gpmc timeout is disabled and the reset counter
is set to 0. However, if later a driver activates
the timeout setting the reset to a valid value,
the old reset value with zero is still valid
for the first access. In fact, the timeout block
loads the reset counter after a successful access.
Found on a am335x board with a FPGA connected
to the GPMC bus together with the NAND.
When the FPGA driver in kernel activates
the timeout, the system hangs at the first access
by the NAND driver.

configuration should be reset but not enabled. Enabling causes the

The calling code seems a bit in doubt about the return
value of fdtdec_lookup_phandle. Since it returns a negative
value on error (and fdt_node_offset_by_phandle as well),
check for that.

Currently cntvoff_el2 is initialised with an arbitrary bag of bits
derived from the initial value of cnthctl_el2 on the current CPU. This is
somewhat odd and problematic as some of these bits are UNKNOWN at reset
and may differ across CPUs (which may cause an OS at EL1 to observe time
going backwards across CPUs).
This patch instead initialises cntvoff_el2 with xzr, giving the register
a consistent value of zero on all CPUs.

After enabling a module, SW has to wait on IDLEST bit
until it is Fully functional. This wait is missing for UART module
and there is a immediate access of UART registers after this. So there
is a chance of hang on this module( This can happen when we are running
from MPU SRAM). So waiting for IDLEST bit.

With the changes to the i2c framework (and adopting the omap24xx_i2c
driver to them) we can no longer call i2c functions prior to gd having
been set and cleared. When SPL booting, this is handled by setting gd
to point to SRAM in s_init. However in the cases where we are loaded
directly by ROM (memory mapped NOR or QSPI) we need to make use of the
normal hooks to slightly delay these calls.

We have two contexts for booting these platforms. One is SPL which is
roughly: reset, cpu_init_crit, lowlevel_init, s_init, sdram_init, _main,
board_init_f from SPL, ... then U-Boot loads. The other is a
memory-mapped XIP case (NOR or QSPI) where we do not run an SPL. In
this case we go, roughly: reset, cpu_init_crit, lowlevel_init, s_init,
_main, regular board_init_f.
In the first case s_init will set a valid gd and then be able to call
sdram_init which in many cases will need i2c (which needs a valid gd for
gd->cur_i2c_bus). In this second case we must (and are able to and
should) defer sdram_init() into dram_init() called by board_init_f as gd
will have been set in _main and cleared in board_init_f.

The ePOS EVM and EVM SK have QSPI as an option to boot. Add a qspiboot
target that utilizes QSPI for env and so forth as an example of best
practices. As QSPI is booted from directly we need to chang
CONFIG_SYS_TEXT_BASE.
Note that on ePOS EVM the QSPI and NAND are mutually exclusive choices
we need to handle that elsewhere, once NAND support is also added.

arch/arm/include/asm/spl.h requires all SoCs to have
arch/arm/include/asm/arch-*/spl.h.
But many of them just define BOOT_DEVICE_* macros.
Those macros are used in the "switch (boot_device) { ... }"
statement in common/spl/spl.c.
So they should not be archtecture specific, but be described as
a simpile enumeration.
This commit merges most of arch/arm/include/asm/arch-*/spl.h
into arch/arm/include/asm/spl.h.
With a little more effort, arch-zynq/spl.h and arch-socfpga/spl.h
will be merged, while I am not sure about OMAP and Exynos.
