bootm: Add subcommands

2008-10-28T23:59:50+00:00

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).

Added arch_lmb_reserve to allow arch specific memory regions protection

2008-10-18T19:54:04+00:00

Each architecture has different ways of determine what regions of memory
might not be valid to get overwritten when we boot.  This provides a
hook to allow them to reserve any regions they care about.  Currently
only ppc, m68k and sparc need/use this.

bootm: refactor do_reset and os boot function args

2008-08-26T21:48:01+00:00

There is no need for each OS specific function to call do_reset() we
can just do it once in bootm. This means its feasible on an error for
the OS boot function to return.

Also, remove passing in cmd_tbl_t as its not needed by the OS boot
functions.  flag isn't currently used but might be in the future so
we left it alone.

bootm: move lmb into the bootm_headers_t structure

2008-08-26T21:38:48+00:00

To allow for persistent state between future bootm subcommands we
need the lmb to exist in a global state.
Moving it into the bootm_headers_t allows us to do that.

bootm: refactor ramdisk locating code

2008-08-26T21:35:24+00:00

Move determing if we have a ramdisk and where its located into the
common code. Keep track of the ramdisk start and end in the
bootm_headers_t image struct.

bootm: refactor entry point code

2008-08-26T21:31:33+00:00

Move entry point code out of each arch and into common code.
Keep the entry point in the bootm_headers_t images struct.

Fix fallout from autostart revert

2008-08-11T22:06:34+00:00

The autostart revert caused a bit of duplicated code as well as
code that was using images->autostart that needs to get removed so
we can build again.

Restore the ability to continue booting after legacy image overwrite

2008-04-18T06:59:05+00:00

Before new uImage code was merged, bootm code allowed for the kernel image to
get overwritten during decompresion. new uImage introduced a check for image
overwrites and refused to boot the image that got overwritten. This patch
restores the old behavior. It also adds a warning when the image overwriten is
a multi-image file, because in such case accessing componentes other than the
first one will fail.

[new uImage] Add new uImage format support to arch specific do_bootm_linux() routines

2008-03-12T09:33:00+00:00

This patch updates architecture specific implementations of
do_bootm_linux() adding new uImage format handling for
operations like get kernel entry point address, get kernel
image data start address.
