d08b9e9c7e tegra: remove IRDA pinmux synonym
IRDA is a synonym for UARTB in tegra pinmux, remove all usage of this
synonym and replace with UARTB to disambiguate.

bb1e7cde62 Tegra30: I2C: Enable I2C driver on Cardhu
Tested all 5 'buses', i2c probe enumerates device addresses on all
but dev 4 (I2C4) [no devices on that bus on my Cardhu].

Note that this uses the extant tegra_i2c.c driver w/o modification.

083bbbbe77 Tegra30: fdt: Update DT files with I2C info for T30/Cardhu
Note that T30 does not have a separate/different DVC (power I2C)
controller like T20 - all 5 I2C controllers are identical, but
DVC_I2C is still used to designate the controller intended for
power control (PWR_I2C in the schematics). On Cardhu, it's used
to access the PMU and EEPROM, as well as the audio codec, temp
sensor, and fuel gauge devices from the OS.

0c5587549b video: tegra: Update line length to match resolution
Instead of storing the computed line length in a local variable, store
it in the global lcd_line_length variable to make sure the LCD subsystem
can properly draw content for the display resolution.

This probably wasn't noticed yet because the only board where LCD
support is currently enabled is Seaboard, which runs at a 1366x768
resolution. As it happens this is the maximum resolution supported and
also the default that is used to initialize the framebuffer before the
configuration from DT is available.

3567e4ef11 MIPS: qemu-mips: add '-M mips' switch to the example usage command
Using the example command from the README file does
not work as expected. qemu shows a text similar to
the one below and it hangs.

    $ qemu-system-mips -L . -nographic
    Could not open option rom 'pxe-pcnet.rom': No such file or directory
    qemu-system-mips: pci_add_option_rom: failed to find romfile "vgabios-cirrus.bin"
    qemu: terminating on signal 15 from pid 19726

This happens because qemu emulates a Malta board by
default if the machine type is not defined explicitely
on the command line.

For a working test, the '-M mips' switch is required:

    $ qemu-system-mips -M mips -L . -nographic
    Could not open option rom 'vgabios.bin': No such file or directory

The 'Limitations & comments' section refers to the
'-m mips' switch which is not valid. The '-m' switch
can be used for setting the virtual RAM size:

    $qemu-system-mips --help | grep '^-m '
    -m megs         set virtual RAM size to megs MB [default=128]

The correct switch for specifying the machine type is '-M'.

broke the check that allowed U-Boot to display 8 bpp BMPs on a 16

it originally had.
To avoid future confusion, the check has also been rephrased to make
its meaning clear.

acbb4457ab mx6qsabresd: Fix booting the kernel from SDHC3
Since commit de7d02aeb (mx6qsabresd: add usdhc2 and usdhc4 support)
SDHC3 device node is no longer 0, which breaks loading a uImage from SDHC3.

Fix it by adapting the default environment to use CONFIG_SYS_MMC_ENV_DEV as the
correct mmc node for loading the kernel from.

While at it, go back to using SDHC3 as the default mmc, since we have Yocto
images that generate an SD card containing U-boot,kernel and rootfs, so it is
more convenient to keep using SDHC3 as it was originally.
