From 9d4f13e531b4722fe40cc8e28c02a495bdd49267 Mon Sep 17 00:00:00 2001 From: Russell King Date: Tue, 3 Jan 2006 17:28:33 +0000 Subject: [ARM] Make kernel link address depend on PAGE_OFFSET We are coding the kernel link address into the makefiles, which is invisibly dependent on PAGE_OFFSET. If PAGE_OFFSET is changed, the makefiles also need to be changed. Make adjustments such that the makefiles encode just the offset from PAGE_OFFSET for the kernel link address, and use PAGE_OFFSET in the linker scripts directly.

The NAS100D is a consumer device containing a 266MHz Intel IXP420 processor, 16MB of flash, 64MB of RAM, a 160Gb internal IDE hard disk, and 802.11b/g wireless on an Atheros mini-PCI card. Work on porting the latest 2.6.x kernel to this device is being done by the NSLU2-Linux project (the same team who maintains the port to the Linksys NSLU2 device). In particular, the majority of this patch was authored by Alessandro Zummo, based on the work done for MACH_NSLU2 support by the NSLU2-Linux core team of developers. MACH_NAS100D (as implemented by this patch) can be enabled in jumbo ixp4xx kernels without any affect on the other machines supported by that kernel. This patch applies cleanly against 2.6.15-rc7 and should be trivial to apply to later kernel versions. It does not depend upon any other patches.

Because of this, we cannot hardcode the physical base as we currently do. This patch checks the expansion bus configuration registers at runtime to determine the appropriate window size. Note that this requires that the bootloader already configured the device sizes appropriately, but I feel that is valid assumption to make as the bootloader must configure and access the flash window, the output display (LCD, LEDs, etc) window, and other expansion bus devices.
