This implements kernel-level atomic rollback built on top of gUSA, as an alternative non-IRQ based atomicity method. This is generally a faster method for platforms that are lacking the LL/SC pairs that SH-4A and later use, and is only supportable on legacy cores.

Presently most of the 29-bit physical parts do P1/P2 segmentation with a 1:1 cached/uncached mapping, jumping between the two to control the caching behaviour. This provides the basic infrastructure to maintain this behaviour on 32-bit physical parts that don't map P1/P2 at all, using a shiny new linker section and corresponding fixmap entry.

This patch changes the uImage target so that it generates a wrapped compressed vmlinux, rather than a wrapped zImage. The previous version matched the ARM, this version matches the PPC. However I would question how useful a self decompressing image is with a boot loader which does decompression, so I think this is more useful. I also feel it matches the descrition in the help text ("Compressed kernel image") better.

The sm501fb driver should leave the pins FPEN and VBIASEN alone, and this patch instructs the driver to do so by not setting flags flags for these pins. This patch works best together with the patch posted to the linux-fbdev-devel list "sm501fb: control panel pin usage with platform data flags", but this patch can be merged independently.

This patch adds support for the GD-Rom drive, SEGA's proprietary implementation of an IDE CD Rom for the SEGA Dreamcast. This driver implements Sega's Packet Interface (SPI) - at least partially. It will also read disks in SEGA's propreitary GD format. Unlike previous drivers (which were never in mainline) this uses DMA and not PIO to read disks. It is a new driver, not a refactoring of old drivers.

Some of Sam's new work in the kbuild queue depend on ## concatenation within the linker script, which doesn't work when -traditional is enabled. -traditional is a legacy remnant anyways, and we no longer require it for anything, so kill it off completely.

All functions are based on the x86 implementation. Header files are adjusted to use the new functions instead of the former consistent_alloc() code. This version includes the few changes what were included in the fix patch together with modifications based on feedback from Paul.

The new code is very similar to the other highlander implementations, with the exception that the r7780rp handles pci interrupts using IRL. To simplify the pci code and use the same interrupt numbers as r7780mp and r7785rp we hook in to the cpu specific pci vectors. The pci interrupts and the push switch all work well with and without this patch. CF and AX88796 are not ok though and the source of the problem is unknown at this point. The AX88796 does for not detect it's proper mac address (IPL gets it right) and the kernel hangs on CF access. As a workaround this patch removes the CF and the AX88796 from the platform datain case of r7780rp.

The header file contains a structure that should be used to point out a single spi bus. The board specific code for r2d is updated with such a structure for the new spi_sh_sci driver. The structure contains a chip select callback plus information about the R9701 rtc chip which is attached to the spi bus.
