The DRAM size can be easily detected at runtime on i.MX53. Implement
such detection on M53EVK 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.

Fix memory access slowness on i.MX53 M53EVK board. Let us inspect the
issue: First of all, the i.MX53 CPU has two memory banks mapped at
0x7000_0000 and 0xb000_0000 and each of those can hold up to 1GiB of
DRAM memory. Notice that the memory area is not continuous. On M53EVK,
each of the banks contain 512MiB of DRAM, which makes a total of 1GiB
of memory available to the system.
The problem is how the relocation of U-Boot is treated on i.MX53 . The
U-Boot is placed at the ((start of first DRAM partition) + (gd->ram_size)) .
This in turn poses a problem, since in our case, the gd->ram_size is 1GiB,
the first DRAM bank starts at 0x7000_0000 and contains 512MiB of memory.
Thus, with this algorithm, U-Boot is placed at offset:
0x7000_0000 + 1GiB - sizeof(u-boot and some small margin)
This is past the DRAM available in the first bank on M53EVK, but is still
within the address range of the first DRAM bank. Because of the memory
wrap-around, the data can still be read and written to this area, but the
access is much slower.
There were two ideas how to solve this problem, first was to map both of
the available DRAM chunks next to one another by using MMU, second was to
define CONFIG_VERY_BIG_RAM and CONFIG_MAX_MEM_MAPPED to size of the memory
in the first DRAM bank. We choose the later because it turns out the former
is not applicable afterall. The former cannot be used in case Linux kernel
was loaded into the second DRAM bank area, which would be remapped and one
would try booting the kernel, since at some point before the kernel is started,
the MMU would be turned off, which would destroy the mapping and hang the
system.

access is much slower.
There were two ideas how to solve this problem, first was to map both of
the available DRAM chunks next to one another by using MMU, second was to
define CONFIG_VERY_BIG_RAM and CONFIG_MAX_MEM_MAPPED to size of the memory
in the first DRAM bank. We choose the later because it turns out the former
is not applicable afterall. The former cannot be used in case Linux kernel
was loaded into the second DRAM bank area, which would be remapped and one
would try booting the kernel, since at some point before the kernel is started,
the MMU would be turned off, which would destroy the mapping and hang the
system.

Use of PCIe on SABRE Lite and Nitrogen6x boards
is atypical and requires the use of custom daughter
boards.
Use in U-Boot is even rarer, so this patch removes it from
the standard configuration.

Add yet another OCOTP driver for this i.MX family. This time, it's a driver for
the OCOTP variant found in the i.MX23 and i.MX28. This version of OCOTP is too
different from the i.MX6 one that I could not use the mxc_ocotp.c driver without
making it into a big pile of #ifdef . This driver implements the regular fuse
command interface, but due to the IP blocks' limitation, we support only READ
and PROG functions.

When using HAB, there are additional special requirements on the placement of
U-Boot and the U-Boot SPL in memory. To fullfill these, this patch moves the
U-Boot binary a little further from the begining of the DRAM, so the HAB CST
and IVT can be placed in front of the U-Boot binary. This is necessary, since
both the U-Boot and the IVT must be contained in single CST signature. To
make things worse, the IVT must be concatenated with one more entry at it's
end, that is the length of the entire CST signature, IVT and U-Boot binary
in memory. By placing the blocks in this order -- CST, IVT, U-Boot, we can
easily align them all and then produce the length field as needed.
As for the SPL, on i.MX23/i.MX28, the SPL size is limited to 32 KiB, thus
we place the IVT at 0x8000 offset, CST right past IVT and claim the size
is correct. The HAB library accepts this setup.
Finally, to make sure the vectoring in SPL still works even after moving
the SPL from 0x0 to 0x1000, we add a small function which copies the
vectoring code and tables to 0x0. This is fine, since the vectoring code
is position independent.

In the recent mmc cleanup, the mmc_host_is_spi macro was broken and
bfin_sdh.c had mmc->bus_width turned into mmc_bus_width(mmc), both of
which were incorrect.

New configs:
- CONFIG_LIB_RAND - to enable implementation of rand library in lib/rand.c
- CONFIG_LIB_HW_RAND - to enable hardware based implementations of lib rand
Other changes:
- add CONFIG_LIB_RAND to boards configs which needs rand()
- put only one rand.o dependency in lib/Makefile
CONFIG_LIB_HW_RAND should be defined for drivers which implements rand library
(declared in include/common.h):
- void srand(unsigned int seed)
- unsigned int rand(void)
- unsigned int rand_r(unsigned int *seedp)

The way that struct mmc was implemented was a bit of a mess;
configuration and internal state all jumbled up in a single structure.
On top of that the way initialization is done with mmc_register leads
to a lot of duplicated code in drivers.
Typically the initialization got something like this in every driver.
struct mmc *mmc = malloc(sizeof(struct mmc));
memset(mmc, 0, sizeof(struct mmc);
/* fill in fields of mmc struct */
/* store private data pointer */
mmc_register(mmc);
By using the new mmc_create call one just passes an mmc config struct
and an optional private data pointer like this:
struct mmc = mmc_create(&cfg, priv);
All in tree drivers have been updated to the new form, and expect
mmc_register to go away before long.
Changes since v1:
* Use calloc instead of manually calling memset.
* Mark mmc_register as deprecated.
