Do 1 byte address checks first prior to doing 2 byte address checks.
When performing 2 byte addressing on 1 byte addressing eeprom, the
second byte is taken in as a write operation and ends up erasing the
eeprom region we want to preserve.
While we could have theoretically handled this by ensuring the write
protect of the eeproms are properly managed, this is not true in case
where board are updated with 1 byte eeproms to handle supply status.
Flipping the checks by checking for 1 byte addressing prior to 2 byte
addressing check prevents this problem at the minor cost of additional
overhead for boards with 2 byte addressing eeproms.

Due to supply chain issues, we are starting to see a mixture of eeprom
usage including the smaller 7-bit addressing eeproms such as 24c04
used for eeproms.
These eeproms don't respond well to 2 byte addressing and fail the
read operation. We do have a check to ensure that we are reading the
alternate addressing size, however the valid failure prevents us
from checking at 1 byte anymore.
Rectify the same by falling through and depend on header data comparison
to ensure that we have valid data.

The eeprom data area is much bigger than the data we intend to store,
however, with bad programming, we might end up reading bad records over
and over till we run out of eeprom space. instead just exit when 10
consecutive records are read.

Rename the sections used to implement linker lists so they begin with
'__u_boot_list' rather than '.u_boot_list'. The double underscore at the
start is still distinct from the single underscore used by the symbol
names.
Having a '.' in the section names conflicts with clang's ASAN
instrumentation which tries to add redzones between the linker list
elements, causing expected accesses to fail. However, clang doesn't try
to add redzones to user sections, which are names with all alphanumeric
and underscore characters.

The origin of this patch is the breaking of am335x-hs boot
due to commit e41651fffd ("dm: Support parent devices with of-platdata")
HS boards have less SRAM for SPL and so this commit increased memory usage beyond am335x limit.
This commit added 10 driver binding pass and am335x boot only if one pass is done.
SPL try to do more than one pass due to eth_cpsw failing.
Since HS SPL does not need network (and NET is already disabled in config),
the easiest fix is to "remove" eth_cpsw from SPL by testing if NET is enabled.

Ethernet subsystems.
This patch sets the environment variable 'ice_mii' to

appropriate board devicetree i.e. 'am335x-ice-v2.dtb' or
'am335x-ice-v2-prueth.dtb'.
Since there are 2 Ethernet ports with 2 modes, there can be 4
configurations but for now we consider both ports in different modes
to be an invalid configuration and prevent boot in that case.

With the exceptions of ds109, ds414, icnova-a20-swac, nokia_rx51 and

support but never supported a kernel so old as to require it. Further,
some platforms are old enough to support both, but are well supported by
devicetree booting, and have been for a number of years. This is
because some of the ATAGs related functions have been re-used to provide
the same kind of information, but for devicetree or just generally to
inform the user. When needed still, rename these functions to
get_board_revision() instead, to avoid conflicts. In other cases, these
functions were simply unused, so drop them.
