d2ab2a2baf board: ti: common: board_detect: Fix EEPROM read quirk for AM6 style data
The situation is similar to commit bf6376642f ("board: ti: common:
board_detect: Fix EEPROM read quirk"). This is seen on a variant of
eeproms seen on some BeagleBone-AI64 which now has a mix of both 1 byte
addressing and 2 byte addressing eeproms.

Unlike the am335x (ti_i2c_eeprom_am_get) and dra7
(ti_i2c_eeprom_dra7_get) which use constant data structure which allows
us to do a complete read of the data, the
am6(ti_i2c_eeprom_am6_get) eeprom parse operation is dynamic.

This removes the option of being able to read the complete eeprom data
in one single shot.

Fortunately, on the I2C bus, we do see the following behavior: In 1
byte mode, if we attempt to read the first header data yet again, the
misbehaving 2 byte addressing device acts in constant addressing mode
which results in the header not matching up and follow on attempt at 2
byte addressing scheme grabs the correct data.

This costs us an extra ~3 milliseconds, which is a minor penalty
compared to the consistent image support we need to have.

bf6376642f board: ti: common: board_detect: Fix EEPROM read quirk
There are three different kinds of EEPROM possibly present on boards.
  1. 1byte address. For those we should avoid 2byte address in order
     not to rewrite the data. Second byte of the address can potentially
     be interpreted as the data to write.
  2. 2byte address with defined behaviour. When we try to use 1byte
     address they just return "FF FF FF FF ... FF"
  3. 2byte address with undefined behaviour (for instance, 24LC32AI).
     When we try to use 1byte address, then their internal read
     pointer is changed to some value. Subsequential reads may be
     broken.

To gracefully handle both case #1 and case #3 we read all required
data from EEPROM at once (about 80 bytes). So either all the data is
valid or we fallback to 2byte address.

a58147c2db board: ti: common: board_detect: Do 1byte address checks first.
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.

bc1de48371 board: ti: common: Handle the legacy eeprom address width properly
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.

Having a '.' in the section names conflicts with clang's ASAN

elements, causing expected accesses to fail. However, clang doesn't try
to add redzones to user sections, which are names with all alphanumeric

2f51f946e3 board: ti: am335x: eth_cpsw should depend on CONFIG_NET
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.

185f812c41 doc: replace @return by Return:
Sphinx expects Return: and not @return to indicate a return value.

609983e981 board: ti: am335x: Choose CPSW or PRUSS configuration based on jumper setting
The am335x-ice-v2 board's Ethernet ports can be configured
in 'MII' or 'RMII' mode to be connected to 'PRUSS' or 'CPSW'
Ethernet subsystems.

This patch sets the environment variable 'ice_mii' to
'mii' or 'rmii' accordingly. Based on that we choose the
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.
