821c89d38c Revert "omap3: Use raw SPL by default for mmc1"
Unfortunately with this change we now are unable to do FS mode boots
from MMC1 as with the way the code works today we will always load and
assume that the hard-coded raw location contains U-Boot.  Further, we
cannot fix this by just changing other logic to try FS-then-RAW as it
would also make us have to ignore what order the ROM is telling us to
try.

This reverts commit 22d90d560a.

22d90d560a omap3: Use raw SPL by default for mmc1
Now that we fall back to the FS code path when we don't find u-boot
at the raw sector offset, there is no good reason to not default to
raw boot.

With this patch, I can successfully boot u-boot from a raw sector
offset on beagle-xm.

312db9f75f armv7: omap-common: Rework SPL board_mmc_init()
Since the changes in a1e56cf the way that we had board_mmc_init()
structured for OMAP parts (so that we always report device 0) are no
longer functional.  For now, make the case of booting from the second
device initialize both devices (we have no devices that only have the
second device as MMC).  A further rework and consolidation of the
functions should be done at a later date.

Tested on Beaglebone Black (SD and eMMC boot).

8ceb34a1d1 omap-common: SYS_BOOT fallback logic correction and support for more devices
The SYS_BOOT-based fallback shouldn't only check for one of the conditions of
use and then let the switch/case handle each boot device without enforcing the
conditions for each type of boot device again.

For instance, this behaviour would trigger the fallback for UART when
BOOT_DEVICE_UART is defined, CONFIG_SPL_YMODEM_SUPPORT is enabled (which should
be a show-stopper) and e.g. BOOT_DEVICE_USB is enabled and not
CONFIG_SPL_USB_SUPPORT.
Separating the logic for USB and UART solves this.

In addition, this adds support for more peripheral devices (USBETH and CPGMAC)
to the fallback mechanism. Note that the USBETH boot device should always be
different from the USB boot device (each should match a different bootrom
handoff case).

ed19bdaea3 omap-common: SYS_BOOT-based fallback boot device selection for peripheral boot
OMAP devices might boot from peripheral devices, such as UART or USB.
When that happens, the U-Boot SPL tries to boot the next stage (complete U-Boot)
from that peripheral device, but in most cases, this is not a valid boot device.

This introduces a fallback option that reads the SYS_BOOT pins, that are used by
the bootrom to determine which device to boot from. It is intended for the
SYS_BOOT value to be interpreted in the memory-preferred scheme, so that the
U-Boot SPL can load the next stage from a valid location.

Practically, this options allows loading the U-Boot SPL through USB and have it
load the next stage according to the memory device selected by SYS_BOOT instead
of stalling.

60c7c30aa0 omap-common: Common boot code OMAP3 support and cleanup
This introduces OMAP3 support for the common omap boot code, as well as a
major cleanup of the common omap boot code.

First, the omap_boot_parameters structure becomes platform-specific, since its
definition differs a bit across omap platforms. The offsets are removed as well
since it is U-Boot's coding style to use structures for mapping such kind of
data (in the sense that it is similar to registers). It is correct to assume
that romcode structure encoding is the same as U-Boot, given the description
of these structures in the TRMs.

The original address provided by the bootrom is passed to the U-Boot binary
instead of a duplicate of the structure stored in global data. This allows to
have only the relevant (boot device and mode) information stored in global data.
It is also expected that the address where the bootrom stores that information
is not overridden by the U-Boot SPL or U-Boot.

The save_omap_boot_params is expected to handle all special cases where the data
provided by the bootrom cannot be used as-is, so that spl_boot_device and
spl_boot_mode only return the data from global data.

All of this is only relevant when the U-Boot SPL is used. In cases it is not,
save_boot_params should fallback to its weak (or board-specific) definition.
save_omap_boot_params should not be called in that context either.

ecd8557937 fastboot: ARM: OMAP5: Enable reboot-bootloader
Implemented fb_set_reboot_flag() for OMAP5 to set
an environment variable 'dofastboot' when reboot-bootloader called.

This environment variable will be checked in boot command and fastboot
will be called if the variable is set.
If the bootcmd env variable of OMAP5 common is overwritten with board-specific
command, then these changes will not apply.

This was originally intended for DRA7 platform, but now applies to all OMAP5.

a6b541b090 TI ARMv7: Don't use GD before crt0.S has set it
Prior to this change we set the gd pointer early so that we can store
data in it.  This becomes problematic for DM changes as well as being
odd in general.  Re-work the code paths so that we don't need to set the
gd pointer so early and instead can rely upon the normal setting of it.

In order to do this we do need to move certain calls from s_init into
spl_board_init(), mainly preloader_console_init and
save_omap_boot_params.

It happens because U-Boot does not reset SATA controller before boot.
