TWR-P1025 Specification:
-----------------------
Memory subsystem:
512MB DDR3 (on board DDR)
64Mbyte 16bit NOR flash
One microSD Card slot
Ethernet:
eTSEC1: Connected to Atheros AR8035 GETH PHY
eTSEC3: Connected to Atheros AR8035 GETH PHY
UART:
Two UARTs are routed to the FDTI dual USB to RS232 convertor
USB: Two USB2.0 Type A ports
I2C:
AT24C01B 1K Board EEPROM (8 bit address)
QUICC Engine:
Connected to DP83849i PHY supply two 10/100M ethernet ports
QE UART for RS485 or RS232
PCIE:
One mini-PCIE slot

Is there really a need for supporting both 32-bit and 36-bit address
maps here? How much RAM does the board have, and is it pluggable or
soldered? If it's pluggable, you really should use SPD...

You should be done executing from flash here, so remove SX. The
guarded bit won't prevent speculative instruction fetches.

Why is it in the dts (and not disabled) in the first place? Do you not
have a separate dts for twr_p1025?

As above, don't put MAS3_SX on I/O TLB entries.

L2 SRAM, not L2 SDRAM. Move it to the cacheable section (or remove the
cacheable/non-cacheable split), and remove the nonsense "SRAM YZ M"
entry and the TBD.

Only 256 KiB? We tend to exceed that, and it's easier to reserve 512
KiB now than to change it later when people want to turn on more
features.
How large is the U-Boot binary now?

Shouldn't "_32b" depend on whether this is a 36-bit U-boot?

Use mtdparts if you want to specify partition information here.

Use && rather than ; so that we don't attempt to boot if tftp fails.
