When changing LDO voltages we need to wait for the required amount of time
for the voltage to settle.
Also, as the timer is still not available when arch_cpu_init() is called, we
need to call it later at board_postclk_init() phase.

Since ROM may modify the LDO ramp up time according to fuse setting,
it is safer to reset the ramp up field to its default value of 00:
00: 64 cycles of 24MHz clock;
01: 128 cycles of 24MHz clock;
02: 256 cycles of 24MHz clock;
03: 512 cycles of 24MHz clock;

According to NOTE in strtoul(3), the errno must be zeroed before strtoul()
is called. Zero the errno. The NOTE reads as such:
Since strtoul() can legitimately return 0 or ULONG_MAX (ULLONG_MAX for
strtoull()) on both success and failure, the calling program should set
errno to 0 before the call, and then determine if an error occurred
by checking whether errno has a nonzero value after the call.

The pmic_init() function has the I2C or SPI bus number that is connected to the
PMIC.
Instead of passing I2C_PMIC, explicitly pass the I2C bus number via I2C_x
definition.
The motivation for doing this is to avoid people just doing a copy and paste
of I2C_PMIC into their board file when another I2C bus is actually used to
interface to their PMIC.
This also makes more obvious which is the I2C bus connected to the PMIC, without
having to search in the source code for the meaning of the 'I2C_PMIC' number.

- siemens boards: adapt for background color = white
- add boutcount feature for the siemens boards
store the bootcount in the environment, as we have no softreset
save registers on this hardware. Use therefore the CONFIG_BOOTCOUNT_ENV

- change spi mode from 3 to 0 for the lcd init
- add gpio pin for lcd reset with state 0 and add mdelay
- siemens boards: use own USB id's
- add dfu serial and device number for siemens boards
Add for the siemens boards the possibility to define in dfu mode,
the iSerialNumber and the bcdDevice fields in the USB Device
descriptor.
- fix upgrade mechanism based on bootcount
Correct location of saveenv and remove not active variable.
Add CONFIG_BOOT_RETRY_TIME and CONFIG_RESET_TO_RETRY to
reboot board in case of empty kernel partition. Without
these defines an empty kernel partition leads to an
abort of boot process and one remains in u-boot prompt.
- general cleanup of dxr2, pxm2 and rut boards
all:
* Remove net boot from bootcmd
Ping can cause a crash on boards without ethernet phy.
net_nfs command is used only for development
* Add reset at the end of bootcmd
In order to have an immediate reset of the boot when bootcmd
fails, add reset at the end of bootcmd.

* add nand_img_size

* update nand_img_size
* ddr3 timings updated with iocontrol property that can be
