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.
o This is disabled by default for now, and can be enabled using WITH_FDT at
build time.
o Tested with ARM and PowerPC.

are made towards GPT support, which should follow soon)

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.

- extend ub_dev_read() and ub_dev_recv() so that the actual len and
all error codes can be passed and processed properly; unify behaviour of
these routines
- introduce syscall general error code (API_ESYSC)
- add new diag commands: devinfo, sysinfo for U-Boot-style details about the system
configuration
- better memory info summary
- style corrections

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.

o Move the API prototypes to a separate header (glue.h)
o Allow the platform to hint libuboot about where to look
for the API signature. The uboot_address variable is
expected to be defined by the platform.
