2009-12-05Generic udelay() with watchdog supportIngo van Lil
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>

2009-08-03rm9200 lowevel_init: don't touch reserved/readonly registersDavid Brownell
For some reason the AT91rm9200 lowlevel init writes to a bunch of reserved or read-only addresses. All the boards seem to define the value-to-be-written values as zero ... but they shouldn't actually be writing *anything* there. No documented erratum justifies these accesses. It looks like maybe some pre-release BDI-2000 setup code has been carried along by cargo cult programming since at least late 2004 (per GIT history). Here's a patch disabling what seems to be bogosity. Tested on a csb337; there were no behavioral changes.

2009-07-22rm9200 ethernet driver: board-specific quirk (csb337)David Brownell
CSB337 boards originally shipped with MicroMonitor, not U-Boot; and with a version using a different convention for recording Ethernet addresses than anyone else. To avoid breaking Linux when it uses U-Boot, have it use the same convention on that hardware.

2009-06-12arm: timer and interrupt init reworkJean-Christophe PLAGNIOL-VILLARD
actually the timer init use the interrupt_init as init callback which make the interrupt and timer implementation difficult to follow so now rename it as int timer_init(void) and use interrupt_init for interrupt btw also remane the corresponding file to the functionnality implemented as ixp arch implement two timer - one based on interrupt - so all the timer related code is moved to timer.c Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>

2009-06-12i2c: Create common default i2c_[set|get]_bus_speed() functionsPeter Tyser
New default, weak i2c_get_bus_speed() and i2c_set_bus_speed() functions replace a number of architecture-specific implementations. Also, providing default functions will allow all boards to enable CONFIG_I2C_CMD_TREE. This was previously not possible since the tree-form of the i2c command provides the ability to display and modify the i2c bus speed which requires i2c_[set|get]_bus_speed() to be present.

2009-04-28Replace __attribute references with __attribute__Peter Tyser
__attribute__ follows gcc's documented syntax and is generally more common than __attribute. This change is only asthetic and should not affect functionality. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>

2006-09-01Add support for a saving build objects in a separate directory.Marian Balakowicz
Modifications are based on the linux kernel approach and support two use cases: 1) Add O= to the make command line 'make O=/tmp/build all' 2) Set environement variable BUILD_DIR to point to the desired location 'export BUILD_DIR=/tmp/build' 'make' The second approach can also be used with a MAKEALL script 'export BUILD_DIR=/tmp/build' './MAKEALL' Command line 'O=' setting overrides BUILD_DIR environent variable. When none of the above methods is used the local build is performed and the object files are placed in the source directory.

2005-10-09Eliminate hard-coded address of Ethernet transfer buffer on at91rm9200Wolfgang Denk
Patch by Anders Larsen, 07 Oct 2005 The Atmel errata #11 states that the transfer buffer descriptor table must be aligned on a 16-word boundary. As it turned out, this is insufficient - it seems the table must be aligned on a boundary at least as large as the table itself (in Linux this is not an issue - the table is aligned on a PAGE_SIZE (4096) boundary).
