[U-Boot] [PATCH 0/5] siemens: update and cleanup code

[Samuel Egli]

This patch series provides a general update and clean up for siemens boards.

* Update DDR3 settings for dxr2 board. Provide DDR3 software leveling
  parameters for new engineering samples

* Add more flexible control of LEDs

* Cosmetic changes in dxr2 and pxm2

Samuel Egli (5):
  siemens: cosmetic: remove unused and rename defines
  siemens: update DDR3 parameters for dxr2
  siemens: add led cmd for flexible LED control
  siemens: change LED indication in DFU mode
  siemens: cosmetic: rename project_dir

[U-Boot] [PATCH 1/5] siemens: cosmetic: remove unused and rename defines

[Samuel Egli]

For dxr2 board DXR2_IOCTRL_VAL is set by data in EEPROM. In pxm2
board it does not make sense to have dxr2 as prefix. Replace it with
more meaningful DDR prefix.

[U-Boot] [PATCH 3/5] siemens: add led cmd for flexible LED control

[Samuel Egli]

 * remove setting LED in user button function.
   We want to decouple reading user button and setting LED. This
   two things need to be done independently.

 * led cmd can be used to control LEDs that are defined in board file
   having a led cmd, one can easily set LEDs in u-boot shell. For
   example bootcmd can be extended to disable status LED before
   loading kernel.

[U-Boot] [PATCH 4/5] siemens: change LED indication in DFU mode

[Samuel Egli]

In order to have the same LED indication like in another product
when ready for updating, enable only red led and disable status
LED when entering DFU mode.

The status LED is only switched off when defined in board file.
