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.

fdt: Overwrite /chosen node in bootm if it already exists in the dtb

2008-10-02T02:01:52+00:00

Set force parameter in fdt_chosen() call in do_bootm_linux() call.
Without this, the chosen node is not overwritten if it already
exists.

powerpc: Fix bootm to boot up again with a Ramdisk

2008-09-13T00:03:38+00:00

Commit 2a1a2cb6 didnt remove the dummy mem reservation in fdt_chosen,
and this stopped Linux from booting with a Ramdisk. This patch fixes
this, by deleting the useless dummy mem reservation.

When booting with a Ramdisk, a fix offset FDT_RAMDISK_OVERHEAD is now
added to of_size, so we dont need anymore a dummy mem reservation.

I measured the value of FDT_RAMDISK_OVERHEAD on a MPC8270 based
system (=0x44 bytes) and rounded it up to 0x80).

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.

fdt: refactor initrd related code

2008-08-26T21:45:20+00:00

Created a new fdt_initrd() to deal with setting the initrd properties
in the device tree and fixing up the mem reserve.  We can use this
both in the choosen node handling and lets us remove some duplicated
code when we fixup the initrd info in bootm on PPC.
