The 4KB padding doesn't seem necessary since we don't normally adjust the

For secure boot systems it is common to have a read-only U-Boot which starts
the machine and jumps to a read-write U-Boot for actual booting the OS. This
allows the read-write U-Boot to be upgraded without risk of permanently
bricking the machine. In the event that the read-write U-Boot is corrupted,
the read-only U-Boot can detect this with a checksum and boot into a
recovery flow.

To support this, add a way to detect when U-Boot is run from SPL as opposed
to some other method, such as booted directly (no SPL) or started from
another source (e.g. a primary U-Boot). This works by putting a special value
in r0.

For now we rely on board-specific code to actually check the register and
set a flag. At some point this could be generalised, perhaps by using a spare
register and passing a flag to _main and/or board_init_f().

This commit does not implement any feature, but merely provides the API for
boards to implement.

Due to absence of CONFIG_SYS_64BIT_LBA, u-boot-sunxi currently has
no support for the (GPT) partioning scheme of large disks > 2TB.
While the AHCI driver seems to handle this nicely, the problem is
that lbaint_t values get truncated to 32-bit.

This patch sets CONFIG_SYS_64BIT_LBA from sunxi_common.h for all
SoCs that support AHCI (CONFIG_SUNXI_AHCI).

Enable the EC and keyboard, using the SPI bus.

The EC driver requires a particular format and a deactivation delay. Also
U-Boot does not support interrupts.

For now, adjust the device tree to comply. At some point we should tidy
this up to support interrupts and make tegra and exynos use the same setup.

At present the driver does not properly honour the requested SPI CS
deactivation delay since the SPI bus is changed in the claim_bus() method.

Everything the claim_bus() method does can be done when the device is probed
(setting the speed and mode) and at the start of a new transfer (where the
fifo_status is already cleared). So drop this method.

Also, until the delay is complete, we should not touch the bus, so make sure
that spi_cs_activate() is called before other things are done in the xfer()
method.
