c3bec5478f arm: omap3: Detect boot mode very early
Fixes 4bd754d8ab ("arm: omap: Detect boot mode very early") where
the intent was to store the boot params information in a known
location and pass it to SPL very early. Unfortunately it didn't
account for OMAP3 boards.

This patch adds adds this functionality back into OMAP3 boards.

409a81ddd4 am33xx: board: Refactor USB initialization into separate function
The declaration of otg*_plat and otg*_board_data is guarded by
CONFIG_USB_MUSB_*, but their use in arch_misc_init is not. The
ifdef flow goes something like:

if (CONFIG_USB_MUSB_* && other_conditions)
	declare usb_data
if (other_conditions)
	use usb_data

Thus when CONFIG_USB_MUSB_* is not declared, we try to use the
data structures, but these structures aren't defined.

To fix this, move the USB initialization code into the same #ifdef
which guards the declaration of the data structures. Since the DM_USB
vs legacy cases are completely different, use two versions of
arch_misc_init(), for readability.

ab86dc7948 ARM: ti816x: Fix enabling GPIO0, enable GPIO1 as well
The TI816x has 2 GPIO banks.  For bank 0 we had been clearing the enable

00bbe96eba arm: omap: Unify get_device_type() function
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)

8627733941 ti816x: Rework DDR initialization sequence
The ti816x/am389x SoC is the first generation in what U-Boot calls the
"am33xx" family.  In the first generation of this family the DDR
initialization sequence is quite different from all of the subsequent
generations.  Whereas with ti814x (second generation) we can easily work
the minor differenced between that and am33xx (third generation), our
attempts to do this for ti816x weren't sufficient.  Rather than add a
large amount of #ifdef logic to make this different sequence work we add
a new file, ti816x_emif4.c to handle the various required undocumented
register writes and sequence and leverage what we can from
arch/arm/mach-omap2/am33xx/ddr.c still.  As DDR2 has similar problems
today but I am unable to test it, we drop the DDR2 defines from the code
rather than imply that it works by leaving it.  We also remove a bunch
of other untested code about changing the speed the DDR runs at.

drop CONFIG_DEFAULT_OMAP_RESET_TIME_MAX_USEC entirely.  The contents of
doc/README.omap-reset-time make a good help entry, so adjust them
slightly and delete the file.  Move the comment about range to where we
use the value now, and have Kconfig enforce the upper bound.

59041a5084 arm: am33xx: Fix MPU opp selection
Update MPU frequencies and voltages as per the latest
DM[1] dated: OCT 2011 Revised APRIL 2016, Section 5.4.

 -------------------------------------------------------

There is no eFuse blown on PG1.0 Silicons due to which there is
no way to detect the maximum frequencies supported. So default
to OPP100 for which both frequency and voltages are common on both
the packages.

b8c908762c ti: clocks: Fix do_enable_clocks() to accept NULL pointers as input parameters
Up till this commit passing NULL as input parameter was allowed, but not
handled properly.

When one passed NULL to one of this function parameters, the code was
executed causing data abort.

However, what is more interesting, the abort was not caught because of code
execution in HYP mode with masked CPSR A bit ("Imprecise Data Abort mask bit).
The TI's AM57xx SoC switch to HYP mode with A bit masked in lowlevel_init.S
due to SMC call. Such operation (by default) is performed in SoC ROM code.

The problem would pop up when one:
- Switch back to SVC mode after disabling LPAE support
- Somebody enables A bit (by executing cpsie a asm instruction)

and then the previously described exception would be caught.

4d451c0082 ARM: OMAP2+: define _image_binary_end to fix SPL_OF_CONTROL
To make SPL_OF_CONTROL work on OMAP2+ SoCs, _image_binary_end must be
defined in the linker script along with CONFIG_SPL_SEPARATE_BSS.

a051a99f0d ARM: am43xx: fix SOC revision print outs
Currently, AM43xx just re-uses the version strings from AM33xx which is
wrong; the actual values for AM43xx are different. Fix this by adding
a separate version string array for AM43xx and use this instead.

d5abcf94c7 ti: boot: Register the MMC controllers in SPL in the same way as in u-boot
To keep a consistent MMC device mapping in SPL and in u-boot, let's
register the MMC controllers the same way in u-boot and in the SPL.
In terms of boot time, it doesn't hurt to register more controllers than
needed because the MMC device is initialized only prior being accessed for
the first time.
Having the same device mapping in SPL and u-boot allows us to use the
environment in SPL whatever the MMC boot device.

19a75b8cf8 arm: omap3: Bring back ARM errata workaround 725233
The workaround for ARM errata 725233 had been lost since
commit 45bf05854b (armv7: adapt omap3 to the new cache
maintenance framework). Bring it back in order to avoid
very difficult to reproduce, but actually encountered in
the wild CPU deadlocks when running software rendered
X11 desktop on OMAP3530 hardware.

7584f2e0fb arm: omap3: Compile clock.c with -marm option to unbreak OMAP3530
Boards with OMAP3530 SoC fail to boot since commit bd2c4522c2
("ti: armv7: enable EXT support in SPL (using ti_armv7_common.h)")
because it enabled the use of Thumb2 for the SPL.

Experiments have shown that the deadlock happens in the
prcm_init() function from 'arch/arm/mach-omap2/omap3/clock.c'.

This patch enforces the compilation of clock.c source file in
ARM mode and makes the deadlock disappear. We are yet to figure
out the root cause of the problem. Still this is somewhat
better than having non-bootable boards for years.
