93b61bddc1 Blackfin SPI Driver: Make mmc_spi driver work on Blackfin
1. Rewrite of the non-dma data transfer functions to use only ONE mode
   of TIMOD (TIMOD=0x1).  With TIMOD=0, it was not possible to set the TX
   bit pattern.  So the TDBR = 0xFFFF inside the read calls won't work.

2. Clear SPI_RDBR before reading and before duplex transfer.
   Otherwise the garbage data in RDBR will get read.  Since mmc_spi uses a
   lot of duplex transfers, this is the main cause of mmc_spi failure.

3. Poll RXS for transfer completion.  Polling SPIF or TXS cannot
   guarantee transfer completion.  This may interrupt a transfer before it
   is finished.  Also this may leave garbage data in buffer and affect
   next transfer.

42c78b2bf5 Blackfin SPI Driver: Add GPIO controlled SPI Slave Select support
Add support for GPIO controlled SPI Chip Selects.  To make use of this
feature, set chip_select = 0 and add a proper cs_gpio to your
controller_data.

struct spi_board_info
        .chip_select = 0

struct bfin5xx_spi_chip
        .cs_gpio = GPIO_P###

There are various SPI devices that require SPI MODE_0, and need to have
the Chip Selects asserted during the entire transfer.  Consider using
SPI_MODE_3 (SPI_CPHA | SPI_CPOL) if your device allows it.

b9b2a76a43 Blackfin SPI Driver: fix bug - correct usage of struct spi_transfer.cs_change
According to comments in linux/spi/spi.h:

 * All SPI transfers start with the relevant chipselect active.  Normally
 * it stays selected until after the last transfer in a message. Drivers
 * can affect the chipselect signal using cs_change.
 *
 * (i) If the transfer isn't the last one in the message, this flag is
 * used to make the chipselect briefly go inactive in the middle of the
 * message.  Toggling chipselect in this way may be needed to terminate
 * a chip command, letting a single spi_message perform all of group of
 * chip transactions together.
 *
 * (ii) When the transfer is the last one in the message, the chip may
 * stay selected until the next transfer.  On multi-device SPI busses
 * with nothing blocking messages going to other devices, this is just
 * a performance hint; starting a message to another device deselects
 * this one.  But in other cases, this can be used to ensure correctness.
 * Some devices need protocol transactions to be built from a series of
 * spi_message submissions, where the content of one message is determined
 * by the results of previous messages and where the whole transaction
 * ends when the chipselect goes intactive.

2cf3683472 Blackfin SPI Driver: fix bug - spi controller driver does not assert/deassert CS correctly
This bug can be observed when two SPI devices are sharing the spi bus: One
device is set as SPI CS 7, another one is using SPI CS 4.

In spi_bfin5xx.c: cs_active(), cs_deactive() are used to control SPI_FLG
register.  From the debug bellow:

cs_active: flag: 0x7f91, chip->flag: 0x7f80, cs: 7
cs_active: flag: 0xef91, chip->flag: 0xef10, cs: 4

When device A (cs_7) activate CS 7, SPI_FLG is set as 0x7f91 (however,
SPI_FLG should be set as 0x7f80, or 0x6f91 if in broadcast mode).

Due to some HW bug (very possibly), if SPI_FLG is set as 0x7f91, SPISSEL7
is asserted, however SPISSEL4 will be asserted too (I can see this using
the scope).  This is unreasonable according to HRM.

11d6f59951 Blackfin SPI Driver: get dma working for SPI flashes
When using a BF533-STAMP here with a W25X10 SPI flash.  It works fine when
enable_dma is disabled, but doesn't work at all when turning DMA on.  We
get just 0xff bytes back when trying to read the device.

Change the code around so that it programs the SPI first and then enables
DMA, it seems to work a lot better ...

Not critical.

  The function show_serial_version() references
  the variable __initdata serial_version.
  This is often because show_serial_version lacks a __initdata

d407e32efe PCI: Fix oops in pci_vpd_truncate
pci_vpd_truncate() should check for dev->vpd->attr, otherwise this might
happen:

  sky2 driver version 1.22
  Unable to handle kernel paging request for data at address 0x0000000c
  Faulting instruction address: 0xc01836fc
  Oops: Kernel access of bad area, sig: 11 [#1]

This happens with CONFIG_SKY2=y, and "ip=on" kernel command line, so
pci_vpd_truncate() is called before late_initcall(pci_sysfs_init),
therefore ->attr isn't yet initialized.

f08b7e9f55 powerpc/pmac: Fix internal modem IRQ on Wallstreet PowerBook
The (relatively) new pmac_zilog driver doesn't use the pre-munged
IRQ numbers from the macio_dev unlike other macio things, it
directly maps it off the OF device-tree.

It does that because it can be initialized much earlier than the
registration of the macio devices, in order to get a serial
console early.

Unfortunately, that means that it "misses" some fixups done
by the macio layer to work around missing interrupt descriptions
in the device-tree of the Wallstreet machines.

This patch brings the necessary workaround into the pmac_zilog
driver itself to bring it back to working condition.

b6966b1be5 powerpc/wdrtas: Update wdrtas_get_interval to use rtas_data_buf
The buffer passed to the ibm,get-system-parameter RTAS call must be
in the RMA.  To ensure we pass an address in the RMA use rtas_data_buf
for the actual RTAS call and then copy the result to value.  We can't
just make it static because this can be compiled in as a module.

Also add the WDRTAS_SP_SPI_LEN so we don't litter '4' throughout the
function.

37efa23990 b44: Use kernel DMA addresses for the kernel DMA API
We must not use the device DMA addresses for the kernel DMA API, because
device DMA addresses have an additional offset added for the SSB translation.

Use the original dma_addr_t for the sync operation.
