For 32-bit SDRAM systems, enable D16 to D31 in the PIO controller.
Otherwise they read back as 0xffff.
Shave 8 bytes from the object size by using AT91C_BASE_PIOA directly
and by not assigning PIO_BSR to 0 in the DBGU init. That's a nop in
two ways (everything defaults to peripheral A, and writing 0 changes
nothing).
Many places used #define FOO ((unsigned int) 0x23) where a simpler
#define FOO 0x23u would have sufficed. This practice is overly
verbose and has the disadvantage that you can't say
#if FOO == BAR
#endif
because the extra "unsigned int" tokens choke cpp's little brain.
Migrate to the latter style to allow use in preprocessor statements.
The two are the same semantically anyway in a C context (at least for
the uses they are put to presently, C gurus can explain to me how they
differ).
working on.
1) Make it possible to configure interfaces with certain characters in
their names that aren't valid in shell variables. Currently supported
characters are ".-/+". They are converted into '_' characters.
2) Replace nearly all eval statements in network.subr with a new
function get_if_var which substitues an interface name (after the
translations above) for "IF" in a variable name.
3) Fix list_net_interfaces() in the nodhcp case.
4) Allow the administrator to specify if dhclient should be started
when /etc/rc.d/netif configures the interface or only by devd.
This can be set on both a per interface and system wide basis.

via xmodem to the DBGU port when the AT91 comes up in recovery mode.
The recovery loader will then load your program via xmodem into SDRAM
at 1MB which can do its things. It needs to be tweaked to the
specific board one is using, but it fits in < 1kB (all of Atmel's ARM
products have at least 8kb of SRAM that I can tell, so this should
work for them all).
Parts of this code were provided by Kwikbyte with copyright
specifically disclaimed. I heavily modified it to act as a recovery
loader (before it was a bootstrap loader) and to optimize for size
(before I started the size was closer to 8k).
Bootstrap loaders for SPI and IIC to follow.

add assertions blocking the creation of managed mappings within the clean
