Flush cache after the OS image is loaded into the memory.

2011-09-05T14:07:44+00:00

Since we are loading an executable image into memory we need flush it
out of the cache to possible maintain coherence on CPUs with split
instruction and data caches.  We do this for other executable image
loading command.

On PowerPC once we do this we no longer need to explicitly flush the
dcache on multi-core systems in the BOOTM_STATE_OS_PREP phase.  We now
treat the BOOTM_STATE_OS_PREP as a no-op to maintain backwards
compatibility with the bootm subcommand.

autostart: unify duplicated logic into the bootm code

2011-07-25T20:18:26+00:00

Rather than having a bunch of random commands handle autostart behavior,
unify the logic in a single place.  This also fixes building of these

different commands when bootm is disabled.

Respect memreserve regions specified in the device tree

2011-04-26T01:11:21+00:00

If a regions is reserved in the fdt, then it should not be used.  Add
the memreserve regions to the lmb so that u-boot doesn't use them to
store the initrd.

Remove device tree booting dependency on CONFIG_SYS_BOOTMAPSZ

2011-04-26T01:11:20+00:00

The previous patch makes u-boot use the full accessible size of ram as
the default boot mapped size if CONFIG_SYS_BOOTMAPSZ is not defined,
which means boot_relocate_fdt() can be changed to depend solely on
CONFIG_OF_LIBFDT.

Stop passing around bootmem_base value.

2011-04-26T01:11:19+00:00

For the calls to boot_relocate_fdt(), boot_get_cmdline(), and
boot_get_kbd(), the value of bootmem_base is always obtained by
calling getenv_bootm_low().  Since the value always comes from the
same source, the calling signature for those functions can be
simplified by making them call getenv_bootm_low() directly.

bootm: replace blob_start with image_start

2011-04-11T19:10:44+00:00

For uImage always has a 64 bytes header, we couldn't expect to do
the xip from the header but should xip from the image start.

The latter logic in that section is also move the image from image_start
to the load address, so sync this logic to the xip operation.

load_addr: move to common env code

2011-01-09T17:02:06+00:00

Rather than keep the load_addr definition with the bootm code (which
just happens to use this), move it to the common env code.  This way
we can disable bootm support completely while retaining load_addr
usage with many other commands.

do_reset: unify duplicate prototypes

2010-11-28T20:47:24+00:00

The duplication of the do_reset prototype has gotten out of hand,
and they're not all in sync.  Unify them all in command.h.

Replace CONFIG_RELOC_FIXUP_WORKS by CONFIG_NEEDS_MANUAL_RELOC

2010-10-29T19:32:07+00:00

By now, the majority of architectures have working relocation
support, so the few remaining architectures have become exceptions.
To make this more obvious, we make working relocation now the default
case, and flag the remaining cases with CONFIG_NEEDS_MANUAL_RELOC.

boot: change some arch ifdefs to feature ifdefs

2010-10-18T20:53:32+00:00

The routines boot_ramdisk_high, boot_get_cmdline and boot_get_kbd
are currently enabled by various combinations of CONFIG_M68K,
CONFIG_POWERPC and CONFIG_SPARC.

Use CONFIG_SYS_BOOT_ defines instead.

CONFIG_SYS_BOOT_RAMDISK_HIGH
CONFIG_SYS_BOOT_GET_CMDLINE
CONFIG_SYS_BOOT_GET_KBD

Define these as appropriate in arch/include/asm/config.h files.
