drivers/ide: PATA driver for Celleb
This is the patch (based on 2.6.19-rc4) for PATA controller of
Toshiba Cell reference set(Celleb). The reference set consists
of Cell, 512MB memory, Super Companion Chip(SCC) and some
peripherals such as HDD, GbE, etc. You can see brief explanation
and picture of Cell reference set at following URLs.
http://www.toshiba.co.jp/about/press/2005_09/pr2001.htm
http://cell-industries.com/toshiba_announces.php
We use a drivers/ide driver because its design is more suitable for
SCC IDE controller than libata driver. Since SCC supports only 32bit
read/write, we must override many callbacks of ata_port_operations
by modifying generic helpers. Each time the libata common code is
updated, we must update those modified helpers. It is very hard for us.
But we will try to implement the libata driver as needed.

- ide_dma_check() method tries to enable DMA on the "known good" drives which
don't support MWDMA2;
- ide_dma_on() method upon failure to set drive to MWDMA2 re-tunes already
tuned PIO mode and calls ide_dma_off() method instead of returning error;

USB: fix g_serial small error
A SET_LINE_CODING control request should return a zero length packet
as an ACK to the host, during the status phase of a USB transaction.
The return value of gs_setup_class() is treated as the number of
bytes to write in the status phase of the control request, by
gs_setup(). For this case, the value returned by gs_setup_class should
be zero for SET_LINE_CODING but, right now, appears to be
sizeof(struct usb_cdc_line_coding).
However, if after doing the memcpy of the line coding descriptor we
set the variable "ret" to be zero, we should return the appropiate ZLP
to the host as an ACK in the status phase of the control request.
I've tested this out using Linux as both host and slave and confirmed
that the following small change fixes the spurious return of
sizeof(struct usb_cdc_line_coding)/wLength bytes in the status phase

PCI-to-PCI-bridge (or something alike), but to me it seems a bit strange.
Please correct me, if I'm mislead.
The patch below is tested on the above mentioned CPCI-MPC5200 board and is
compiler tested with the latest git-repository kernel on x86.

PCI: Make CARDBUS_MEM_SIZE and CARDBUS_IO_SIZE boot options
CARDBUS_MEM_SIZE was increased to 64MB on 2.6.20-rc2, but larger size might
result in allocation failure for the reserving itself on some platforms
(for example typical 32bit MIPS). Make it (and CARDBUS_IO_SIZE too)
customizable by "pci=" option for such platforms.

PCI: pci.txt fix __devexit() usage
Marin Mitov <mitov@issp.bas.bg> spotted a brainfart where I had
failed to update copied text with *_remove and __devexit().
Marin made a good comment in his email to me:
| mydriver_probe() is _always_ executed, while mydriver_remove() is not.
| See: include/linux/init.h
Which says:
/* Functions marked as __devexit may be discarded at kernel link time, depending
on config options. Newer versions of binutils detect references from
retained sections to discarded sections and flag an error. Pointers to
__devexit functions must use __devexit_p(function_name), the wrapper will
insert either the function_name or NULL, depending on the config options.
