CFI Flash is currently handled outside the mtd layer which makes it
a special case. Integrate it into mtd so that we get rid of this
special status.

so for simple 64bit memory rom(ds2401/ds2411/ds1990*) no need driver.
Based on linux implementation, cleaned and re-implement the master/slave
support to use the device/driver model correctly.

This patch adds framework support for PWM (pulse width modulation)
devices.
A new pwm can be registered from a hardware driver using
pwmchip_add(). It can then be requested from a client driver using
pwm_request(). A string is used as a unique identifier for the
pwms. It should usually be initialized by the hardware drivers
using dev_name(dev). The client API is the same as currently
in the Linux Kernel.

Patch by Haavard Skinnemoen, 06 Sep 2006
This is a first attempt at creating a common serial driver for Atmel
chips. For now, it supports the AT32AP7000 AVR32 chip, but it should
be possible to support AT91RM9200 and other ARM-based chips with some
minor modifications.
There's nothing fundamentally AVR32-specific in this driver, but it
does use some features which are currently only defined for the
AT32AP CPU port:
* pm_get_clock_freq: Obtain the clock frequency of a given domain
* gd->console_uart: A "struct device" containing information about
register mappings, gpio resources and clocks associated with the
UART device.
For more information about these features, please see the "AT32AP
CPU" patch.
Modifications are based on the linux kernel approach and
support two use cases:
1) Add O= to the make command line
'make O=/tmp/build all'
2) Set environement variable BUILD_DIR to point to the desired location
'export BUILD_DIR=/tmp/build'
'make'
The second approach can also be used with a MAKEALL script
'export BUILD_DIR=/tmp/build'
'./MAKEALL'
Command line 'O=' setting overrides BUILD_DIR environent variable.
When none of the above methods is used the local build is performed and
the object files are placed in the source directory.
