2009-05-18i.MX31: Add support for the CPLD on PDK Debug board.Magnus Lilja
The i.MX31 PDK consists of several boards, one of them is a debug board containing a CPLD which controls some debug leds, switch buttons, an interrupt chip and an Ethernet controller. This patch adds support for detecting if the PDK board is present (during boot) and adds the interrupt chip to the kernel.

2009-05-07mx31: remove gpio_request calls from iomux codeValentin Longchamp
Since iomux code is not directly related to gpio on mx31, the calls to gpio_request are removed from iomux.c file. These calls have to be done in platform initialization files. The name of the singe pin call for iomux is also changed to mxc_iomux_alloc_pin. Signed-off-by: Valentin Longchamp <valentin.longchamp@epfl.ch> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

2009-03-19[ARM] pass reboot command line to arch_reset()Russell King
OMAP wishes to pass state to the boot loader upon reboot in order to instruct it whether to wait for USB-based reflashing or not. There is already a facility to do this via the reboot() syscall, except we ignore the string passed to machine_restart(). This patch fixes things to pass this string to arch_reset(). This means that we keep the reboot mode limited to telling the kernel _how_ to perform the reboot which should be independent of what we request the boot loader to do.
