Fix setsdupdate by adding missing 'usb start' command.
While at it also add USB start to setethupdate as doing it twice won't
hurt (e.g. it returns immediately only 'usb reset' does a full rescan).

In order to use the gpio commandline feature of U-Boot the pins
one wants to control must be muxed to GPIO.
Do that for Apalis pins GPIO[1:8] and for WAKE1_MICO.
This feature can be used as follows:
e.g. set GPIO1 to 1:
Apalis iMX6 # gpio set 36
gpio: pin 36 (gpio 36) value is 1
e.g. read the state of GPIO8:
Apalis iMX6 # gpio input 6
gpio: pin 6 (gpio 6) value is 1

In order to use the gpio commandline feature of U-Boot the pins
one wants to control must be muxed to GPIO.
Do that for all unused pins which in the default kernel device tree also gets
muxed to gpio for userspace use.
This feature can be used as follows:
e.g. change the LCD brightness signal from 0V to 3.3V:
Colibri iMX6 # gpio set 41
gpio: pin 41 (gpio 41) value is 1
e.g. read the state of gpio 111:
Colibri iMX6 # gpio input 111
gpio: pin 111 (gpio 111) value is 1

Out of reset EMI_ADDR22 is output and connected to GPIO01.
As we want to use GPIO01 as an output for backlight control
mux EMI_ADDR22 to a GPIO which by default is input.

Add an alias for the ESDHC0 which provides the standard MMC connection
on Colibri iMX6.
Add an alias for the ESDHC0/1 which provides the standard MMC/SD connection
on Apalis iMX6.

Enable OF system setup to add hardware revision and serial number
information to the device-tree in case a mainline Linux kernel with any
such is booted.
While at it default back to the regular 8 MB DFU data buffer size.

Enable optional raw initrd support to allow boot using an initrd.

Various U-Boot adoptions/extensions to MTD/NAND/UBI did not take buffer
alignment into account which led to failures of the following form:
ERROR: v7_dcache_inval_range - start address is not aligned - 0x1f7f0108
ERROR: v7_dcache_inval_range - stop address is not aligned - 0x1f7f1108

Fix build of configurations without the Toradex config block. Also
move away from the ifdefery through the file, but create a global
ifdef which distingush between the two variants on a global level.
|
|
The USB product ID's for the Colibri/Apalis family of Toradex can
be calculated by using the Toradex product ID (as provided by the
config block) plus a fixed offset of 0x4000.
|

Use the boot loader splash screen from WinCE, which maches positionwise
our wallpapers. Altough the logo is a 8-Bit indexed BMP as well, colors
looked odd at first on U-Boot. After converting to full RGB pallette
and coverting back to indexed BMP using imagemagick, the Logo showed
up properly.
$ convert tools/logos/toradex-rgb.bmp -type Palette -colors 256 \
-compress none -verbose BMP3:tools/logos/toradex.bmp

This fixes the following warning (and the runtime error reporting):
../common/image-fdt.c:491:4: warning: 'fdt_ret' may be used uninitialized in this function [-Wmaybe-uninitialized]

When there is no framebuffer allocated, e.g. no video environment
variable or an error during initialization, the framebuffer location
ends up to be NULL, in which case the fixup function calculates a
bogus memory size. Use the framebuffer size to make sure that memory
size is calculated right in any case.
|

Set board revision and Toradex product ID as device tree property.
This transfers the Toradex configblock information to Linux user-
space, where it can be read conviniently through the proc file
system files:
- /proc/device-tree/serial-number
- /proc/device-tree/toradex,board-rev
- /proc/device-tree/toradex,product-id
In case the Toradex config block is missing or corrupted, the
device tree properties won't be created by the boot loader and
hence those file won't exist in that case.
|
|
Use ft_system_setup to set Toradex specific device-tree properties.
At first, this is only the serial-number, which is using a property
which is about to be standardized in the binding documentation of
the Linux kernel.
|
|
Move setting of environment variables to common code. This prepares
for further enhancements which will enhance the device tree with
module specific information from the configblock.
|

CONFIG_TRDX_CMD_IMX_MFGR in menu 'ARM architecture'
While at it remove unused include g_dnl.h

This uses the tools/logos/toradex.bmp instead of the default
tux logo and places it centered on screen.
While at it group the display releated variables together.
|
|
In U-Boot use the following display outputs a:
- Test the panel environment variable and if set use it
- Use HDMI if connected
- Use parallel output otherwise configured for VGA 640x480
The following strings can be set for the panel variable:
HDMI vga-rgb wvga-rgb
|
|
The ipu has two display interfaces. Make the used one a parameter
in struct display_info_t instead of using unconditionally DI0.
|
|
|
|
|
|
Swap the order of the Toradex factory configuration block location in
respect to the U-Boot environment. This to again be in-line with
mainline.
Move the Toradex factory configuration block to a 3 MB offset.

Add consoleblank=0 to disable console blanking by default. To use
initramfs without the need of creating a U-Boot image using mkimage,
enable CONFIG_SUPPORT_RAW_INITRD too.
|
|
Rename the serial loader boot mode to "serial". Also add an alias
for the ESDHC1 controller, which provides the standard MMC connection
for the Colibri SO-DIMM default pinout.
|
|
Some functionality is repetitve accross the boards. This creates
a common place for U-Boot functions which need to be implemented
similarly for all Toradex modules.
|
|
Add IOMUX for the pad used as USB pen. This needs to be driven low for
the Iris and Viola boards where it is pulled up high by default. This is
required for the USB host functionality to work on these boards. Use the
board specific weak initialisation function, to drive the pin low which
would be called on "usb start".

The serial_mxc UART can use DTE and DCE mode (i.e End device vs. modem).
This adds DTE mode capability to the driver.
In order to switch from the default DCE to DTE mode define CONFIG_MXC_UART_DTE.

Cleanup various whitespaces throughout its configuration file.
|
|
Fix setupdate handling.
While at it also fix using asix_mac rather than igb_mac on Colibri T30.
|
|
Fix comment in write_trdx_cfg_block_to_nand to actually indicate it
writing the config block to NAND.
|

Add missing new line in tegra_pcie_board_init.
|

Migrate Colibri T20 to U-Boot 2015.04.
|
|
Integrate 16-bit BCH ECC handling required e.g. for the latest NAND
parts assembled on Colibri T20.
|
|
Fix PIO read_byte() implementation not only used for the legacy READ ID
but also the PARAM command now required for proper ONFI detection.
This fix is inspired by Lucas Stach's Linux Tegra NAND driver of late.
While at it also disable subpage writes.
|
|
Add I2C support in order to subsequently allow disabling the PMIC sleep
mode on low supply voltage.
|
|
Add LCD display support defaulting to VESA VGA resolution. Different
resolutions configurable via device-tree.
|
|
Use toradex,colibri_t20 as the device-tree compatible node value rather
than toradex,t20 in accordance to our Apalis/Colibri T30 products.
|

Use the proposed format to transport the device's serial number
to the kernel:
http://www.spinics.net/lists/devicetree/msg76756.html
|
|
Also, the kernel argument has been renamed (to fec.macaddr) and uses
a different format (0x00,0x2d...). The FEC ethernet address is assigned
through device tree nowadays. Hence remove the old argument "fec_mac"
without replacement.

Add GPIO's typically required for display handling such as GPIO 45
(SO-DIMM 71, BL_ON) or GPIO 22 (SO-DIMM 59, PWM<A> for backlight).
