30a43cc2ae Bugfix in I2C initialisation on S3C2400.
If the bus is blocked because of a previously interrupted
transfer, up to eleven clocks are generated on the I2CSCL
line to complete the transfer and to free the bus.
With this fix pin I2CSCL (PG6) is really configured as GPIO
so the clock pulses are really generated.

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).

9c998aa831 Fix low-level OHCI transfers for ARM920t and MPC5xxx
A new, Windows compatible init sequence was also backported from Linux 2.6,
but disabled with #undef NEW_INIT_SEQ as it wouldn't change the behaviour
of the memopry sticks we tested. Maybe it's not relevant for mass storage
devices. For recerence, see file common/usb.c, function usb_new_device(),
section #ifdef NEW_INIT_SEQ.

f6e20fc6ca Patch by Anders Larsen, 09 Jan 2004:
ARM memory layout fixes: the abort-stack is now set up in the
correct RAM area, and the BSS is zeroed out as it should be.

Furthermore, the magic variables 'armboot_end' and 'armboot_end_data'
of the linker scripts are replaced by '__bss_start' and '_end',
resp., which is a further step to eliminate unnecessary differences
between the implementation of the CPU architectures.
