Oleksij Rempel fbf9d87633 cfi_flash: add shift option for some cfi memory chips
Many cfi chips support 16 and 8 bit modes. Most important
difference is use of so called "Q15/A-1" pin. In 16bit mode this
pin is used for data IO. In 8bit mode, it is an address input
which add one more least significant bit (LSB). In this case
we should shift all adresses by one:
For example 0xaa << 1 = 0x154

Sascha Hauer d817fb6b86 of: populate devices based on "simple-bus" property
We used to populate the devices from the devicetree based on the
presence of the 'reg' property. This is incorrect since this only
allows us to probe devices with resources.
Instead use the 'simple-bus' property to see if we have iterate
deeper. This also registers devices with their buses as parents.

This patch separates out the "generic" memory
segment registration function (of_add_memory_bank())
from of_add_memory().
The MIPS architecture has different view on memory
resources than the ARM and PPC architectures
so the "generic" of_add_memory_bank() is
unusable for the MIPS architecture.
We can add MIPS-specific of_add_memory_bank()
into arch/mips code.

Juergen Beisert 6a5e4f0c89 MCI/MXS: fix signed/unsigned mismatch
Using the MXS MCI driver with an eight bit capable eMMC results into the
'devinfo' message the interface uses '0' bits for data transfer:

 barebox:/ devinfo mxs_mci0
 resources:
 num   : 0
 start : 0x80034000
 size  : 0x00002000
 driver: mxs_mci

   Min. bus clock: 1476 Hz
   Max. bus clock: 48000000 Hz
   Current bus clock: 24000000 Hz
   Bus width: 0 bit

The eight bit interface width is stored internally as value '2'. And a two bit
'2' ends up into 0xfffffffe when used as an array index. Using an unsigned
field instead fixes this issue:

 barebox:/ devinfo mxs_mci0
 resources:

Sascha Hauer 7f63c0a246 Add initial pinctrl support
This is a massively stripped down pinctrl support. The upper API
consists of only of:

int pinctrl_select_state(struct device_d *dev, const char *state);

This is used to setup the pinmux for a device to a certain state.
This function normally does not need to be called manually. The
device core will setup the default state before probing a device.

The pinctrl core has the job of handling the devicetree. It parses
the pinctrl phandles for a device from devicetree, finds the correct
pinctrl device and calls its set_state callback with the pinctrl
setup device node.

The simplicity of this pinctrl framework comes from the fact that
we:

- Limit usage to devicetree only for now. For non devicetree use the
  old legacy SoC specific APIs still can be used.
- Do not parse the devicetree into internal data structures which
  are used by the drivers later. This adds the overhead that we
  may parse the devicetree multiple times for more dynamic setups,
  but on the other hand we do not need to parse devices from the
  devicetree we don't use in barebox
- Do not detect resource conflicts. Since the framework mainly is
  a devicetree parser this would be hard to implement. It should
  be easy for board maintainers to avoid resource conflicts though.

Eric Bénard 4c2bdc8728 nand_base: detect more ONFI flash
if the flash has a known type, the ONFI detection won't occur
and thus we may not detect the right parameters.
By testing both namd and pagesize, as done in the kernel, we
can detect ONFI flash with know IDs.

As an example on an i.MX53 board :
- without the patch :
NAND device: Manufacturer ID: 0x2c, Chip ID: 0xd3
(Micron NAND 1GiB 3,3V 8-bit), page size: 4096, OOB size: 128

- with the patch :
ONFI flash detected ... ONFI param page 0 valid
NAND device: Manufacturer ID: 0x2c, Chip ID: 0xd3
(Micron MT29F8G08ABACAWP), page size: 4096, OOB size: 224

in the first case the OOB size is wrong.

Sascha Hauer 87eebfe966 clk: Add is_enabled callback
This allows us to better detect whether a clk is enabled or not.

- If we can ask a clk, ask it. If it's enabled, go on and ask parents
- If we can't ask it, but it can be enabled, depend on the enable_count.
  if it's positive, go on and ask parents
- If we can't ask it and it cannot be enabled, assume it is enabled
  and ask parents.

This makes the CLK_ALWAYS_ENABLED unnecessary, since the fixed clk now
always returns 1 in its is_enabled callback.

Sascha Hauer 545453ddae mtd: nand: Add command to generate a flash BBT
With 2k NAND flashes the data layout in memory is not what is
written on the flash device. This leads to the result that the
factory provided bad block markers are not recognized correctly.

To preserve the factory bad block information the i.MX NAND driver
will not scan for the bad blocks itself when there is no flash based
bbt available, because the mtd layer would do so based on wrong
information. Instead, a new command is introduced which allows to
manually create a flash bbt based on the correct information.

As this command is tightly coupled to mtd and the i.MX NAND driver
the command is placed under drivers/mtd/nand/ instead of commands/
where a command normally belongs to.

This makes the oftree, of_node and of_property commands independent
of devicetree device support since being able to manipulate
devicetrees has nothing to do with probing devices from the devicetree.

Sascha Hauer b50c00a61d of: remove allnodes list
The allnodes list makes it hard to handle multiple devicetrees. Having
a list to iterate over all nodes of a tree is still good to have though.
This patch uses the list_head of the root node as the head of the list.
This way the root node is no longer part of the list, but when iterating
over a tree the root node is not interesting anyway.

Sascha Hauer 10473b33d7 mtd: always write page when oob is given
Since recently we check for the page being written for not being
empty and do not actually write it when it is. This fails for a
freshly created flash bad block table when all blocks are good.
In this case the bbt code will try to write an empty page, but
with the BBT marker in OOB. This page never gets written, so the
BBT code will not find a bad block table during next start up and
writes it again. Fix this by checking if we want to write OOB data,
if we do, then write the page, even if the data is empty.

Sascha Hauer 22d747e264 mtd: nand: do not write empty pages
Do not write pages which only contain 0xff. UBI expects pages which
seem empty to be writable. This got lost with:

| commit 3139c3e9a6
| Author: Sascha Hauer <s.hauer@pengutronix.de>
| Date:   Thu Nov 29 11:16:40 2012 +0100
|
|    mtd core: call driver write function with complete buffer
|
|    mtd->write is supposed to loop around pages internally, no need
|    to do this in mtd_write. This fixes a huge write performance drop
|    with the m25p80 driver when it was converted to a mtd driver recently.
|    Since mtd->writesize is 1 for this driver mtd_write ended up doing
|    single byte writes on the flash.

Introduce mtd_all_ff as a global function since UBI currently has its own
implementation.
