      image: Implement IH_TYPE_KERNEL_NOLOAD · b9b50e89
      由 Stephen Warren 提交于 
      The legacy uImage format includes an absolute load and entry-point
address. When bootm operates on a kernel uImage in memory that isn't
loaded at the address in the image's load address, U-Boot will copy
the image to its address in the header.

Some kernel images can actually be loaded and used at any arbitrary
address. An example is an ARM Linux kernel zImage file. To represent
this capability, IH_TYPE_KERNEL_NOLOAD is implemented, which operates
just like IH_TYPE_KERNEL, except that the load address header is
ignored, and U-Boot does not copy the image to its load address, but
rather uses it in-place.

This is useful when sharing a single (uImage-wrapped) zImage across
multiple boards with different memory layouts; in this case, a specific
load address need not be picked when creating the uImage, but instead
is selected by the board-specific U-Boot environment used to load and
boot that image.

v2: Rename from IH_TYPE_KERNEL_ANYLOAD to IH_TYPE_KERNEL_NOLOAD.

      mkimage: adding support for Davinci AIS image · 4962e38e
      由 Stefano Babic 提交于 
      Some Davinci processors supports the Application
Image Script (AIS) boot process. The patch adds the generation
of the AIS image inside the mkimage tool to make possible
to generate a bootable U-boot without external tools
(TI Davinci AIS Generator).

      checkpatch whitespace cleanups · 712fbcf3
      由 Stephen Warren 提交于 
      This avoids the following checkpatch warning in later patches:

ERROR: "(foo*)" should be "(foo *)"
ERROR: space required before the open brace '{'
ERROR: space prohibited before that close parenthesis ')'
ERROR: spaces required around that '||' (ctx:WxV)
WARNING: space prohibited between function name and open parenthesis '('
WARNING: line over 80 characters

This fixes all the white-space warnings/errors in my subsequent patch,
and within this current patch. A number of other checkpatch warnings
and errors are still present in this patch itself, but are beyond simple
whitespace fixes, so are not solved by this patch.

      Make sure that argv[] argument pointers are not modified. · 54841ab5
      由 Wolfgang Denk 提交于 
      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) {
			...

      add lzop decompression support · 20dde48b
      由 Peter Korsgaard 提交于 
      Add lzop decompression support to the existing lzo bitstream handling
(think gzip versus zlib), and support it for uImage decompression if
CONFIG_LZO is enabled.

Lzop doesn't compress as good as gzip (~10% worse), but decompression
is very fast (~0.7s faster here on a slow ppc). The lzop decompression
code is based on Albin Tonnerre's recent ARM Linux lzo support patch.

      compiler.h: unify system ifdef cruft here · 37566090
      由 Mike Frysinger 提交于 
      Shove a lot of the HOSTCC and related #ifdef checking crap into the new
compiler.h header so that we can keep all other headers nice and clean.

Also introduce custom uswap functions so we don't have to rely on the non
standard implementations that a host may (or may not in the case of OS X)
provide.  This allows mkimage to finally build cleanly on an OS X system.

      Add support for building native win32 tools · 2f8d396b
      由 Peter Tyser 提交于 
      Add support for compiling the host tools in the tools directory using
the MinGW toolchain.  This produces executables which can be used on
standard Windows computers without requiring cygwin.

One must specify the MinGW compiler and strip utilities as if they
were the host toolchain in order to build win32 executables, eg:

make HOSTCC=i586-mingw32msvc-gcc HOSTSTRIP=i586-mingw32msvc-strip tools

      bootm: Add subcommands · 49c3a861
      由 Kumar Gala 提交于 
      Add the ability to break the steps of the bootm command into several
subcommands: start, loados, ramdisk, fdt, bdt, cmdline, prep, go.

This allows us to do things like manipulate device trees before
they are passed to a booting kernel or setup memory for a secondary
core in multicore situations.

Not all OS types support all subcommands (currently only start, loados,
ramdisk, fdt, and go are supported).
