values. With these settings both our reworked ST-MEM cards works.

This reverts commit 1ddfff86.

Also, enabled CONFIG_MISC_INIT_R to set the non-default flash timings.

(BWR - > BWTR).

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.

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).

Note, beside this, to make driver workable, this patch:

- changes SRAM memory distribution. Actually, we have 128K in STM (as
opposite to 64K in A2F). TBDs here: a) CONFIG_MEM_RAM_LEN is a bad
name, since this isn't length of full SRAM, but just a part of it; b)
we should control the summary length of MEM_xxx areas somehow, on a
SOC basis (i.e. A2F has 64K SRAM, STM32F2 has 128K SRAM, etc.), maybe
include/configs/cortex-m3-common.h would be the best choice; c) not
sure if we want to have *all* SRAM parts configurable, e.g. MALLOC size
may be determined automatically.

- in default configuration load files to SRAM (RAM_BUF) (as opposite
to external RAM). TBD here: make this configurable somehow.

Beside of faster working we'll need HSE for clocking MAC (previously
we was clocked by HSI, by poweron default).

Use this driver to configure GPIOs for using them:
- with UART (right now);
- with Ethernet (in the forthcoming patches).

Note, this patch also:
- removes the gap between RAM_BUF and MALLOC (additional 4K are
  used for MALLOC now: 8K -> 12K);
- exports memory layout via _mem_xxx symbols, so:
-- use _mem_ram_buf_xxx in cmd_cptf.c instead of hard-coded vals;
-- use _mem_stack_xxx instead of armboot_start;
-- use _mem_stack_end in start.c instead of hard-coded val.
