Notes: Usually one wants to do small reads and write a longword, but +! unfortunately it is difficult in some cases to concatanate bytes +! into a longword on the SH, so this does a longword read and small +! writes. +! +! This implementation makes two assumptions about how it is called: +! +! 1.: If the byte count is nonzero, the address of the last byte to be +! copied is unsigned greater than the address of the first byte to +! be copied. This could be easily swapped for a signed comparison, +! but the algorithm used needs some comparison. +! +! 2.: When there are two or three bytes in the last word of an 11-or-more +! bytes memory chunk to b copied, the rest of the word can be read +! without side effects. +! This could be easily changed by increasing the minumum size of +! a fast memcpy and the amount subtracted from r7 before L_2l_loop be 2, +! however, this would cost a few extra cyles on average. +! For SHmedia, the assumption is that any quadword can be read in its +! enirety if at least one byte is included in the copy. + +/* Imported into Linux kernel by Richard Curnow.

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.

When a get_user(to, from++) is called the pointer increment is performed after its first usage, in the specific after the __add_ok invokation. This causes a wrong get_user return value, putting a wrong character in the destination variable. This patch solves the problem using a new temporary pointer. Additionally this reworks the use of the register banks, allowing for consolidation between the MMU and nommu implementations.

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.

Optimal priority assignment varies with embedded application anyway, so keeping the interrupt priority tables together with cpu-specific code doesn't make sense. The function intc_set_priority() should be used instead to set the desired interrupt priority level.

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.

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.
