c9fcb59d7d sf: Add bank address register writing support
This patch provides support to program a flash bank address
register.

extended/bank address register contains an information to access
the 4th byte addressing in 3-byte address mode.

reff' the spec for more details about bank addr register
in Page-63, Table 8.16

f866a46d6e mmc: report capacity for the selected partition
Enhance the MMC core to calculate the size of each MMC partition, and
update mmc->capacity whenever a partition is selected. This causes:

mmc dev 0 1 ; mmcinfo

... to report the size of the currently selected partition, rather than
always reporting the size of the user partition.

01b77353e4 fsl_esdhc: Do not clear interrupt status bits until data processed
After waiting for the command completion event, the interrupt status
bits, that occured to be set by that time, are cleared by writing them
back. It is supposed, that it should be command related bits (command
complete and may be command errors).

However, in some cases the DMA already completes by that time before
the full transaction completes. The corresponding DINT bit gets set
and then cleared before even entering the loop, waiting for data part
completion. That waiting loop never gets this bit set, causing the
operation to hang. This is reported to happen, for example, for write
operation of 1 sector to upper area (block #7400000) of SanDisk Ultra II
8GB card.

The solution could be to explicitly clear only command related interrupt
status bits. However, since subsequent processing does not rely on
any command bits state, it could be easier just to remove clearing
of any bits at that point, leaving them all until all data processing
completes. After that the whole register will be cleared at once.

Also, on occasion, interrupts masking moved to before writing the command,
just for the case there should be no chance of interrupt between the first
command and interrupts masking.

a586c0aa21 mmc write bug fix
This patch fixes a bug related to mmc writes.

When doing fatwrites on an SD-Card, MMC bus problems can occur. Depending
on the size of the file, "MMC0: Bus busy timeout!" is reported, resulting
in an SD-Card that is no longer responding.
It appears to be, that set_cluster can be called with a size being zero.
That can be with a file that has a size being an exact multiple
(including 0) of the clustersize, but also for files that are smaller than
the size of one cluster.
The same problem occurs if the "mmc write" command is given with a block
count being 0.

By adding a check for the block count being zero in mmc_write_blocks
(drivers/mmc.c), this problem is solved.

This patch adds support to both Faraday FUSBH200 and FOTG210,
the differences between Faraday EHCI and standard EHCI are
listed bellow:

1. The PORTSC starts at 0x30 instead of 0x44.
2. The CONFIGFLAG(0x40) is not only un-implemented, and
   also has its address space removed.
3. Faraday EHCI is a TDI design, but it doesn't
   compatible with the general TDI implementation
   found at both U-Boot and Linux.
4. The ISOC descriptors differ from standard EHCI in
   several ways. But since U-boot doesn't support ISOC,
   we don't have to worry about that.

There is at least one non-EHCI compliant controller (i.e. Faraday EHCI)
not only leave RESERVED and CONFIGFLAG registers un-implemented
but also has their address spaces removed.

As an result, the PORTSC register of Faraday EHCI always
starts from 0x30 instead of 0x44 in standard EHCI.

So that we'll need a weak-aliased function for abstraction.

1. The 'index' of ehci_submit_root() is not always > 0.

   e.g.
   While it gets invoked from usb_get_descriptor(),
   the 'index' is always a '0'. (See ch.9 of USB2.0)

2. The PORTSC register is not always required, and thus it
   should only report a port error when necessary.
   It would cause a port scan failure if the ehci_submit_root()
   always gets terminated by a port error.

4edcf0a3df usb: asix: Move software resets to basic_init
The ASIX driver calls a basic_init() function during get_info(), so that
not all initialization tasks need to be redone on every init().
Unfortunately, the most important one is still triggered too often: the
driver does a full port and MII reset on every asix_init(), requiring up
to several seconds to reestablish the link.

This patch confines that software reset into the asix_basic_init()
function so that it will only be executed once. This saves about a
second of boot time on systems using BOOTP.

Note: this patch was previously submitted many moons ago as:

   usb: usbeth: asix: Do a fast init if link already established

That patch seens to have been lost or forgotten, so this is a rebased
version. It is tested on snow with a Asix USB dongle (Cisco).

960187ffa1 ARM: OMAP: I2C: New read, write and probe functions
New i2c_read, i2c_write and i2c_probe functions, tested on OMAP4
(4430/60/70), OMAP5 (5430) and AM335X (3359); should work on older
OMAPs and derivatives as well. The only anticipated exception would
be the OMAP2420, which shall require driver modification.
- Rewritten i2c_read to operate correctly with all types of chips
  (old function could not read consistent data from some I2C slaves).
- Optimised i2c_write.
- New i2c_probe, performs write access vs read. The old probe could
  hang the system under certain conditions (e.g. unconfigured pads).
- The read/write/probe functions try to identify unconfigured bus.
- Status functions now read irqstatus_raw as per TRM guidelines
  (except for OMAP243X and OMAP34XX).
- Driver now supports up to I2C5 (OMAP5).

Note that the unaligned accesses are made when copying data to prefix[] on

avoided. All explicitly written code treats the data as u8[], so will never

bcb6e9023a net: fec_mxc: Add support for Vybrid VF610
This patch adds FEC support for Vybrid VF610 platform.

In function fec_open(), RCR register is only set as RGMII mode. But RCR
register should be set as RMII mode for VF610 platform.
This configuration is already done in fec_reg_setup(), so this piece of
code could just leave untouched the FEC_RCNTRL_RGMII / FEC_RCNTRL_RMII /
FEC_RCNTRL_MII_MODE bits.

1b393db587 tpm: Reorganize the I2C TPM driver
This patch does a similar code reogranzation from
  http://patchwork.ozlabs.org/patch/132179/
which is based on an old version of code (fdt support and bus selection
still not in). It merges this tidy-up on top of the recent code. It does
not make any logical change.

tpm.c implements the interface defined in tpm.h based on underlying
LPC or I2C TPM driver. tpm.c and the underlying driver communicate
throught tpm_private.h.

Note: Merging the LPC driver with tpm.c is left to future patches.
