Hi,
In linux-3.0.0-rc2, for smdk2416 board, the kernel crashes while
booting up. The boot log is listed below. By turning of usb support,
the kernel boots up. This issue was not observed in linux-2.6.39
stable.
Starting kernel ...
Uncompressing Linux... done, booting the kernel.
Linux version 3.

Can we get an overview of what these features are?
When I look at this specific code I cannot see anything that
the dmaengine does not already support or

The S3C_GPIO_PULL_UP macro value incorrectly maps to a reserved setting of GPIO
pull up/down registers on Exynos4 platform. Fix this incorrect mapping by adding
wrappers to the s3c_gpio_setpull_updown and s3c_gpio_getpull_updown functions.
