5f5ec09bfb Determine kernel load address dynamically from u-boot memory map.
The generic ELF loading code maps the kernel into low memory
by subtracting KERN_BASE.  So the copyin/copyout/readin functions
are always called with low addresses.  This code finds the largest
DRAM block from the U-Boot memory map and adds that base to
the addresses.

In particular, this fixes ubldr on AM3358, which has DRAM
mapped to 0x80000000 at power-on.

c3a9b90973 Access the device tree blob via copyin/copyout.
The code previously assumed that copyin/copyout did no
address translation and that the device tree blob could
be manipulated in-place (with only a few adjustments for
the ELF loader offset).  This isn't possible on all platforms,
so the revised code uses copyout() to copy the device tree
blob into a heap-allocated buffer and then updates the
device tree with copyout().  This isn't ideal, since it
bloats the loader memory usage, but seems the only feasible
approach (short of rewriting all of the fdt manipulation
routines).

This change is specific to BeagleBone; I need to figure out how to

5bf877dace Don't call strcmp with a NULL pointer.
In particular, on the AM335x, which comes up with no memory
mapped to low addresses, dereferencing the NULL causes a crash.

04296b6f18 Improve device tree blob (DTB) handling in loader(8).
Enable using the statically embedded blob from the kernel, if present. The KLD
loaded DTB takes precedence, but they are both recognized and handled in the
same way.

0ed948780c Initial support of loader(8) for ARM machines running U-Boot.
This uses the common U-Boot support lib (sys/boot/uboot, already used on
FreeBSD/powerpc), and assumes the underlying firmware has the modern API for
stand-alone apps enabled in the config (CONFIG_API).

Only netbooting is supported at the moment.

042df2e2da Enable GCC stack protection (aka Propolice) for userland:
- It is opt-out for now so as to give it maximum testing, but it may be
  turned opt-in for stable branches depending on the consensus.  You
  can turn it off with WITHOUT_SSP.
- WITHOUT_SSP was previously used to disable the build of GNU libssp.
  It is harmless to steal the knob as SSP symbols have been provided
  by libc for a long time, GNU libssp should not have been much used.
- SSP is disabled in a few corners such as system bootstrap programs
  (sys/boot), process bootstrap code (rtld, csu) and SSP symbols themselves.
- It should be safe to use -fstack-protector-all to build world, however
  libc will be automatically downgraded to -fstack-protector because it
  breaks rtld otherwise.
- This option is unavailable on ia64.

Enable GCC stack protection (aka Propolice) for kernel:
- It is opt-out for now so as to give it maximum testing.
- Do not compile your kernel with -fstack-protector-all, it won't work.

7572ed5a08 Eliminate artificial increasing of 'netdev_opens' counter in loader's net_open().
This was introduced as a workaround long time ago for some Alpha firmware
(which is now gone), and actually prevented net_close() to ever be
called.

Certain firmwares (U-Boot) need local shutdown operations to be performed on a
network controller upon transaction end: such platform-specific hooks are
supposed to be called via netif_close() (from within net_close()).

This change effectively reverts the following CVS commit:

    sys/boot/common/dev_net.c

    revision 1.7
    date: 2000/05/13 15:40:46;  author: dfr;  state: Exp;  lines: +2 -1
    Only probe network settings on the first open of the network device.
    The alpha firmware takes a seriously long time to open the network device
    the first time.

Also suppress excessive output while netbooting via loader, unless debugging.

While there, make sys/boot/uboot more style(9) compliant.
