Hello,
Here are fixes for the AST2600 SMC controller and the definition of a
new tacoma-bmc board using the AST2600 SoC.
Thanks,
C.

aspeed/smc: Restore default AHB window mapping at reset
aspeed/smc: Do not map disabled segment on the AST2600
aspeed/smc: Add AST2600 timings registers
aspeed: remove AspeedBoardConfig array and use AspeedMachineClass
aspeed: Add support for the tacoma-bmc board

The current model only restores the Segment Register values but leaves
the previous CS mapping behind. Introduce a helper setting the
register value and mapping the region at the requested address. Use
this helper when a Segment register is set and at reset.

The segments can be disabled on the AST2600 (zero register value).
CS0 is open by default but not the other CS. This is closing the
access to the flash device in user mode and forbids scanning.
In the model, check the segment size and disable the associated region
when the value is zero.

AspeedBoardConfig is a redundant way to define class attributes and it
complexifies the machine definition and initialization.
