Rename populate_serial_number() to a more descriptive
serial_read_from_eeprom() and provide the missing function prototype.
This is useful for boards that wish to read their serial number from
EEPROM at init.

Move the handler for "tlv_eeprom dev X" command to the beginning of
do_tlv_eeprom, to allow using it before issuing a "read" command for
currently selected eeprom.
Also remove the check if eeprom exists, since that can only work after
the first execution of read_eeprom triggered device lookup.
Instead accept values up to the defined array size (MAX_TLV_DEVICES).

When tlv eeprom does not exist, return error code instead of quietly
making up tlv structure in memory.

has_been_read is only used as an optimization for do_tlv_eeprom.
Explicitly use and set inside this function, thus making read_eeprom
stateless.

A command called with incorrect parameters should set $? to 1 (false).
Instead of calling cmd_usage(cmdtp) and then returning 0 just return
CMD_RET_FAILURE.

It is a pain to have to specify the value 16 in each call. Add a new
hextoul() function and update the code to use it.
Add a proper comment to simple_strtoul() while we are here.

Move this out of the common header and include it only where needed. In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly. Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.
Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.
This requires quite a few header-file additions.

Move this header out of the common header. Network support is used in
quite a few places but it still does not warrant blanket inclusion.
Note that this net.h header itself has quite a lot in it. It could be
split into the driver-mode support, functions, structures, checksumming,
etc.

Add support for read/write of ONIE "Tlvinfo" EEPROM data format. TLV
stands for Type-Length-Value. The data format is described here:
https://opencomputeproject.github.io/onie/design-spec/hw_requirements.html#board-eeprom-information-format
Based on U-Boot patch from the Open Compute project:
ec87e872d4/patches/u-boot/common/feature-sys-eeprom-tlv-common.patch
Keep only I2C EEPROM support. Use the generic eeprom driver. Fix
checkpatch issues.
Add support for multiple EEPROM TLV stores on the same system. This is
useful in case of SOM and carrier that both provide ID and hardware
configuration information.
Add option to enable for SPL. This allows selection of RAM configuration
based on EEPROM stored board identification.
