afaa9f65c2 SPI: mxc_spi: add SPI clock calculation and setup to the driver
The MXC SPI driver didn't calculate the SPI clock up to
now and just used highest possible divider 512 for DATA
RATE in the control register. This results in very low
transfer rates.

The patch adds code to calculate and setup the SPI clock
frequency for transfers.

dff0109496 SPI: mxc_spi: fix swapping bug and add missing swapping in unaligned rx case
We need to shift only one time in each cycle in the swapping loop
for unaligned tx case. Currently two byte shift operations are
performed in each loop cycle causing zero gaps in the transmited
data, so not all data scheduled for transmition is actually
transmited.

The proper swapping in unaligned rx case is missing, so add it
as we need to put the received data into the rx buffer in the
correct byte order.

81687212ee I2C: mxc_i2c: address failure with mx35 processor
There is sporadic failures when more as one I2C slave
is on the bus and the processor tries to communicate
with more as one slave.
The problem was seen on a mx35pdk (two I2C slaves,
PMIC controller and CAN/RTC chip).

The current driver uses the IIF bit in the status register
to check if the bus is busy or not. According to the manual,
this is not correct, because the IIB bit should be checked.
Not only, to check if a transfer is finished must be checked
the ICF bit, and this is not tested at all.

This patch comes from analyse with a corresponding driver
provided by Freescale as part of the LTIB tool. Comparing
the two drivers, it appears that the current u-boot driver checks
the wrong bits, and depending on race condition, the transfer
can be successful or not.

The patch gets rid also of own debug function (DPRINTF),
replaced with the general debug().

Tested on Freescale mx35pdk.

213ac73e2c fsl_pci: Update PCIe boot ouput
This change does the following:
- Adds printing of negotiated link width.  This information can be
  useful when debugging PCIe issues.
- Makes it optional for boards to implement board_serdes_name().
  Previously boards that did not implement it would print unsightly
  output such as "PCIE1: Connected to <NULL>..."
- Rewords the PCIe boot output to reduce line length and to make it
  clear that the "base address XYZ" value refers to the base address of
  the internal processor PCIe registers and not a standard PCI BAR
  value.
- Changes "PCIE" output to the standard "PCIe"

Before change:
PCIE1: connected to <NULL> as Root Complex (base addr ef008000)
  01:00.0     - 10b5:8518 - Bridge device
   02:01.0    - 10b5:8518 - Bridge device
   02:02.0    - 10b5:8518 - Bridge device
   02:03.0    - 10b5:8518 - Bridge device
PCIE1: Bus 00 - 05
PCIE2: connected to <NULL> as Endpoint (base addr ef009000)
PCIE2: Bus 06 - 06

After change:
PCIe1: Root Complex of PEX8518 Switch, x4, regs @ 0xef008000
  01:00.0     - 10b5:8518 - Bridge device
   02:01.0    - 10b5:8518 - Bridge device

a4aafcc990 powerpc/fsl-pci: Add generic code to setup PCIe controllers
Since all the PCIe controllers are connected over SERDES on the SoCs we
can utilize is_serdes_configured() to determine if a controller is
enabled.  After which we can setup the ATMUs and LAWs for the controller
in a common fashion and allow board code to specify what the controller
is connected to for reporting reasons.

We also provide a per controller (rather than all) for some systems that
may have special requirements.

Finally, we refactor the code used by the P1022DS to utilize the new
generic code.

This adds support for for the PCA9535/PCA9539 family of gpio devices which

To let the driver know which devices are 16-pin it is necessary to define
CONFIG_SYS_I2C_PCA953X_WIDTH in your board config file. This is used to
create an array of {chip, ngpio} tuples that are used to determine the
width of a particular chip. For backwards compatibility it is assumed that
any chip not defined in CONFIG_SYS_I2C_PCA953X_WIDTH has 8 pins.

the read transfer is always active and SDHC DATA line is always active,

72c96a6802 tsec: Revert to setting TBICR_ANEG_ENABLE by default for SGMII
The following commit:

commit 46e91674fb
Author: Peter Tyser <ptyser@xes-inc.com>
Date:   Tue Nov 3 17:52:07 2009 -0600

    tsec: Force TBI PHY to 1000Mbps full duplex in SGMII mode

Removed setting Auto-Neg by default, however this is believed to be
proper default configuration for initialization of the TBI interface.

Instead we explicitly set CONFIG_TSEC_TBICR_SETTINGS for the
XPedite5370 & XPedite5500 boards that use a Broadcomm PHY which require
Auto-Neg to be disabled to function properly.

This addresses a breakage on the P2020 DS & MPC8572 DS boards when used
with an SGMII riser card.  We also remove setting
CONFIG_TSEC_TBICR_SETTINGS on the P1_P2_RDB family of boards as now the
default setting is sufficient for them.

Additionally, we clean up the code a bit to remove an unnecessary second
define.

This patch is a port of the work by Sudhakar Rajeshekhara in commit
ab3effbcad8851cc65dc5241a01c064d2030a3b2 of
git://arago-project.org/git/people/sandeep/u-boot-davinci.git.

The da850 UI board has on it an RMII PHY which can be used if the MDC line
to the MII PHY on the baseboard is disabled and the RMII PHY is enabled by
configuring the values of some GPIO pins on the IO expander of the UI board.
This patch implements disabling that line via GPIO2[6], configuring the UI
board's IO expander and setting only the pinmux settings that are needed for
RMII operation.

Tested on da850evm by adding a define for CONFIG_DRIVER_TI_EMAC_USE_RMII.

34bbb8fb46 cfi_flash: fix bug introduced while recent change to flash_get_size()
commit ec50a8e389
"cfi_flash: handle 'chip size exceeds address window' situation"
added 3rd argument to flash_get_size() but didn't fix all the
function calls from the board specific code. Many boards have
their own flash_get_size() definitions in the board code and
use them there, but some boards (e.g. tqm834x, tqm85xx, pdm360ng)
use flash_get_size() from the cfi_flash.c driver.

The bug shows up if the value of the "max_size" argument (which
is not defined when calling the function with two arguments)
happens to be less than "info->size". In this case on the
affected boards we end up with a bank of reduced size and
in the worst case might even be not able to update U-Boot or
to boot the kernel from flash:

=> fli

Bank # 1: CFI conformant FLASH (32 x 16)  Size: 0 kB in 1 Sectors
  AMD Standard command set, Manufacturer ID: 0x01, Device ID: 0x227E
  Erase timeout: 4096 ms, write timeout: 1 ms
  Buffer write timeout: 3 ms, buffer size: 64 bytes

  Sector Start Addresses:
  F0000000   RO

Bank # 2: CFI conformant FLASH (32 x 16)  Size: 128 MB in 512 Sectors
  AMD Standard command set, Manufacturer ID: 0x01, Device ID: 0x227E
  Erase timeout: 4096 ms, write timeout: 1 ms
  Buffer write timeout: 3 ms, buffer size: 64 bytes

  Sector Start Addresses:
  F8000000        F8040000        F8080000        F80C0000        F8100000
  F8140000        F8180000        F81C0000        F8200000        F8240000
  ...

E.g., updating U-Boot is not possible now:

=> protect off ${u-boot_addr} +${u-boot_size}
Error: end address (0xf007ffff) not in flash!
Bad address format
=> era ${u-boot_addr} +${u-boot_size}
Error: end address (0xf007ffff) not in flash!
Bad address format

This patch removes the 3rd argument of flash_get_size() again
and sets "max_size" in the function itself instead of passing
it as a function argument.

which runs when the MPU is running at 600MHz will timeout in around
half the time when running at 1GHz. or the example where GCC 4.5
compiles with different optimization compared to GCC 4.4. use timer
to keep track of time elapse and we use an emperical number - 1sec
for a worst case timeout.  This should never happen, and is adequate

6d8962e814 Switch from archive libraries to partial linking
Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils.  As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".

This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.

The name of each former library archive is preserved except for
extensions which change from ".a" to ".o".  This commit updates
references accordingly where needed, in particular in some linker
scripts.

This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols.  Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

009884ae35 pci: Use intelligent indentation for CONFIG_PCI_SCAN_SHOW
When CONFIG_PCI_SCAN_SHOW is defined U-Boot prints out PCI devices as
they are found during bootup, eg:
  PCIE1: connected as Root Complex

        02:01.0 - 10b5:8518 - Bridge device

  PCIE2: connected as Root Complex
        0d:00.0 - 1957:0040 - Processor
  PCIE2: Bus 0c - 0d

This information is useful, but its difficult to determine the PCI bus
topology.  To things clearer, we can use indention to make it more
obvious how the PCI bus is organized.  For the example above, the
updated output with this change is:

  PCIE1: connected as Root Complex
    01:00.0     - 10b5:8518 - Bridge device
     02:01.0    - 10b5:8518 - Bridge device

       04:01.0  - 8086:1010 - Network controller
       04:01.1  - 8086:1010 - Network controller
     02:02.0    - 10b5:8518 - Bridge device

  PCIE2: connected as Root Complex
    0d:00.0     - 1957:0040 - Processor
  PCIE2: Bus 0c - 0d

In the examples above, an MPC8640 is connected to a PEX8518 PCIe switch
(01:00 and 02:0x), which is connected to another PEX8518 PCIe switch
(06:00 and 07:0x), which then connects to a MPC8572 processor (08:00).
Also, the MPC8640's PEX8518 PCIe switch is connected to a PCI ethernet
card (04:01) via a PEX8112 PCIe-to-PCI bridge (03:00).

a38d216eeb pci: Fix ordering of devices when CONFIG_PCI_SCAN_SHOW
Move the printing of PCI device information to before the PCI device is
configured.  This prevents the case where recursive scanning results in
the deepest devices being printed first.

This change also makes PCI lockups during enumeration easier to
diagnose since the device that is being configured is printed out prior
to configuration.  Previously, it was not possible to determine which
device caused the PCI lockup.

Original example:
  PCIE1: connected as Root Complex
        04:01.0 - 8086:1010 - Network controller
        04:01.1 - 8086:1010 - Network controller

983eb9d162 pci: Clean up PCI info when CONFIG_PCI_SCAN_SHOW
This change does the following:
- Removes the printing of the PCI interrupt line value.  This is
  normally set to 0 by U-Boot on bootup and is rarely used during
  everyday operation.

- Prints out the PCI function number of a device.  Previously a device
  with multiple functions would be printed identically 2 times, which is
  generally confusing.  For example, on an Intel 2 port gigabit Ethernet
  card the following was displayed:
    ...
    04  01  8086  1010  0200  00
    04  01  8086  1010  0200  00
    ...

- Prints a text description of each device's PCI class instead of the
  raw PCI class code.  The textual description makes it much easier to
  determine what devices are installed on a PCI bus.

- Changes the general formatting of the PCI device output.

4a1a06bc8b mmc: Add multi-block read support to the generic mmc driver
This patch adds multi-block read support for the generic MMC
driver. Large reads are broken into chunks of 65535 blocks to
ensure that the code works with controllers having a 16 bit block counter.

This patch results in a significant performance improvement.

Time to read a 45 MB file went from 36 seconds to 9 seconds on Overo

4df6689495 ARMV7: OMAP: I2C driver: Fix bug found in 37XX testing
On OMAP36/37XX the standard on chip pullups are not sufficient to
ensure proper i2c operation without external pullups or switching
to high speed mode and enabling special on chip pullups.

This is an issue for Beagle xM, which does not have external pullups
on the expansion board i2c lines.

The issue manifests itself as an AL (arbitration lost) error when
probing for a non-existent device (i.e. on a Beagle xM with no expansion
boards attached).  This issue does not occur on expansion boards that
include pullups or on Overo 37XX COM's since they include pull-ups.

This patch fixes the issue by checking for the AL bit in the i2c_probe
function.

ec50a8e389 cfi_flash: handle 'chip size exceeds address window' situation
On some boards we have flash mapped high in the address space with
considerably small window (say 0xFE000000 and 32MB). When we install
bigger chip (say 64MB) on such a board strange things happen
(flash_write() doesn't work at all, for ex). That's because cfi_flash
driver doesn't care about window size at all.
Of course, cleanest solution would probably be to just extend address
window to be able to map the whole flash but for legacy/compatibility
reasons some people prefer just truncate the flash size and never use
the upper part.
This patch adds an option for cfi_flash driver to handle this situation
properly. To achieve this we add the new function cfi_flash_bank_size()
which can be provided by the board code and weak-aliased to default
implementation that returns value from the CONFIG_SYS_FLASH_BANKS_SIZES
array if it's defined or 0 otherwise (the last case is added for
compatibility).
If non-zero flash bank size is provided and detected chip size is bigger
than provided address window size the warning will be displayed and
flash chip will be truncated.

Changed cfi_flash_bank_size() return type to unsigned long

09c83a45b7 ehci-hcd.c: fix hanging under higher load
This patch solves a problem with USB hanging under higher load on a
i.MX31 board.  It falls into class of typical USB problems and fixes:
if you don't understand the real cause, add a delay somewhere.

The problem appeared after introduction of ELF relocation, which
results in smaller code, which appears to run faster (probably because
it fits better in the cache); turning off the instruction cache,
adding debug printf()s and increasing the delay have all been found to
make the problem go away.

Moving the original "udelay(1)" up in the code to it's new place made
the problem appear much less frequently. Increasing the delay to 2
microseconds then made the code run reliably in all (hour-long) tests.
To be on the safe side, we set it to 5 microseconds here.
