The RedBoot boot loader writes flash partition tables containing native
byte sex 32 bit values. When booting an opposite byte sex kernel (e.g. an
LE kernel from BE RedBoot) the current MTD driver fails to handle the
partition table and therefore is unable to generate the correct partition
map for the flash.
So far as I am aware this problem is ARM specific, because only ARM
supports software change of the CPU (memory system) byte sex, however the
partition table parsing is in generic MTD code. The patch below has been
tested on NSLU2 (an IXP4XX based system) with a patch,
10-ixp4xx-copy-from.patch (submitted to linux-arm-kernel - it's ARM
specific) required to make the maps/ixp4xx.c driver work with an LE kernel.
Builds of the patched system are in the 'unstable' release of OpenSlug and
UcSlugC available from www.nslu2-linux.org. These builds are BE, the
archives at www.nslu2-linux.org and www.handhelds.org (see
monotone.vanille.de) can be built LE (currently DISTRO targets
nslu-ltu.conf for LE thumb uclibc (32 bit kernel) and nslu2-lau.conf,
nslu2-lag.conf for LE arm uclibc/glibc) and this patch has been tested
extensively will both BE and LE systems on the NSLU2 (including swapping
between BE and LE by reflashing from both RedBoot and Linux).
The patch recognises that the FIS directory (the partition table) is
byte-reversed by examining the partition table size, which is known to be
one erase block (this is an assumption made elsewhere in redboot.c). If
the size matches the erase block after byte swapping the value then
byte-reversal is assumed, if not no further action is taken. The patched
code is fail safe; should redboot.c be changed to support a partition table
with a modified size field the test will fail and the partition table will
be assumed to have the host byte sex.
If byte-reversal is detected the patch byte swaps the remainder of the 32
bit fields in the copy of the table; this copy is then used to set up the
MTD partition map.

ACPI is initialized very early on x86-64, before the DMI code is
initialized. This means it would often discover a 0 year and then turn
off ACPI because it thought the BIOS was too old. Some systems don't
boot without ACPI so this was a problem.
I have a full fix by adding new very early DMI detection, but it needs
more testing before it can be merged. For 2.6.16 let's just turn the
check off. It never made much sense anyways because there are no x86-64
systems older than 2002 or so and they generally all have working ACPI.

who forgot to set it make it depend on CONFIG_EMBEDDED. x86-64 had
this change before and it's a good thing.

which causes the controller to return R_ERR on DMA activate FIS if the

implements the workaround.
This errata results in lock up and doesn't trigger if m15w workaround
is in effect. We stopped applying m15w to 3512 and 3114 in 2.6.14-rc1

EGA boards suck: they mostly have write-only registers. This is
particularly problematic for the overflow register: for being able to write
to it, we would have to handle vertical sync & such too, which (I'd say)
would potentially break a lot of configurations. Instead, just disabling
vertical resize for EGA boards is just nice enough (horizontal resize still
works).

tty_schedule_flip() would schedule a thread that would call flush_to_ldisc().
If tty_buffer_request_room() gets called prior to that thread running --
which is likely in this loop in hvc_poll(), it would set the active flag
in the tty buffer and consequently flush_to_ldisc() would ignore it.
The result is that input on the hvc console is not processed.
This fix calls tty_flip_buffer_push (and flags the tty as
"low_latency"). The push to the ldisc thus happens synchronously.
