At this point U-Boot will build and run on x86 under Linux.
The idea is to define a new architecture called 'sandbox', alongside ARM
and x86. This runs natively on Linux to suit the host machine. All
hardware access is either omitted or emulated.
The purpose of this system is to test the bulk of the non-hardware-specific
U-Boot code. We can mock the SPI flash, GPIOs, UART and keyboard, then test
that U-Boot behaves as we wish.

The dependency rules are currently done in a shell 'for' loop. This does not
permit Makefile variables to adjust preprocessor flags as is done with normal
compile flags, using the CFLAGS_path/file.o syntax.
This change moves the dependency generation into the Makefile itself, and
permits a CPPFLAGS_path/file.o to adjust preprocessor flags on a file or
directory basis.
The CPPFLAGS_... variable is also folded into CFLAGS during the build.

This uart simply writes to stdout and reads from stdin. We might imagine
instead buffering the data so that a test interface can check output and
inject input.

By default sections are 16-byte aligned on some architectures, but the
command name structure (struct cmd_tbl_s) does not have padding to
16 bytes. This reduces the alignment to 4-bytes so that the command
table can be accessed correctly on any architecture.
(Note: this needs doing properly)

Add pxe command, which is intended to mimic PXELINUX functionality.
'pxe get' uses tftp to retrieve a file based on UUID, MAC address or IP

Existing ctype checks are implemented using a 256 byte lookup table,
allowing each character to be in any of 8 character classes. Since there
are 8 existing character classes without the blank class, I implemented
isblank without using the lookup table. Since there are only two blank
characters - tab and space - this is a more reasonable approach than
doubling the size of the lookup table to accommodate one more class.

commit a45dde2293 changed the dm9000
direct register access to standard IO. This should work
on the ColdFire platform as there are corresponding macros for
the LE devices. But the hardware settings on some ColdFire boards had
swapped the byte order which make the original macros such as out_le16
cannot work. To avoid changing the common io access code on ColdFire
platform, the DM9000_BYTE_SWAPPED define was added to make the dm9000 use
__raw* IO access on some ColdFire boards.

mx3fb.c was based on CONFIG_LCD and is moved by this patch to
CONFIG_VIDEO, which has greater freedom in selecting videomodes
even at runtime.
This renders the accumulating list of display defines
(CONFIG_DISPLAY_VBEST..., CONFIG_DISPLAY_C057...) obsolete as
these may be setup through env variables:
uboot> setenv mydisplay 'video=ctfb❌240,y:320,depth:16,mode:0,pclk:185925,
le:9,ri:17,up:7,lo:10,hs:1,vs:1,sync:100663296,vmode:0'
uboot> setenv videomode ${mydisplay}
This commit also fixes the board config files for qong and
imx31_phycore boards as needed. The videomode settings of
previously supported displays are added to CONFIG_EXTRA_ENV_SETTINGS
now. CONFIG_SYS_MALLOC_LEN for imx31_phycore board is increased
to make the frame buffer allocation working with the changed
driver.

The framebuffer driver for MX5 is based on CONFIG_LCD.
In the current implementation, there is a serious bug
because the required memory is allocated before
relocation, but the driver knows only later which is
the resolution of the display. The patch switches the driver
to CONFIG_VIDEO and the memory is allocated by the driver itself.
We also need to switch the vision2 board code and config file
in the same commit so that this commit will be bisectable.

If compressed data is located in sectors at the end of the flash and
it's offset + input stream size > 0xFFFFFFFF, the uncompressing time
is very long, since processing of the stream is done bytewise (and
not blockwise) due to overflow in inflate_fast() while calculation
and checking for enough input available.
Check for this overflow condition and limit the available stream
input size to the actually max. possible input size. This fixes
the problem.
The issue is easily reproduceable by placing a gziped bitmap in flash,
e.g. at FFF80000, and running 'bmp' commands like 'bmp info FFF80000'
or 'bmp display FFF80000'. The uncompressing can take up to 3 sec.
whereas it should normaly take a fraction of a second. If the
'splashimage' environment variable points to this address, the
booting time also increases significantly.

PCI cards might need some time after reset to respond. On some
boards (mpc5200 or mpc8260 based) the PCI bus reset is deasserted
at pci_init_board() time, so we currently can not use available
"pcidelay" option for waiting before PCI bus scan since this
waiting takes place before calling pci_init_board(). By moving
the pcidelay code to the new location using of the "pcidelay"
option is possible on mpc5200 or mpc8260 based boards, too.
Since pci_hose_scan() could be called multiple times, restrict
the function to wait only during its first call and to ignore
pcidelay for any further call (as pointed out by Matthias).
