This patch series adds initial support for the SpacemiT K3 BS01DCMA
board, which is equipped with a K3 SoC, 16 GiB of LPDDR5 memory, a P1
PMIC, an EEPROM and QSPI NOR flash.

Enable support for the serial console, EEPROM, PMIC and QSPI NOR flash.

BS01DCMA is a board based on the SpacemiT K3 SoC. Add its compatible
with the K3 SoC fallback.

Hi Troy,

Thanks for the patch!

I just had a talk with Dong from Spacemit. He tells me the BS01DCMA is
the name of a module similar to the com260, only it has a different
form factor and each module consists of 2 separate K3 nodes. Similar
to how the com260 module can be used in a small carrier board
(spacemit,k3-com260-ifx) and in a 10-node server
(spacemit,k3-com260-tq), I'd expect to see a
common arch/riscv/boot/dts/spacemit/k3-bs01dcma.dtsi describing the
module itself, and then an
arch/riscv/boot/dts/spacemit/k3-bs01dcma-<something>.dts that
describes the extra peripherals that can be accessed when the module
is plugged into the server.

Unfortunately Dong didn't yet give me the name of the server using the
BS01DCMA modules that they showcased in Shenzhen.
