[PATCH 0/2] SpacemiT K3 use 8gb memory size on CoM260 and Pico-ITX

[E Shattow]

Adjust from 16GiB to 8GiB memory size configuration on CoM260
and Pico-ITX for compatibility with 8GiB/16GiB/32GiB configurations.

It is expected that the bootloader will read EEPROM TLV value for
ID of the EEPROM part and adjust the device tree node accordingly.
In the simple case where adjustment is not performed however, then
the previous 16GiB range may overflow a 8GiB DRAM optioned board.

DeepComputing FML13v05 is sold in 16GiB/32GiB variants and not 8GiB
so it remains as 16GiB configuration.

[PATCH 1/2] riscv: dts: spacemit: k3: use com260 8gb memory configuration

[E Shattow]

The boot loader may override this configuration based on stored ID value
in EEPROM TLV and if it does not then the smallest common sold
configuration of 8gb is the most compatible option.
