The MXC SPI driver didn't calculate the SPI clock up to
now and just used highest possible divider 512 for DATA
RATE in the control register. This results in very low
transfer rates.
The patch adds code to calculate and setup the SPI clock
frequency for transfers.

We need to shift only one time in each cycle in the swapping loop
for unaligned tx case. Currently two byte shift operations are
performed in each loop cycle causing zero gaps in the transmited
data, so not all data scheduled for transmition is actually
transmited.
The proper swapping in unaligned rx case is missing, so add it
as we need to put the received data into the rx buffer in the
correct byte order.

The patch adds helper funtions for basic access to the registers
of the MC9sdz60 chip (multifunctional device with RTC and CAN) via
I2C interface.
Signed-off-by: Stefano Babic <sbabic@denx.de>
There is sporadic failures when more as one I2C slave
is on the bus and the processor tries to communicate
with more as one slave.
The problem was seen on a mx35pdk (two I2C slaves,
PMIC controller and CAN/RTC chip).
The current driver uses the IIF bit in the status register
to check if the bus is busy or not. According to the manual,
this is not correct, because the IIB bit should be checked.
Not only, to check if a transfer is finished must be checked
the ICF bit, and this is not tested at all.
This patch comes from analyse with a corresponding driver
provided by Freescale as part of the LTIB tool. Comparing
the two drivers, it appears that the current u-boot driver checks
the wrong bits, and depending on race condition, the transfer
can be successful or not.
The patch gets rid also of own debug function (DPRINTF),
replaced with the general debug().
Tested on Freescale mx35pdk.

When building with srctree != objtree, the build creates arch/soc/cpu
specific symlinks in the source tree. This means that the same source
tree can't be used for multiple builds at the same time. Also, these
symlinks in the source tree are only cleaned up if one passes the same
O= to distclean.
When srctree != objtree, mkconfig creates an $objtree/include2 directory
in the objtree to host the asm -> arch/$arch/include/asm symlink so that
"#include <asm>" can be used. But it also creates another identical
symlink in $objtree/include.
Then, mkconfig creates two symlinks:
$objtree/include/asm/arch -> arch/$arch/include/asm/arch-$cpu (or $soc)
$objtree/include/asm/proc -> arch/$arch/include/asm/proc-armv (on arm)
but because $objtree/include/asm points at $srctree already, the two
symlinks are created under $srctree.
To fix this, create a real $objtree/include/asm directory, instead of a
symlink. Update cleanup code accordingly.

There are several users of the hwconfig APIs (8xxx DDR) before we have
the environment properly setup. This causes issues because of the
numerous ways the environment might be accessed because of the
non-volatile memory it might be stored in. Additionally the access
might be so early that memory isn't even properly setup for us.
Towards resolving these issues we provide versions of all the hwconfig
APIs that can be passed in a buffer to parse and leave it to the caller
to determine how to allocate and populate the buffer.
We use the _f naming convention for these new APIs even though they are
perfectly useable after relocation and the environment being ready.
We also now warn if the non-f APIs are called before the environment is
ready to allow users to address the issues.
Finally, we convert the 8xxx DDR code to utilize the new APIs to
hopefully address the issue once and for all. We have the 8xxx DDR code
create a buffer on the stack and populate it via getenv_f().
