077e1958ca x86: Add RAM bootstrap functionality
Add a parameter to the 32-bit entry to indicate if entry is from Real
Mode or not. If entry is from Real Mode, execute the destructive 'sizer'
routine to determine memory size as we are booting cold and running in
Flash. If not entering from Real Mode, we are executing a U-Boot image
from RAM and therefore the memory size is already known (and running
'sizer' will destroy the running image)

There are now two 32-bit entry points. The first is the 'in RAM' entry
point which exists at the start of the U-Boot binary image. As such,
you can load u-boot.bin in RAM and jump directly to the load address
without needing to calculate any offsets. The second entry point is
used by the real-to-protected mode switch

This patch also changes TEXT_BASE to 0x6000000 (in RAM). You can load
the resulting image at 0x6000000 and simple go 0x6000000 from the u-boot
prompt

Hopefully a later patch will completely elliminate any dependency on
TEXT_BASE like a relocatable linux kernel (perfect world)

This patch allows the low-level assembler boot-strap to obtain the RAM
size without calling the destructive 'sizer' routine. This allows

8cd852824d cmd_onenand.c: moved to standard subcommand handling
On the fly also fixed the following things:
- write help talked about a parameter oob, but that one was not used, so
  removed it from the help message.
- the test command also allowed a force subcommand but didn't use it.
  eliminated the code.
- do_onenand made static
- do_onenand contained
	int blocksize;
	...
	mtd = &onenand_mtd;
	this = mtd->priv;
	blocksize = (1 << this->erase_shift);
  As blocksize was not used the last two statements were unneeded so
  removed them.
  The first statement (mtd = ....) assigns to a global. Not sure if it
  is needed, and since I could not test this, left the line for now

3882d7a5a5 ppc: unused memory region too close to current stack pointer
This avoids a possible overwrite of the (end of) ramdisk by u-boot.
The unused memory region for ppc boot currently starts 1k below the
do_bootm->bootm_start->arch_lmb_reserve stack ptr. This isn't enough since
do_bootm->do_bootm_linux->boot_relocate_fdt calls printf which may
very well use more than 1k stack space.

52dbac69c2 fix print_size printing fractional gigabyte numbers on 32-bit platforms
In print_size(), the math that calculates the fractional remainder of a number
used the same integer size as a physical address.  However, the "10 *" factor
of the algorithm means that a large number (e.g. 1.5GB) can overflow the
integer if we're running on a 32-bit system.  Therefore, we need to
disassociate this function from the size of a physical address.

bd75db3feb smc911x driver frame alignment patch
SMSC911x chips have alignment function to allow frame payload data
(which comes after 14-bytes ethernet header) to be aligned at some
boundary when reading it from fifo (usually - 4 bytes boundary).
This is done by inserting fake zeros bytes BEFORE actual frame data when
reading from SMSC's fifo.
This function controlled by RX_CFG register. There are bits that
represents amount of fake bytes to be inserted.

Linux uses alignment of 4 bytes. Ethernet frame header is 14 bytes long,
so we need to add 2 fake bytes to get payload data aligned at 4-bytes
boundary.
Linux driver does this by adding IP_ALIGNMENT constant (defined at
skb.h) when calculating fifo data length. All network subsystem of Linux
uses this constant too when calculating different offsets.

But u-boot does not use any packet data alignment, so we don't need to
add anything when calculating fifo data length.
Moreover, driver zeros the RX_CFG register just one line up, so chip
does not insert any fake data at the beginig. So calculated data length
is always bigger by 1 word.

It seems that at almost every packet read we get an underflow condition
at fifo and possible corruption of data. Especially at continuous
transfers, such as tftp.

Just after removing this magic addition, I've got tftp transfer speed as
it aught to be at 100Mbps. It was really slow before.

It seems that fifo underflow occurs only when using byte packing on
32-bit blackfin bus (may be because of very small delay between reads).

9739946cc5 ./net/net.c - make Microsoft dns servers happy with random_port() numbers
For some reason, (which I can't find any documentation on), if U-Boot
gives a port number higher than 17500 to a Microsoft DNS server, the
server will reply to port 17500, and U-Boot will ignore things (since
that isn't the port it asked the DNS server to reply to).

This fixes that by ensuring the random port number is less than 17500.
