For Exynos/snow, cpu_info and power modules and also some parts of
the GPIO API (which require timer and pwm modules) are not used in the
current bootblock. Clock init only needs to be used if early console
is enabled.
Now our bootblock is 22420 bytes with early serial console and 11192
bytes without. Those include the 8KB BL1 region.

This moves GPIO setup from chip-specific SPI code to mainboard-
specific bootblock code. This makes exynos_spi_open a bit more
generic so it can eventually be used for any SPI channel. This
also benefits CBFS since the user can set media->context to
to any set of SPI registers.

The common part of the bootblock resets the nvram data if it's found
to be invalid. Since that code is compiled with romcc in i386 mode,
there's a shortage on registers.
Try to reduce the strain by doing things smarter: cmos_write_inner
is the same as cmos_write, just that it doesn't check if the RTC is
disabled. Since we just disabled it before, we can assume that it is so.

For arm/snow, current bootblock is larger than previously assigned CBFS offset
and will fail to boot. To prevent this happening again in future, cbfstool now
checks if CBFS will overlap bootblock.
A sample error message:
E: Bootblock (0x0+0x71d4) overlap CBFS data (0x5000)
E: Failed to create build/coreboot.pre1.tmp.
arm/snow offset is also enlarged and moved to Kconfig variable.

This patch moves ARM core and DRAM timing functions around to simplify
the dependencies for system_clock_init().
The original code was architected such that the system_clock_init()
function called other functions to obtain core and memory timings.
Due to the way memory timing information must be obtained on Snow,
which entails decoding platform-specific board straps, the bottom-
up approach resulted in having the low-level clock init code
implicitly depend on board and vendor-specific info:
main()
->system_clock_init()
-> get_arm_ratios()
-> CPU-specific code
-> clock_get_mem_timings()
-> board_get_revision()
-> read GPIOs (3-state logic)
-> Decode GPIOs in a vendor-specific manner
-> Choose memory timings from module-specific look-up table
...then proceed to init clocks
...come back to main()
The new approach gathers all board and vendor-specific info in a
more appropriate location and passes it into system_clock_init():
main()
-> get_arm_ratios()
-> CPU-specific code
-> get_mem_timings()
-> board_get_config()
-> read GPIOs (3-state logic)
-> Decode GPIOs in a vendor-specific manner
-> Choose memory timings from module-specific look-up table
-> system_clock_init()
...back to main()

Move the ID section again due to bootblock bloat. So long
as it's within the first 32K of our address space, we're good.
TODO:
1. Place ID section near start of ROM to avoid this issue.
2. Reduce bootblock bloat.
3. Make bootblock debugging a Kconfig option.

Right now cbfstool only accepts firmware volumes with
a x86 SEC core and refuses an x86-64 SEC core because
some magic values and the extended PE header are
different. With this patch, both IA32/x64 images are
supported. (No check is done whether the mainboard
actually supports 64bit CPUs, so careful!)
This needs another patch to Tiano Core that switches
to long mode after jumping to the 64bit entry point.
Right now that code assumes we're already in 64bit code
and the machine crashes.
