Most code can be shared between i.MX23 and i.MX28 as both are from
i.MXS family; this source directory structure makes easy to share code
among them.

Exactly one board has defined CONFIG_SYS_PROMPT_HUSH_PS2 to a value
different than "> " which is vision2. I have Cc'd the maintainer here
as I strongly suspect this is a bug rather than intentional behavior.

We provide a default table of { 9600, 19200, 38400, 57600, 115200 }
in <config_fallbacks.h> which mkconfig places after <configs/...h> in
the generated config file. This is used when a board has not set its
own table.

The patch:
m28evk: Use GENERATED_GBL_DATA_SIZE
commit 1084606c97
introduced usage of GENERATED_GBL_DATA_SIZE and calculation of initial stack
pointer position defived from that. Due to a small typo, the SP position moved
to 0x21f80, which is past the SRAM area. This didn't manifest on the real
hardware as the SRAM repeats there (address bits in the CPU being ignored).
Though this was caught in QEMU, where it crashed the emulator.

The current way memsize.c is built just made a symlink into the directory
with SPL and then compiled it like any other file there. This was bad as that
broke the out-of-tree build.
The new way introduced in this patch uses the standard spl/Makefile methods
(CONFIG_SPL_LIBCOMMON_SUPPORT / CONFIG_SPL_LIBGENERIC_SUPPORT) to let files in
common/ be built. Because common/Makefile says memsize.c is always built (SPL
and non-SPL build), this fixes our issue with memsize.c out-of-tree build.

This patch introduces proper ARM vector handling for i.MX28 CPU. This issue
wasn't addressed because the interrupts weren't enabled on any ARMv5 core,
therefore the issue wasn't noticed earlier.
In previous implementation, the vectoring code used by i.MX28 CPU when an
exception happened was that of the SPL. With this change, the branch target when
an exception happens can be reconfigured by U-Boot.
