arm: mx5: Fix memory slowness on MX53QSB
Fix memory access slowness on i.MX53 MX53QSB 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 MX53QSB,
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 MX53QSB, 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.

arm: mxs: Add support for generating signed BootStream
This patch adds the groundwork for generating signed BootStream, which
can be used by the HAB library in i.MX28. We are adding a new target,
u-boot-signed.sb , since the process for generating regular non-signed
BootStream is much easier. Moreover, the signed bootstream depends on
external _proprietary_ _binary-only_ tool from Freescale called 'cst',
which is available only under NDA.
To make things even uglier, the CST or HAB mandates a kind-of circular
dependency. The problem is, unlike the regular IVT, which is generated
by mxsimage, the IVT for signed boot must be generated by hand here due
to special demands of the CST. The U-Boot binary (or SPL binary) and IVT
are then signed by the CST as a one block. But here is the problem. The
size of the entire image (U-Boot, IVT, CST blocks) must be appended at
the end of IVT. But the size of the entire image is not known until the
CST has finished signing the U-Boot and IVT. We solve this by expecting
the CST block to be always 3904B (which it is in case two files, U-Boot
and the hand-made IVT, are signed in the CST block).

arm: mxs: Adjust the load address of U-Boot and SPL for HAB
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.
