Maciej W. Rozycki 20d60d9973 [MIPS] R4000/R4400 errata workarounds
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.

This patch refactors the code in corgi_lcd.c moving it to the board
specific corgi and spitz files where appropriate instead of the
existing ifdef mess which hinders readability.

Fix spitz_get_hsync_len() to call get_hsync_invperiod so pxafb can be
compiled as a module.

The confusing variables which represent the inverse horizintal sync
period are renamed to "invperiod" consistently.

An incorrect comment in corgi_ts.c is also corrected.

Robert Schwebel 2e927b7626 [ARM] 4747/1: pcm027: support for pcm990 baseboard for phyCORE-PXA270
This patch adds baseboard support for the phyCORE-PXA270 development
kit (aka PCM-990).

This example shows how to use some phyCORE-PXA270 CPU module features
on a baseboard in a standard manner. It could be used as a starting
point for custom baseboard development.

V2:
 After comments by Eric Miao:
  - IRQ chained handler fixed
  - video/graphic support moved to separate patch
  - ifdef/endif hell reduced ;-)

custom variant.

Russell King e7b3dc7ef1 [NET] smc91x: Make smc91x use IRQ resource trigger flags
smc91x is shared between many different platforms.  Each platform needs
to specify the interrupt type, and in some cases the irq type depends
on more than just the build configuration - it depends on runtime
checks.

Rather than throwing this code into the SMC_IRQ_FLAGS definition, provide
a way for these flags to be passed via the IRQ resource itself.

Note that IRQF_TRIGGER_* constants are intentionally defined to correspond
with the IORESOURCE_IRQ_* interrupt type flags, in much the same way that
the low bits of PCI iomem resources correspond with the BAR flag bits.

Also provide a way to configure smc91x to read the IRQ flags from the
resource.  Once all platforms have been converted over (signified
by all definitions of SMC_IRQ_FLAGS being -1) SMC_IRQ_FLAGS should
be removed.

Kiyoshi Ueda 650e9cfd14 blk_end_request: changing arm (take 4)
This patch converts arm's OMAP mailbox driver to use
blk_end_request interfaces.

If the original code was converted literally, blk_end_request would
be called with '-EIO' because end_that_request_last() were called
with '0' (i.e. failure).
But I think these '0's are bugs in the original code because it's
unlikely that all requests are treated as failure.
(The bugs should have no effect unless these requests have an end_io
 callback.)

So I changed them to pass '0' (i.e. success) to blk_end_request.

Magnus Damm da2d7f4bc5 sh: update r7780rp interrupt code
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.
