ARM: SPL: Use CONFIG_SPL_DM not CONFIG_DM

2015-08-13T00:48:07+00:00

We now have the CONFIG_SPL_DM for code within SPL to toggle caring about
DM or not.  Without this change platforms that do enable CONFIG_DM but
not CONFIG_SPL_DM may be broken (such as OMAP5).

arm: spl: Avoid setting up a duplicate global data structure

2015-03-04T19:55:04+00:00

This is already set up in crt0.S. We don't need a new structure and don't
really want one in the 'data' section of the image, since it will be empty
and crt0.S's changes will be ignored.

As an interim measure, remove it only if CONFIG_DM is not defined. This
allows us to press ahead with driver model in SPL and allow the stragglers
to catch up.

arm: Add warnings about using gdata

2015-01-16T19:52:52+00:00

We need to get rid of this SPL-specific setting of the global_data pointer.
It is already set up in start.S immediately before board_init_f() is called,
and there may be information there that is needed (e.g. pre-reloc malloc
info).

Revert "ARM: SPL: do not set gd again"

2014-09-16T16:24:00+00:00

At the high level, the problem is that we set gd multiple times (and
still do, even after the commit we're reverting).  We set important
parts of gd to the copy which is not above stack but rather in the data
section.  For the release, we're going to revert this change and for the
next release we shall correct things to only, really, set gd once to an
appropriate location and ensure that comments about it are correct too.

This reverts commit f0c3a6c4ad09210d5d4aeafe87685ee75e5683d6.

ARM: SPL: do not set gd again

2014-09-09T11:50:57+00:00

Just before calling board_init_f, crt0.S has already
reserved space for the initial gd on the stack. There
should be no need to allocate it again.

arm: spl: Do not set the stack pointer twice

2013-09-14T09:14:21+00:00

Because the stack pointer is already set in arch/arm/lib/crt0.S,
we do not need to set it in arch/arm/lib/spl.c.

arm: spl: For Falcon Mode, set a default machid of ~0

2013-08-15T22:38:35+00:00

With device trees, boards do not always set CONFIG_MACH_TYPE now, so we
must not rely on this define being set.  The kernel uses ~0 to see if we
have a valid machine number or not, so set that as the default, invalid
machine, id and only fix if CONFIG_MACH_TYPE is set.

Replace __bss_end with bss_end

2013-03-15T20:13:54+00:00

Note this is a tree-wide change affecting multiple architectures.

At present we use __bss_start, but mostly __bss_end__. This seems
inconsistent and in a number of places __bss_end is used instead.

Change to use __bss_end for the BSS end symbol throughout U-Boot. This
makes it possible to use the asm-generic/sections.h file on all
archs.

SPL: Create arch/arm/lib/spl.c for board_init_f and jump_to_image_linux

2012-09-27T16:49:59+00:00

In SPL (CONFIG_SPL_FRAMEWORK) board_init_f must setup the stack pointer,
clear the BSS and call board_init_r.  We mark this as weak as some
platforms may need to perform additional initalization at this point.
We provide a gd that we know will be in a usable location, once the BSS
has been cleared to help with this as well.  Finally, we no longer call
relocate_code so remove that from the armv7 version.

Next, both board_init_f and jump_to_image_linux are going to be
inherently arch-specific, so move these versions to arch/arm/lib/spl.c
