Use the 'video-mode' environment variable (for Freescale chips that have a
DIU display controller) to designate the full video configuration. Previously,
the DIU driver used the 'monitor' variable, and it was used only to determine
the output video port.
The old definition of the "monitor" environment variable only determines
which video port to use for output. This variable was set to a number (0,
1, or sometimes 2) to specify a DVI, LVDS, or Dual-LVDS port. The
resolution was hard-coded into board-specific code. The Linux command-line
arguments needed to be hard-coded to the proper video definition string.

The Freescale MPC8610 and MPC5121 DIU code had re-implement two features that already
existed in U-Boot: bitmap drawing and top-of-screen logo (CONFIG_VIDEO_LOGO).
So delete the 8610-specific code and use the built-in features instead.

Lots of code use this construct:
cmd_usage(cmdtp);
return 1;
Change cmd_usage() let it return 1 - then we can replace all these
ocurrances by
return cmd_usage(cmdtp);
This fixes a few places with incorrect return code handling, too.

The hush shell dynamically allocates (and re-allocates) memory for the
argument strings in the "char *argv[]" argument vector passed to
commands. Any code that modifies these pointers will cause serious
corruption of the malloc data structures and crash U-Boot, so make
sure the compiler can check that no such modifications are being done
by changing the code into "char * const argv[]".
This modification is the result of debugging a strange crash caused
after adding a new command, which used the following argument
processing code which has been working perfectly fine in all Unix
systems since version 6 - but not so in U-Boot:
int main (int argc, char **argv)
{
while (--argc > 0 && **++argv == '-') {
/* ====> */ while (*++*argv) {
switch (**argv) {
case 'd':
debug++;
break;
...
default:
usage ();
}
}
}
...
}
The line marked "====>" will corrupt the malloc data structures and
usually cause U-Boot to crash when the next command gets executed by
the shell. With the modification, the compiler will prevent this with
an
error: increment of read-only location '*argv'
N.B.: The code above can be trivially rewritten like this:
while (--argc > 0 && **++argv == '-') {
char *arg = *argv;
while (*++arg) {
switch (*arg) {
...

As discussed on the list, move "arch/ppc" to "arch/powerpc" to
better match the Linux directory structure.
Please note that this patch also changes the "ppc" target in
MAKEALL to "powerpc" to match this new infrastructure. But "ppc"
is kept as an alias for now, to not break compatibility with

Refactor and document the Freescale PIXIS code, used on most 85xx and 86xx
boards. This makes the code easier to read and more flexible.
Delete pixis.h, because none of the exported functions were actually being
used by any other file. Make all of the functions in pixis.c 'static'.
Remove "#include pixis.h" from every file that has it.
Remove some unnecessary #includes.
Make 'pixis_base' into a macro, so that we don't need to define it in every
function.
Add "while(1);" loops at the end of functions that reset the board, so that
execution doesn't continue while the reset is in progress.
Replace in_8/out_8 calls with clrbits_8, setbits_8, or clrsetbits_8, where
appropriate.
Replace ulong/uint with their spelled-out equivalents. Remove unnecessary
typecasts, changing the types of some variables if necessary.
Add CONFIG_SYS_PIXIS_VCFGEN0_ENABLE and CONFIG_SYS_PIXIS_VBOOT_ENABLE to make
it easier for specific boards to support variations in the PIXIS registers
sets. No current boards appears to need this feature.
Fix the definition of CONFIG_SYS_PIXIS_VBOOT_MASK for the MPC8610 HPCD.
Apparently, "pixis_reset altbank" has never worked on this board.

So far the console API uses the following naming convention:
======Extract======
typedef struct device_t;
int device_register (device_t * dev);
int devices_init (void);
int device_deregister(char *devname);
struct list_head* device_get_list(void);
device_t* device_get_by_name(char* name);
device_t* device_clone(device_t *dev);
=======
which is too generic and confusing.
Instead of using device_XX and device_t we change this
into stdio_XX and stdio_dev
This will also allow to add later a generic device mechanism in order
to have support for multiple devices and driver instances.

We will soon see several new MPC521x based boards added. This patch

Many of the help messages were not really helpful; for example, many
commands that take no arguments would not print a correct synopsis
line, but "No additional help available." which is not exactly wrong,
but not helpful either.
Commit ``Make "usage" messages more helpful.'' changed this
partially. But it also became clear that lots of "Usage" and "Help"
messages (fields "usage" and "help" in struct cmd_tbl_s respective)
were actually redundant.
This patch cleans this up - for example:
Before:
=> help dtt
dtt - Digital Thermometer and Thermostat
Usage:
dtt - Read temperature from digital thermometer and thermostat.
After:
=> help dtt
dtt - Read temperature from Digital Thermometer and Thermostat
Usage:

1280x1024 and 1024x768 @ 32 bpp are supported now.
DVI, Single-link LVDS, Double-link LVDS are all supported.
Environmental variable "monitor" is used to specify monitor port.
A new command "diufb" is introduced to reinitialize monitor
and display a BMP file in the memory. So far, 1-bit, 4-bit,
8-bit and 24-bit BMP formats are supported.
diufb init
- initialize the diu driver
Enable the port specified in the environmental variable "monitor"
diufb addr
- display bmp file in memory.
The bmp image should be no bigger than the resolution, 1280x1024
for DVI and double-link LVDS, 1024x768 for single-link LVDS.
Note, this driver allocate memory but doesn't free it after use
It is written on purpose -- to avoid a failure of reallocation
due to memory fragement.
ECC of DDR is disabled for DIU performance. L2 data cache is also disabled.
