3511b92d31 Samsung CPUs: Unify Kconfig
For all other CPUs, we unconditionally include the CPU Kconfig
files in the CPU directory, not in the vendor directory. Do the
same thing for the Exynos CPUs. This allows us to make CPU dependent
changes in the directory of that CPU alone.
Also, drop some unused Kconfig variables from the Exynos Kconfig
files.

fbb11cf979 ARM: Separate the early console (romstage) from the bootblock console.
It might be that you want an early console in romstage before RAM is up, but
you can't or don't want to support the console all the way back in the
bootblock. By making the console in those two different environments
configurable seperately that becomes possible.

On the 5250 console output as early as the bootblock works, but on the 5420 it
only starts working in the ROM stage after clocks have been initialized.

607c0b6d63 pit: Create an exynos5420 directory which is nearly a copy of exynos5250.
This change creates an exynos5420 directory with code that will eventually
implement support for the exynos5420 cpu from Samsung. Currently it's a copy
of the exynos5250 directory with the name changed. There are going to be some
problems where headers in src/cpu/samsung/exynos-common include headers in the
exynos5250 directory directly.

We have the monotonic timer implemented on exynos now, and this
also enables helpful bootstage prints with timing info.

f7fcb2056f console: Always allow setting "EARLY_CONSOLE" configuration.
Early console should always be allowed to be turned on / off (for generating
production and debug versions), and should not be enforced by "select" Kconfig
rule.

A new "DEFAULT_EARLY_CONSOLE" is introduced for devices to select if they
prefer early console output by default.

Verified Kconfig value on qemu/x86 (default y by CACHE_AS_RAM), snow/x86
(default y by EXYNOS5 config), and intel/jarrell (default n).

ad173ea70b console: Revise serial console configuration names.
The console drivers (especially serial drivers) in Kconfig were named in
different styles. This change will rename configuration names to a better naming
style.

 - EARLY_CONSOLE:
        Enable output in pre-ram stage. (Renamed from EARLY_SERIAL_CONSOLE
        because it also supports non-serial)

 - CONSOLE_SERIAL:
        Enable serial output console, from one of the serial drivers. (Renamed
        from SERIAL_CONSOLE because other non-serial drivers are named as
        CONSOLE_XXX like CONSOLE_CBMEM)

 - CONSOLE_SERIAL_UART:
	Device-specific UART driver. (Renamed from
	CONSOLE_SERIAL_NONSTANDARD_MEM because it may be not memory-mapped)

 - HAVE_UART_SPECIAL:
        A dependency for CONSOLE_SERIAL_UART.

Verified to boot on x86/qemu and armv7/snow, and still seeing console
messages in romstage for both platforms.

6a503b6a0f make early serial console support more generic
This patch makes pre-RAM serial init more generic, particularly for
platforms which do not necessarily need cache-as-RAM in order to use
the serial console and do not have a standard 8250 serial port.

This adds a Kconfig variable to set romstage-* for very early serial
console init. The current method assumes that cache-as-RAM should
enable this, so to maintain compatibility selecting CACHE_AS_RAM will
also select EARLY_SERIAL_CONSOLE.

The UART code structure needs some rework, but the use of ROMCC,
romstage, and then ramstage makes things complex.

uart.h now includes all .h files for all uarts. All 2 of them.
This is actually a simplifying change.

f1dfb2eb94 move iRAM config variable to exynos5250 Kconfig
Since these don't seem very generic and depend on the BL1, let's
move them to the CPU-specific Kconfig.

9fe20cb381 WIP: Initial support for Samsung Exynos 5250 ARM CPU
Samsung SoC files, including Exynos5 (a Cortex-A15
implementation). Since this is an SoC we'll forego the x86-style
{north,south}bridge and cpu distinction. We may try to split some
stuff out before the final version if prudent.
