The function's name is misleading as one might think it is used
generally to select the boot-mode when in reality it is only used by the
MMC driver to find out in what way it should try reading U-Boot Proper
from a device (either using a filesystem, a raw sector/partition, or an
eMMC boot partition).
Rename it to spl_mmc_boot_mode() to make it more obvious what this
function is about.

On Gen5, when the FPGA is loaded and there was some prior interaction
between the HPS and the FPGA via bridges (e.g. Linux was running and
using some of the IPs in the FPGA) followed by warm reset, it has been
observed that there might be outstanding unfinished transactions. This
leads to an obscure misbehavior of the bridge.
When the bridge is enabled again in U-Boot and there are outstanding
transactions, a read from within the bridge address range would return
a result of the previous read instead. Example:
=> bridge enable ; md 0xff200000 1
ff200000: 1234abcd
=> bridge enable ; md 0xff200010 1
ff200010: 5678dcba <------- this is in fact a value which is stored in
a memory at 0xff200000
=> bridge enable ; md 0xff200000 1
ff200000: 90effe09 <------- this is in fact a value which is stored in
a memory at 0xff200010
and so it continues. Issuing a write does lock the system up completely.
This patch opens the FPGA bridges in 'bridge enable' command, the tears
them down again, and then opens them again. This allows these outstanding
transactions to complete and makes this misbehavior go away.
However, it is not entirely clear whether this is the correct solution.

The socfpga gen5 SPL manually zeroed bss in board_init_f(). Now that the

bss is normally zeroed by crt0.S, but after board_init_f(), before

On SoCFPGA A10 systems, it can rarely happen that a reboot from Linux
will result in stale data in PL310 L2 cache controller. Even if the L2
cache controller is disabled via the CTRL register CTRL_EN bit, those
data can interfere with operation of devices using DMA, like e.g. the
DWMMC controller. This can in turn cause e.g. SPL to fail reading data
from SD/MMC.
The obvious solution here would be to fully reset the L2 cache controller
via the reset manager MPUMODRST L2 bit, however this causes bus hang even
if executed entirely from L1 I-cache to avoid generating any bus traffic
through the L2 cache controller.
This patch thus configures and enables the L2 cache controller very early
in the SPL boot process, clears the L2 cache and disables the L2 cache
controller again.
The reason for doing it in SPL is because we need to avoid accessing any
of the potentially stale data in the L2 cache, and we are certain any of
the stale data will be below the OCRAM address range. To further reduce
bus traffic during the L2 cache invalidation, we enable L1 I-cache and
run the invalidation code entirely out of the L1 I-cache.
