81d21e98b0 ARM: config: USB: Tegra30/114: Fix EHCI timeout issue on "bootp"
Fix the timeout issue after running "bootp" command in u-boot
console. For example you see "EHCI timed out on TD- token=0x...".
TXFIFOTHRES bits of TXFILLTUNING register should be set to 0x10
after a controller reset and before RUN bit is set
(per technical reference manual).

0d79f4f490 ARM: tegra: Make cache line size SoC specific
Currently all Tegra SoCs are assumed to have 32 byte cache lines. This
isn't true for Tegra114, however, which uses 4 Cortex-A15 cores and
therefore uses a cache line size of 64 bytes. Move the cache line size
setting to the per-SoC common configuration file.

Add USB EHCI, storage and network support.

Tested on Tegra30 Cardhu, and Tegra114 Dalmore
platforms. All works well.

c44bb3a30f ARM: tegra: enable some CPU errata workarounds
Tegra20 has a Cortex A9 r1p1, and Tegra30 has a Cortex A9 r2p9. As such,
some CPU errata exist, and must be worked around.

These must be worked around in the bootloader, since in general, the
kernel (especially a multi-platform kernel) needs to support being
launched in non-secure mode (normal world), and hence may not be able
to write to the CP15 register to enable these workarounds.

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.

f01b631f7d Tegra30: Add/enable Cardhu build (T30 reference board)
This build is stripped down. It boots to the command prompt.
GPIO is the only peripheral supported. Others TBD.

include/configs/tegra-common.h now holds common config options
for Tegra SoCs.
