3eb90bad65 Generic udelay() with watchdog support
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().

06bffc6ea5 rm9200 lowevel_init: don't touch reserved/readonly registers
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.

7168eba729 rm9200 ethernet driver: board-specific quirk (csb337)
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.

b54384e3ba arm: timer and interrupt init rework
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

655b34a78a i2c: Create common default i2c_[set|get]_bus_speed() functions
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.

f93286397e Add support for a saving build objects in a separate directory.
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.

95f9dda216 Eliminate hard-coded address of Ethernet transfer buffer on at91rm9200
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).
