Stephen Warren	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.

Tom Warren	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. Signed-off-by: Tom Warren <twarren@nvidia.com>	2013-01-16 13:40:08 -07:00
Tom Warren	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.
