b34cda01e2077 Mon Sep 17 00:00:00 2001 From: Rod Whitby Date: Tue, 1 Apr 2008 10:53:23 +0100 Subject: [ARM] 4874/2: ixp4xx: Add support for the Freecom FSG-3 board The Freecom-FSG3 is a small network-attached-storage device with the following feature set: * Intel IXP422 * 4MB Flash (ixp4xx flash driver) * 64MB RAM * 4 USB 2.0 host ports (ehci and ohci drivers) * 1 WAN (eth1) and 3 LAN (eth0) ethernet ports * Supported by the open source ixp4xx ethernet driver * Via VT6421 disk controller (libata and sata-via drivers) * Internal hard disk (PATA supported, SATA not yet supported) * External SATA port (not yet supported) * ISL1208 RTC chip * Winbond 83782 temp sensor and fan controller * MiniPCI slot The ixp4xx_defconfig is also updated to support this device (the leds-fsg driver is to be submitted separately via the leds tree after this initial support is merged, as it depends on header gpio defines).

No one implements dyntick on ARM anymore, so it's pointless keeping it around. Remove dyntick support.

Currently, they live side by side in pxa-regs.h, but only one set is available depending on the setting of PXA25x or PXA27x. This means that if we build to support both PXA25x and PXA27x, the PXA27x definitions are unavailable, even to PXA27x specific code. Remove these definitions from pxa-regs.h, and place them in separate files. Include these files where appropriate. Note: according to the dependencies in drivers/usb/gadget/Kconfig, we do not support the UDC on PXA27x nor PXA3xx CPUs, so remove the platform devices from pxa27x.c and pxa3xx.c.
