The latest GCC is so clever that it reports more warnings

------------------------------>8------------------------------
board/freescale/m5253demo/flash.c: In function 'flash_get_offsets':
board/freescale/m5253demo/flash.c:65:23: warning: iteration 2047u

for (k = 0, j = 0; j < CONFIG_SYS_SST_SECT; j++, k++) {

------------------------------8<------------------------------
The cause of the warning is like this:
The for statement iterates 2048 times in flash_get_offsets() func.
(Notice CONFIG_SYS_SST_SECT is defined as 2048)
The last iteration does
info->start[2048] = info->start[2047] + CONFIG_SYS_SST_SECTSZ;
causing an undefined behavior.
(Please note the array size of info->start is 2048.
CONFIG_SYS_MAX_FLASH_SECT is defined as 2048 for this board.)
This commit fixes that so as not to overrun the info->start array.

In the earlier patches, the SPL/TPL fraamework was introduced.
For SD/SPI flash booting way, we introduce the SPL to enable a loader stub. The
SPL was loaded by the code from the internal on-chip ROM. The SPL initializes
the DDR according to the SPD and loads the final uboot image into DDR, then
jump to the DDR to begin execution.
For NAND booting way, the nand SPL has size limitation on some board(e.g.
P1010RDB), it can not be more than 4KB, we can call it "minimal SPL", So the
dynamic DDR driver doesn't fit into this minimum SPL. We added the TPL that is
loaded by the the minimal SPL. The TPL initializes the DDR according to the SPD
and loads the final uboot image into DDR,then jump to the DDR to begin execution.
This patch enabled SPL/TPL for P1_P2_RDB to support starting from NAND/SD/SPI
flash with SPL framework and initializing the DDR according to SPD in the SPL/TPL.
Because the minimal SPL load the TPL to L2 SRAM and the jump to the L2 SRAM to
execute, so the section .resetvec is no longer needed.

We only need u-boot to bother about a single core in the QEMU machine.
Everything that would require additional knowledge of more cores gets
handled by QEMU and passed straight into the payload we execute.
Because of this setup, it would be counterproductive to enable SMP support
in u-boot. We would have to rip CPUs out of already existing spin tables
and respin them from u-boot. It would be a pretty big mess.
So only assume we have a single core. This fixes errors about CONFIG_MP
being disabled.

The DRAM size can be easily detected at runtime on i.MX53. Implement
such detection on MX53QSB and adjust the rest of the macros accordingly
to use the detected values.
An important thing to note here is that we had to override the function
for trimming the effective DRAM address, get_effective_memsize(). That
is because the function uses CONFIG_MAX_MEM_MAPPED as the upper bound of
the available DRAM and we don't have gd->bd->bi_dram[0].size set up at
the time the function is called, thus we cannot put this into the macro
CONFIG_MAX_MEM_MAPPED . Instead, we use custom override where we use the
size of the first DRAM block which we just detected.
