So that the linux stm32_eth driver could be able to get it.

This will help us to debug support for ext 32 PSRAM. Now internal
RAM buffer has size of 88KB, and it's enough to put u-boot.bin there
for self-update purposes.

The problem in crashes while performing self-upgrade was that
".ramcode" envm_write_and_reset() was optimized to be inlined into
the flash-based do_cptf(). Removing "static" makes do_cptf() to do
the call.

There's no so much differences between different families of STM32.
Manual (migrate STM32F1 -> STM32F2) says, that GPIO and Flash are
significantly different, the other interfaces (we use) are almost
the same. So, let's name this arch as 'stm32', not 'stm32f2' (as we
do this in linux).

There's only one MAC controller in all STM32 products. No need to
have it regs 'mapped' in eth device structure (actually, there's
even no need in this structure at all - MAC is always one).

Don't declare & init local volatile pointer vars to access these
regs in each function, which need these. Use macros instead.

 However, a platform can implement their own reset_cpu().

Set console, passed to kernel by default, do ttyS2, which corresponds
to UART3. Unfortunatelly, there's no way to use UART1 (and ttyS0) on
this board, just because the GPIO pins used for RS-232 here in alter-
native functions have only UART3 and UART4 capabilities (btw, I tested
that being configured to use UART4 - U-Boot console works well too).

Also, fix-up platform configuration, and TFTP boot dir (in linux we'll
assume STM32 platform, not STM32F2 as we currently do in U-Boot).

Rationale: to support external RAM there'll be again (like in MAC)
a plenty of GPIOs which should be configured. Don't want to redfine
the GPIO descriptor structure (port + pin), let's have this struct
as a part of STM32F2 GPIO Driver API.
