* [MIPS] Alchemy: Au1210/Au1250 CPU supportManuel Lauss2008-01-293-0/+13
| | | | | | | | | | This patch adds IDs for new Au1200 variants: Au1210 and Au1250. They are essentially identical to the Au1200 except for the Au1210 which has a different SoC-ID in the PRId register [bits 31:24]. The Au1250 is a "Au1200 V0.2".

* [MIPS] Eleminate local symbols from the symbol table.Ralf Baechle2008-01-297-281/+282
| | | | | | | | | These symbols appear in oprofile output, stacktraces and similar but only make the output harder to read. Many identical symbol names such as "both_aligned" were also being used in multiple source files making it impossible to see which file actually was meant. So let's get rid of them.

* [MIPS] R4000/R4400 daddiu erratum workaroundMaciej W. Rozycki2008-01-298-79/+198
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This complements the generic R4000/R4400 errata workaround code and adds bits for the daddiu problem. In most places it just modifies handwritten assembly code so that the assembler is allowed to use a temporary register as daddiu may now be treated as a macro that expands to a sequence of li and daddu. It is the AT register or, where AT is unavailable or used explicitly for another purpose, an explicitly-named register is selected, using the .set at=<reg> feature added recently to gas. This feature is only used if CONFIG_CPU_DADDI_WORKAROUNDS has been set, so if the workaround remains disabled, the required version of binutils stays unchanged. Similarly, daddiu instructions put in branch delay slots in noreorder fragments are now taken out of them and the assembler is allowed to reorder them itself as possible (which it does making the whole idea of scheduling them into delay slots manually questionable). Also in the very few places where such a simple conversion was not possible, a handcoded longer sequence is implemented. Other than that there are changes to code responsible for building the TLB fault and page clear/copy handlers to avoid daddiu as appropriate. These are only effective if the erratum is verified to be present at the run time. Finally there is a trivial update to __delay(), because it uses daddiu in a branch delay slot.

* [MIPS] R4000/R4400 errata workaroundsMaciej W. Rozycki2008-01-294-28/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the gereric part of R4000/R4400 errata workarounds. They include compiler and assembler support as well as some source code modifications to address the problems with some combinations of multiply/divide+shift instructions as well as the daddi and daddiu instructions. Changes included are as follows: 1. New Kconfig options to select workarounds by platforms as necessary. 2. Arch top-level Makefile to pass necessary options to the compiler; also incompatible configurations are detected (-mno-sym32 unsupported as horribly intrusive for little gain). 3. Bug detection updated and shuffled -- the multiply/divide+shift problem is lethal enough that if not worked around it makes the kernel crash in time_init() because of a division by zero; the daddiu erratum might also trigger early potentially, though I have not observed it. On the other hand the daddi detection code requires the exception subsystem to have been initialised (and is there mainly for information). 4. r4k_daddiu_bug() added so that the existence of the erratum can be queried by code at the run time as necessary; useful for generated code like TLB fault and copy/clear page handlers. 5. __udelay() updated as it uses multiplication in inline assembly. Note that -mdaddi requires modified toolchain (which has been maintained by myself and available from my site for ~4years now -- versions covered are GCC 2.95.4 - 4.1.2 and binutils from 2.13 onwards). The -mfix-r4000 and -mfix-r4400 have been standard for a while though. Signed-off-by: Maciej W. Rozycki <macro@linux-mips.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

| * sh: add spi header and r2d platform data V3Magnus Damm2008-01-281-0/+42
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds the header file asm/spi.h and board specific code for the r2d board. 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.

| * sh: update r7780rp interrupt codeMagnus Damm2008-01-285-74/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch updates the board specific irq code for r7780rp. 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. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
