Print kernel args as late as possible before jumping into kernel.

Clarify an error message. The addresses here are
really offsets within the primary mapped memory block
(which may not start at address zero).

Do metadata relocation fixup on all loaded modules, not just the kernel.

- Implement "fdt mres" sub-command that prints reserved memory regions
- Add "fdt addr" subcommand that lets you specify preloaded blob address
- Do not pre-initialize blob for "fdt addr"
- Do not try to load dtb every time fdt subcommand is issued,
do it only once
- Change the way DTB is passed to kernel. With introduction of "fdt addr"
actual blob address can be not virtual but physical or reside in
area higher then 64Mb. ubldr should create copy of it in kernel area
and pass pointer to this newly allocated buffer which is guaranteed to work
in kernel after switching on MMU.
- Convert memreserv FDT info to "memreserv" property of root node
FDT uses /memreserve/ data to notify OS about reserved memory areas.
Technically it's not real property, it's just data blob, sequence
of <start, size> pairs where both start and size are 64-bit integers.
It doesn't fit nicely with OF API we use in kernel, so in order to unify
thing ubldr converts this data to "memreserve" property using the same
format for addresses and sizes as /memory node.

Print kernel args when booting the kernel.

Add the flags parameter to the disk_open() function and DISK_F_NOCACHE
flag, that disables the caching of partition tables metadata.
Use this flag for floppies in the libi386/biosdisk driver.

Almost each time when loader opens a file, this leads to calling
disk_open(). Very often this is called several times for one file.
This leads to reading partition table metadata for each call. To
reduce the number of disk I/O we have a simple block cache, but it
is very dumb and more than half of I/O operations related to reading
metadata, misses this cache.

Introduce new cache layer to resolve this problem. It is independent
and doesn't need initialization like bcache, and will work by default
for all loaders which use the new DISK API. A successful disk_open()
call to each new disk or partition produces new entry in the cache.
Even more, when disk was already open, now opening of any nested
partitions does not require reading top level partition table.
So, if without this cache, partition table metadata was read around
20-50 times during boot, now it reads only once. This affects the booting
from GPT and MBR from the UFS.

Update according to the change of struct uboot_devdesc.

Build disk.c only when DISK_SUPPORT is enabled.

Update uboot's disk driver to use new DISK API.

Use disk_fmtdev() and disk_parsedev() functions from the new DISK API.

Make struct uboot_devdesc compatible with struct disk_devdesc.

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.

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).

Ooops. Back out changes to main.c from r235094.

This change is specific to BeagleBone; I need to figure out how to
generalize this before committing.

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.

- 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.

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
