Commit 7e263ce "post/i2c: Clean up detection logic" added a "const"
qualifier to the declaration of i2c_addr_list[], missing the fact that
the list gets modified later in the code, which results in build
errors like these:
i2c.c: In function 'i2c_post_test':

CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not
being able to use "sizeof(struct global_data)" in assembler files.
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.
No other changes have been done yet, but it is obvious that similar
changes / simplifications can be done for other, related macro
definitions as well.

A recurrent issue is that certain C level constructs like sizeof() or
offsetof() cannot be used in assembler files, which is inconvenient
when such constructs are used in the definition of macro names etc.
To avoid duplication of such definitions (and thus another cause of
problems), we adapt the Linux way to automatically generate the
respective definitions from the respective C header files.
In Linux, this is implemented in include/linux/kbuild.h, Kbuild, and
arch/*/kernel/asm-offsets.c; we adapt the code from the Linux v2.6.36
kernel tree.
We also copy the concept of the include/generated/ directory which can
be used to hold other automatically generated files as well.
We start with an architecture-independent lib/asm-offsets.c which
generates include/generated/generic-asm-offsets.h (included by
include/asm-offsets.h, which is what will be referred to in the actual
source code). Later this may be extended by architecture-specific
arch/*/lib/asm-offsets.c files that will generate a
include/generated/asm-offsets.h.

On OMAP36/37XX the standard on chip pullups are not sufficient to
ensure proper i2c operation without external pullups or switching
to high speed mode and enabling special on chip pullups.
This is an issue for Beagle xM, which does not have external pullups
on the expansion board i2c lines.
The issue manifests itself as an AL (arbitration lost) error when
probing for a non-existent device (i.e. on a Beagle xM with no expansion
boards attached). This issue does not occur on expansion boards that
include pullups or on Overo 37XX COM's since they include pull-ups.
This patch fixes the issue by checking for the AL bit in the i2c_probe
function.

Since we use hwconfig in cases before relocation (like getting DDR
params on FSL PPC systems), we can have strings that exceed the early
small (32 byte) buffer size that getenv will handle.
So we explicitly allocate our own buffer on the stack and use if to
handle getting the hwconfig env string. We currently utilize a string
length of 128 bytes.
This allows us to get rid of boot messages like:

This patch adds CONFIG_SYS_FLASH_BANKS_SIZES define to make use of new
cfi_flash driver ability to detect flash chips that are bigger than a
corresponding address window (we have such situation on some revs of
a4m072).
Signed-off-by: Ilya Yanok <yanok@emcraft.com>
On some boards we have flash mapped high in the address space with
considerably small window (say 0xFE000000 and 32MB). When we install
bigger chip (say 64MB) on such a board strange things happen
(flash_write() doesn't work at all, for ex). That's because cfi_flash
driver doesn't care about window size at all.
Of course, cleanest solution would probably be to just extend address
window to be able to map the whole flash but for legacy/compatibility
reasons some people prefer just truncate the flash size and never use
the upper part.
This patch adds an option for cfi_flash driver to handle this situation
properly. To achieve this we add the new function cfi_flash_bank_size()
which can be provided by the board code and weak-aliased to default
implementation that returns value from the CONFIG_SYS_FLASH_BANKS_SIZES
array if it's defined or 0 otherwise (the last case is added for
compatibility).
If non-zero flash bank size is provided and detected chip size is bigger
than provided address window size the warning will be displayed and
flash chip will be truncated.

This patch solves a problem with USB hanging under higher load on a
i.MX31 board. It falls into class of typical USB problems and fixes:
if you don't understand the real cause, add a delay somewhere.
The problem appeared after introduction of ELF relocation, which
results in smaller code, which appears to run faster (probably because
it fits better in the cache); turning off the instruction cache,
adding debug printf()s and increasing the delay have all been found to
make the problem go away.
Moving the original "udelay(1)" up in the code to it's new place made
the problem appear much less frequently. Increasing the delay to 2
microseconds then made the code run reliably in all (hour-long) tests.
To be on the safe side, we set it to 5 microseconds here.

Add the ability to not report an I2C POST error for a set of given I2C
addresses on bootup. This is useful for cases when a device may or may
not be present, and neither case is considered an error. For example:
- Some form factors such as XMC and Compact PCI Express have an I2C
EEPROM whose address changes based on geographical address. Eg
installed in one slot its EEPROM address is, 0x50, in another its
0x51, etc. This allows multiple devices to have their EEPROMs present
on the same I2C bus. Thus the I2C devices present for an XMC or
CPCIe card depend on if and where other cards are installed in the
same system.
- Some cards have optional I2C devices. Eg one hardware build
configuration has different I2C devices than another and software
can't determine if the optional device should be present or not.
- Some cards have optional daughtercards with I2C devices on them.
- I2C EEPROMs address range depends on their size. Its possible to
support differently size EEPROMs by only probing the EEPROM's base
address and ignoring the other addresses that are impacted by its
size.
A new CONFIG_SYS_POST_I2C_IGNORES define has been added which specifies
a list of I2C addresses for the I2C POST to ignore.

According to the I2C specification device address 0 is the "general call
address", ie a broadcast address. The I2C specification states that the
format of a general call uses at least 2 bytes, which U-Boot's probing
routine does not adhere to.
Not probing device address 0 will prevent possible issues with devices
that accept general calls. Additionally, this change shouldn't reduce
POST coverage since each I2C device should still be accessed via its
own, unique address.
