When the base registers are read from device tree the base is not
0x48030100 as the driver expects, but 0x48030000, resulting in
non functioning SPI. To deal with this, use same idea as how this
is done in the linux kernel (drivers/spi/spi-omap2-mcspi.c) and
add a structure with a field that is used to shift the registers
on these systems.

This function returns an error code and its caller may be able to fix the
error. For example fit_handle_file() expands the device tree to fit if there
is a lack of space.
In this case the caller does not want an error displayed. It is confusing,
since it suggests that something is wrong, when it fact everything is fine.

Commit 4f144a416469 "malloc: work around some memalign fragmentation
issues" enhanced memalign() so that it can succeed in more cases where
heap fragmentation is present. However, it did not solve as many cases
as it could. This patch enhances the code to cover more cases.
The alignment code works by allocating more space than the user requests,
then adjusting the returned pointer to achieve alignment. In general, one
must allocate "alignment" bytes more than the user requested in order to
guarantee that alignment is possible. This is what the original code does.
The previous enhancement attempted a second allocation if the padded
allocation failed, and succeeded if that allocation just happened to be
aligned; a fluke that happened often in practice. There are still cases
where this could fail, yet where it is still possible to honor the user's
allocation request. In particular, if the heap contains a free region that
is large enough for the user's request, and for leading padding to ensure
alignment, but has no or little space for any trailing padding. In this
case, we can make a third(!) allocation attempt after calculating exactly
the size of the leading padding required to achieve alignment, which is
the minimal over-allocation needed for the overall memalign() operation to
succeed if the third and second allocations end up at the same location.
This patch isn't checkpatch-clean, since it conforms to the existing
coding style in dlmalloc.c, which is different to the rest of U-Boot.

boots to shell. This was seen on my board, but not on Jian's board.
Debugging shows that the TSC timer calibration against PIT fails

time TSC/PIT may not be stable enough for the calibration to pass.

Per ACPI spec, during ACPI OS initialization, OSPM can determine
that the ACPI hardware registers are owned by SMI (by way of the
SCI_EN bit in the PM1_CNT register), in which case the ACPI OS
issues the ACPI_ENABLE command to the SMI_CMD port. The SCI_EN bit
effectively tracks the ownership of the ACPI hardware registers.
However since U-Boot does not support SMI, we report all 3 fields
in FADT (SMI_CMD, ACPI_ENABLE, ACPI_DISABLE) as zero, by following
the spec who says: these fields are reserved and must be zero on
system that does not support System Management mode.
U-Boot seems to behave in a correct way that the ACPI spec allows,
at least Linux does not complain, but apparently Windows does not
think so. During Windows bring up debugging, it is observed that
even these 3 fields are zero, Windows are still trying to issue SMI
with hardcoded SMI port address and commands, and expecting SCI_EN
to be changed by the firmware. Eventually Windows gives us a BSOD
(Blue Screen of Death) saying ACPI_BIOS_ERROR and refuses to start.
To fix this, turn on the SCI_EN bit by ourselves. With this patch,
now U-Boot can install and boot Windows 8.1/10 successfully with
the help of SeaBIOS using legacy interface (non-UEFI mode).

PIRQ routing table checksum is fixed up in copy_pirq_routing_table(),
which is fine if we only write the configuration table once. But with
the SeaBIOS case, when we write the table for the second time, the
checksum will be fixed up to zero per the checksum algorithm, which
is caused by the checksum field not being zero before fix up, since
the checksum has already been calculated in the first run.
To fix this, move the checksum fixup to create_pirq_routing_table(),
so that copy_pirq_routing_table() only does what its function name
suggests: copy the table to somewhere else.
