Sergei Shtylyov dab8c6deaf [MIPS] Au1200: MMC resource size off by one
Au12x0 MMC platform device strangely claims 0x41 bytes for its
memory-mapped registers.  Make it claim the whole 0x80000 instead according
to the memory map given in the datasheets.

Thomas Horsten 1f34f2e426 [MIPS] Lasat: sysctl fixup
LASAT's sysctl interface was broken, it failed a check during boot because
a single entry had a sysctl number and the rest were unnumbered. When I
fixed it I noticed that the whole sysctl file needed a spring clean, it was
using mutexes where it wasn't needed (it's only needed to protect during
writes to the EEPROM), so I moved that stuff out and generally cleaned the
whole thing up.

So now, LASAT's sysctl/proc interface is working again.

Maciej W. Rozycki 461a082f87 [MIPS] Bring the SWARM defconfig up to date
The SWARM defconfig file has not been regenerated for over a year now.
Here is a patch to bring the file up to date.  Additionally some important
and sometimes confusing changes happened meanwhile.  Here is the list of
notable corresponding updates to the configuration:

1. CPU_SB1_PASS_2_2 is now selected rather than CPU_SB1_PASS_1.  The
   latter requires a non-standard -msb1-pass1-workarounds option to be
   supported by GCC and I am told is quite rare anyway.

   [Ralf: Afaik -msb1-pass1-workarounds is available only in Monta Vista's
   special Sibyte gcc 3.0 variant and gcc 3.0 is too old to build a modern
   kernel anyway.]

2. PHYLIB and BROADCOM_PHY are both built in and NETDEV_1000 enabled as
   required by SB1250_MAC.

3. USB and USB_OHCI_HCD are enabled as there is an OHCI chip onboard.

4. TMPFS is enabled, because I use it. ;-)

This enables CONFIG_ATA_SFF in the defconfigs that are intended to

the support for the SATA cell in the K2 chipset is provided by the
sata_svw.c driver, and that depends on CONFIG_ATA_SFF, we need to turn
that and CONFIG_SATA_SVW back on so we can get to the hard disk on G5s.

Kumar Gala da3de6df33 [POWERPC] Fix -Os kernel builds with newer gcc versions
GCC 4.4.x looks to be adding support for generating out-of-line register
saves/restores based on:

http://gcc.gnu.org/ml/gcc-patches/2008-04/msg01678.html

This breaks the kernel if we enable CONFIG_CC_OPTIMIZE_FOR_SIZE.  To fix
this we add the use the save/restore code from gcc and simplified it down
for our needs (integer only).

Additionally, we have to link this code into each module.  The other
solution was to add EXPORT_SYMBOL() which meant going through the
trampoline which seemed nonsensical for these out-of-line routines.

Finally, we add some checks to prom_init_check.sh to ignore the
out-of-line save/restore functions.

http://gcc.gnu.org/ml/gcc-patches/2008-04/msg01678.html

Bartlomiej Zolnierkiewicz 07a6c66da5 ide-pmac: add ->cable_detect method
Add ->cable_detect method and remove no longer needed pmif->cable_80 flag
(there is also no need to mask ->udma_mask now).

This fixes:

- forced ignoring of cable detection (needed for some CF devices & debug)

- cable detection for warm-plug

    ide: rework PowerMac media-bay support (take 2)
...

[ Yeah, I suck. ]

bay->cd_index shouldn't be changed if IDE devices are not present
or retry operations won't happen.

Bartlomiej Zolnierkiewicz 6c987183fc opti621: program devices timings separately in ->set_pio_mode

  then simplify selecting maximum adress setup timing.

* Remove no longer needed compute_pios() and opti621_port_init_devs().

* Program devices timings separately in ->set_pio_mode.
