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: refactor image detection and os load steps

2008-08-26T21:41:43+00:00

Created a bootm_start() that handles the parsing and detection of all
the images that will be used by the bootm command (OS, ramdisk, fdt).
As part of this we now tract all the relevant image offsets in the
bootm_headers_t struct. This will allow us to have all the needed
state for future sub-commands and lets us reduce a bit of arch
specific code on SPARC.

Created a bootm_load_os() that deals with decompression and loading
the OS image.

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.
