[U-Boot] [PATCH v1 0/5] arm, am33xx: update for the am33xx based siemens boards

[Heiko Schocher]

Patch 1 introduces bootcount support for the 3 siemens boards. As there
is no other possibility on this boards, the bootcounter is stored in the
environment. To prevent a "saveenv" on all reboots, a "upgrade_available"
U-Boot Environment variable is introduced.

Patch 2 makes the enabling of the RTC32K OSC configurable, as
on the dxr2 board it is not used, and
http://www.denx.de/wiki/view/U-Boot/DesignPrinciples#2_Keep_it_Fast
says not enable things not used ...

Patch 3 adds an option to set the iSerialNumber board specific, which
is used on the 3 siemens boards.

Patch 4 adds an option to set the bcdDevice number board specific, which
is used on the 3 siemens boards.

Patch 5 contains a lot of updates for the siemens boards, see commit
message for detailed information.

[U-Boot] [PATCH v1 1/5] bootcount: store bootcount var in environment

[Heiko Schocher]

If no softreset save registers are found on the hardware
"bootcount" is stored in the environment. To prevent a
saveenv on all reboots, the environment variable
"upgrade_available" is introduced. If "upgrade_available" is
0, "bootcount" is always 0 therefore no need to save the
environment on u-boot boot, if "upgrade_available" is 1 "bootcount"
is incremented in the environment and environment gets written
on u-boot start.
So the Userspace Applikation must set the "upgrade_available"
and "bootcount" variable to 0 (for example with fw_setenv),
if a boot was successfully.

Just curious... why not save the bootcount in a RTC scratchpad register?
IIRC that's persistent across boot cycles if there's battery backup.

[U-Boot] [PATCH v1 2/5] arm, am33x: make RTC32K OSC enable configurable

[Heiko Schocher]

As
http://www.denx.de/wiki/view/U-Boot/DesignPrinciples#2_Keep_it_Fast
states:
"Initialize devices only when they are needed within U-Boot"

enable the RTC32K OSC only, if CONFIG_SPL_AM33XX_ENABLE_RTC32K_OSC is
enabled. Enable this in ti_am335x_common.h, so all boards in mainline
should work as before.

[U-Boot] [PATCH v1 3/5] usb, g_dnl: make iSerialNumber board configurable

[Heiko Schocher]

add the possibility to set the iSerialNumber board specific.
Therefore the CONFIG_G_DNL_SERIAL_STRING is introduced, which
defines the maximum length of the iSerialNumber string.
The new function g_dnl_set_serialnumber() must called from
g_dnl_bind_fixup(), to setup the iSerialNumber string.

I don't like the #if defined preprocessor directives here. The g_dnl.c
code is a generic code, to "glue" all functions together.

I think that #if defined(CONFIG_G_DNL_SERIAL_STRING) can be easily
removed, since the iSerialNumber is a valid member of struct
usb_descriptor.

In my opinion, instead of defining #ifdefs, we can define some "default"
iSerialNumber for all devices.

Then this value can be overridden by board when needed by call to
g_dnl_set_serialnumber() function

Ok! How would look like the default serial number?

Ok. Will change it in this direction, thanks for the review!

Some devices have default serial number set to 0 or 0xFFFFFFFF. Maybe we
can start with the 0 value?

No problem. You are welcome.

[U-Boot] [PATCH v1 4/5] usb, g_dnl: make bcdDevice value configurable

[Heiko Schocher]

add the possibility to set the bcdDevice number board specific.
Therefore the weak function g_dnl_get_board_bcd_device_number()
is introduced. Used on the siemens boards.

[U-Boot] [PATCH v1 5/5] arm, am335x: update for the siemens boards

[Heiko Schocher]

From: Samuel Egli <samuel.egli@siemens.com>

- dxr2: define unused pins as input
- do not enable RTC32K OSC on dxr2 board
- update default environment
  - add splashpos=m,m to default environment, so splash screen is always
    centered.
  - adapt environment for bootcount feature
  - add altbootcmd to default environment
- rut: SPL add early reset pulse for eth-phy, maXTouch and display
- rut: display timing aenderungen
- 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
  bootcount driver.
- 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.

  rut:
   * add nand_img_size

  dxr2:
   * update nand_img_size

   * ddr3 timings updated with iocontrol property that can be
     modified via eeprom. New default parameters from software
     leveling with draco ES2.
