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.

Call into k3-ddrss driver to fixup device tree and resize the available
amount of DDR if ECC is enabled.
A second fixup is required from A53 SPL to take the fixup as done from
R5 SPL and apply it to DT passed to A53 U-boot, which in turn passes
this to the OS.

The PMIC enables power to the MMC card by default, but depending
on the state it was left when restarted, it's possible the MMC
may be powered down.
This patch patch explicitly tells the twl4030 to power the MMC.

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.

With the exceptions of ds109, ds414, icnova-a20-swac, nokia_rx51 and
stemmy, disable ATAG support. A large number of platforms had enabled
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.

The PADCONFIG_202 register (0x02621328) is affected by the locking
of the RSTMUX8 register (0x02620328), and so cannot be configured
in kernel. This has been confirmed as a hardware bug and affects
all K2G SoCs.
Setup the pinmux for this pin before locking the RSTMUX8 register
to allow the ICSS1 PRU1 Ethernet PHY port to work properly. The
workaround was added only for the K2G-ICE board to configure the
pins needed for the PRUSS Ethernet usecase.

I2C-connected EEPROM describing itself.
This patch implements a generic extension_scan_board() feature that can

in the list of "extension" structures.
