post/i2c: Add ability to ignore I2C devices
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.

always relocate fdt into an lmb-allocated memory block
The device tree (fdt) must always exist in within the bootmap (usually the

an LMB region in the bootmap and copy the fdt into that region. It will
also increase the size of the fdt.
If the fdt is already in the bootmap, then previously the memory was just

Sometimes during upgrades or config changes, those limits are exceeded,
