Create function which converts SSP bus number to SSP register pointer.
This functionality is reimplemented multiple times in the code, thus
make one common implementation. Moreover, make it a switch(), since the
SSP ports are not mapped in such nice linear fashion on MX23, therefore
having it a switch will simplify things there.

Move all the C runtime setup code from every start.S

to calling into board_init_r().
Also, rewrite the C runtime setup and make functions
board_init_*() and relocate_code() behave according to
normal C semantics (no jumping across the C stack any
more, etc).
Some SPL targets had to be touched because they use
start.S explicitly or for some reason; the relevant

This algorithm computes the values of TIMING{0,1,2} registers for the

The MMC driver appropriate for the i.MX25 is fsl_esdhc, which has nothing to do
with mxcmmc.
Also, each eSDHC instance has a dedicated clock, so gd->sdhc_clk must be set
accordingly. This is good for the case only a single SDHC instance is used
(initialization made with fsl_esdhc_mmc_init()). A future patch will fix the

For the DA8xx family of SoCs, the set_cpu_clk_info() function was not
initialising the DSP frequency, leading to 'bdinfo' command output such as:
[...snip...]
ARM frequency = 300 MHz
DSP frequency = -536870913 MHz
DDR frequency = 300 MHz
This commit provides a separate implementation of set_cpu_clk_info() for
the DA8xx SoCs that initialises the DSP frequency to zero (since
currently the DSP is not enabled by U-Boot on any DA8xx platform). The
separate implementation is justified because there is no common code
between DA8xx and the other SoC families. It is now much easier to
understand the flow of the two separate functions.

This solves issues when larger amount of DRAM is used, like 256MB.
Behave the same in case of CPU bypass as we do in case of EMI
bypass, but wait 15 ms. We need to wait until the clock domain
stabilizes.
This issue seemed to have been caused by not waiting after frobbing
with the CPU bypass, it was unrelated to memory, but had a direct
impact, causing trouble. This was yet another X-File of the
imx-bootlets, sigh. The conclusion is, trying a semi-random delay
(there is delay after the EMI bypass change), the issue is fixed.
Another possible explanation is that we do not do the "simple memory
test" FSL does in their imx-bootlets (1000 R/W cycles to/from piece of
the memory, while also outputing something on the serial port). This
might have caused the similar delay in the imx-bootlets and therefore
they didn't need to add this explicitly.
For now, this seems good fix enough, but to me, whole that memory
init code in imx-bootlets is completely flunked and it'd need deeper
investigation.

This reverts commit 69d26d09de.
Apparently, this commit got mainline only because of out-of-tree
port and causes breakage on board that is mainline. Revert.
Reason:
* The OOT board has 512MB of DRAM, enabling this additional address
line enabled it to work fine with 512MB of RAM.
* Every mainline port has max. 256MB of DRAM, therefore this revert
has no impact on any mainline port
* Though this caused a problem with new M28 board with 256MB of DRAM
where the chips are wired differently. The patch-to-be-reverted
caused the DRAM to behave like this:
[128MB chunk #1][128MB chunk #1 again][128MB chunk #2][128MB chunk #2 again]
Therefore to retain the current one-memory-init-rules-them-all situation,
revert this patch until another board emerges and will actually be pushed
mainline that needs different setup.

This fixes the issue where mxs_dma_init() was called either twice or never,
without introducing any new init hooks.
The idea is to allow each and every device using the APBH DMA block to
configure and request only the channels it uses, instead of making it call init
for all the channels as is now.
The common DMA block init part, which only configures the block, is then called
from CPUs arch_cpu_init() call.

This patch fixes booting i.MX28 CPUs via USB download.
In this mode the CPU's bootrom implements a USB HID device that
accepts a bootstream.
When downloading the bootstream via USB, first the SPL code is
received and executed. Then the u-boot image is received and
called.
The USB bootmode is interrupt driven.
This patch fixes two things:
1) The ARM's fast interrupt mode is disabled when the SPL code
has been run. So save and restore the CPSR register.
2) Save and restore c1 control register: the exception vector
location needs to be set back to bootrom space to make the USB
interrupts work again. The SPL code needs to change this
option for the ram size probing.

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

U-Boot Makefiles contain a number of tests for compiler features etc.
which so far are executed again and again. On some architectures
(especially ARM) this results in a large number of calls to gcc.
This patch makes sure to run such tests only once, thus largely
reducing the number of "execve" system calls.
Example: number of "execve" system calls for building the "P2020DS"
(Power Architecture) and "qong" (ARM) boards, measured as:
-> strace -f -e trace=execve -o /tmp/foo ./MAKEALL <board>
-> grep execve /tmp/foo | wc -l
Before: After: Reduction:
==================================
P2020DS 20555 15205 -26%
qong 31692 14490 -54%
As a result, built times are significantly reduced, typically by
30...50%.

Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils. As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".
This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.
The name of each former library archive is preserved except for
extensions which change from ".a" to ".o". This commit updates
references accordingly where needed, in particular in some linker
scripts.
This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols. Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

For ARM systems, before ELF relocation was introduced,
CONFIG_SKIP_RELOCATE_UBOOT coul be used to prevent *COPYING* the
U-Boot image from whereever it was loaded to it's link address
(CONFIG_SYS_TEXT_BASE). The name was badly chosen, as no relocation
was performed at all, it was just a memcpy().
With ELF relocation, this does not work like that any more, and

When this define was introduced, the idea was to provide a soft
migration path for ARM boards to get adapted to the new relocation
support. However, other recent changes led to a different
implementation (ELF relocation), where this no longer works. By now
CONFIG_SYS_ARM_WITHOUT_RELOC does not only not help any more, but it
actually hurts because it obfuscates the actual code by sprinkling it
with lots of dead and non-working debris.
So let's make a clean cut and drop CONFIG_SYS_ARM_WITHOUT_RELOC.

CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not

Recent experience has shown that manual synchronization is not
reliable enough. This patch renames CONFIG_SYS_GBL_DATA_SIZE into
GENERATED_GBL_DATA_SIZE which gets automatically generated by the
asm-offsets tool. In the result, all definitions of this value can be
deleted from the board config files. We have to make sure that all
files that reference such data include the new <asm-offsets.h> file.
