The mask does not really need to be updated with atomic operations and
the downside of losing races during transitions is not great (it is
not marked volatile, so those races are pretty wide open as it is).

Kernel under stress load, mixed MC reboot and sfupdate really
generates TSO packet with RST flag.
It will generate many TCP packets with RST flag set.
May be RST flag should be set in the last segment only, but it could be
dropped. So, it is safer to keep the flag in all packets to be sure that
connection is reset.

Original dts filenames were not changed, they're now wrappers over dts

GPIO addressing was changed: instead of one global /dev/gpioc0 there
are per-bank instances of /dev/gpiocX. Each bank has 32 pins so for
instance pin 121 on /dev/gpioc0 in old addressing scheme is now pin 25
on /dev/gpioc3
On Pandaboard serial console devices was changed from /dev/ttyu0 to
/dev/ttyu2 so you'll have to update /etc/ttys to get login prompt

readdir(3) always uses an exact multiple of DIRBLKSIZ, so few applications
were affected. This patch fixes this problem by reducing the size
of the directory read to an exact multiple of DIRBLKSIZ.

If BOARDNAME is defined (as is in the WANDBOARD configuration

Yes, it is ugly, that is why there is a big warning at the top.
It is, however, still much cleaner than the now 474-line shell

The SD card specification says that a block write or a block erase can take
up to 250ms to complete and thus, under some circumstances, the existent 2

This change fixes the sporadic controller timeout that happens on RPi and
RPi 2.

MODULE_VERSION() macros don't end up as .comm symbols, when all the
version fields are zero.
Normally, such symbols will end up in .bss, but for kernel module
version objects, this can lead to "garbage" version numbers.
Fix this by instructing the compiler to always put these structs in the
.data segment instead.

This is based on the patch sent by Alexander Fedorov with the following
fixes/improvements:
- Better error handling;
- Clock is derived from PLL6 (obtained from netbsd);
- No more unnecessary busy loops on interrupt handler;
- style(9) fixes and code cleanup.
I also want to thanks Martin Galvan who has sent an alternative
implementation with some interesting fixes.
Tested on CubieBoard2, Banana-Pi (thanks to netgate!) and Cubieboard1
(Pratik Singhal).
This is intended to pave the way for the upcoming GSoC work (and make
easier the build of images for the supported boards).

The replacement started at r283088 was necessarily incomplete without
replacing boolean_t with bool. This also involved cleaning some type
