commit 06a040a3 ("cmd: mtdparts: fix null pointer dereference in parse_mtdparts")
removed the initialization of a pointer variable, which is
subsequently used in a debug() call. This produces an uninitialized
variable warning, when compiling with DEBUG defined.

relocate_code() calculates the relocation offset wrt. the symbol
__image_copy_start which happens to have the same value as
CONFIG_TEXT_BASE on most systems.
When creating an i.MX boot image with an integrated IVT it is
convenient to have CONFIG_TEXT_BASE point to the start of the IVT
that is prepended to the actual code. Thus CONFIG_TEXT_BASE will
differ from __image_copy_start, while the calculation
'gd->relocaddr - __image_copy_start' still gives the right relocation
offset.

The cp_delay() function was introduced because of a missing 'volatile'
attribute to the 'asm' statement in get_cr() which led to the 'mrc'
instruction in get_cr() being optimised out eventually.
This has been fixed in commit 53fd4b8c ("arm: mmu: Add missing volatile for reading SCTLR register")
but the bogus cp_delay() function which was introduced as a workaround
for the malfunctioning get_cr() was never removed.

The current implementation makes it look like the 'if (from_spl)' part is
dead code because these features are not enabled for sandbox. We could

Using u-boot-2017.05 on i.MX6UL we ran into following problem:
Initially U-Boot could be started normally.
If we added one random command in configuration, the newly generated
image hung at startup (last output was DRAM:  256 MiB).

We tracked this down to a data abort within relocation (relocated_code).

relocated_code in arch/arm/lib/relocate.S copies 8 bytes per loop
iteration until the source pointer is equal to __image_copy_end.
In a good case __image_copy_end was aligned to 8 bytes, so the loop
stopped as suggested, but in an errornous case __image_copy_end was
not aligned to 8 bytes, so the loop ran out of bounds and caused a
data abort exception.

This patches solves the issue by aligning __image_copy_end to 8 byte
using the linker script related to arm.

I don't know if it's the correct way to solve this, so some review would
be very appreciated.

When we don't have CONFIG_BLK defined we don't have a forward
declaration of struct udevice, and thus get a warning about it on
blk_get_from_parent(), which we only have when CONFIG_BLK is set.  Move
the declaration of blk_get_from_parent() to be with the other CONFIG_BLK
parts.

Refactor OMAP3/4/5 code so that we have only one get_device_type()
function for all platforms.

Details:
 - Add ctrl variable for AM33xx and OMAP3 platforms (like it's done for
   OMAP4/5), so we can obtain status register in common way
 - For now ctrl structure for AM33xx/OMAP3 contains only status register
   address
 - Run hw_data_init() in order to assign ctrl to proper structure
 - Remove DEVICE_MASK and DEVICE_GP definitions as they are not used
   (DEVICE_TYPE_MASK and GP_DEVICE are used instead)
 - Guard structs in omap_common.h with #ifdefs, because otherwise
   including omap_common.h on non-omap4/5 board files breaks compilation

Buildman script was run for all OMAP boards. Result output:
    arm: (for 38/616 boards)
        all +352.5
        bss -1.4
        data +3.5
