* Nomadik: fix reset_timer()Alessandro Rubini2010-04-03-3/+12
| | | | | | | | | | | | Previous code was failing when reading back the timer less than 400us after resetting it. This lead nand operations to incorrectly timeout any now and then. Moreover, writing the load register isn't immediately reflected in the value register. We must wait for a clock edge, so read_timer now waits for the value to change at least once, otherwise nand operation would timeout anyways (though less frequently).

* Generic udelay() with watchdog supportIngo van Lil2009-12-05-1/+1
| | | | | | | | | | | | | According to the PPC reference implementation the udelay() function is responsible for resetting the watchdog timer as frequently as needed. Most other architectures do not meet that requirement, so long-running operations might result in a watchdog reset. This patch adds a generic udelay() function which takes care of resetting the watchdog before calling an architecture-specific __udelay(). Signed-off-by: Ingo van Lil <inguin@gmx.de>
* arm nomadik: use 1000 as HZ value and rewrite timer codeAlessandro Rubini2009-07-06-139/+27
| | | | | | | | | | | | This sets CONFIG_SYS_HZ to 1000 as required, and completely rewrites timer code, which is now both correct and much smaller. Unused functions like udelay_masked() have been removed as no driver uses them, even the ones that are not currently active for this board. mtu.h is copied literally from the kernel sources.

* Initial support for Nomadik 8815 development boardAlessandro Rubini2009-01-24-0/+183
The NMDK8815 board is distributed by ST Microelectornics. Other (proprietary) code must be run to unlock the CPU before U-Boot runs. doc/README.nmdk8815 outlines the boot sequence. This is the initial port, with basic infrastructure and a working serial port.
