* 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>
* Add support for Eukrea CPUAT91 SBCTom Rix2009-10-13-2/+252
| | | | | | | | | CPUAT91 is built around Atmel's AT91RM9200 and has up to 16MB of NOR flash, up to 128MB of SDRAM, and includes a Micrel KS8721 PHY in RMII mode. Signed-off-by: Eric Benard <eric@eukrea.com> Signed-off-by: Tom Rix <Tom.Rix@windriver.com>
* rm9200 lowevel_init: don't touch reserved/readonly registersDavid Brownell2009-08-03-12/+2
| | | | | | | | | | | | | | | | | | | 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.

* rm9200 ethernet driver: board-specific quirk (csb337)David Brownell2009-07-22-4/+18
| | | | | | | | | | | 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.

* arm: timer and interrupt init reworkJean-Christophe PLAGNIOL-VILLARD2009-06-12-2/+2
| | | | | | | | | | | | | | 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>

* i2c: Create common default i2c_[set|get]_bus_speed() functionsPeter Tyser2009-06-12-10/+0
| | | | | | | | | | | | | 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.

* Replace __attribute references with __attribute__Peter Tyser2009-04-28-2/+3
| | | | | | | | __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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | 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).
