Black Sesame Technologies C1200 is a high-performance Armv8 SoC designed for automotive
and industrial applications. The CDCU1.0 (Central Domain Control Unit) board is the
development platform built by Black Sesame Technologies. You can find more information
about the SoC and related boards at:
https://bst.ai

Currently, to run the upstream kernel on the CDCU1.0 board, you need to use the
bootloader provided by Black Sesame Technologies. The board supports various
interfaces including MMC/SD card, which is implemented using the BST C1200 DWCMSHC
SDHCI controller.

In this series, we add initial SoC and board support for kernel building. The series
includes:

Patch 1: Add Black Sesame Technologies vendor prefix in vendor-prefixes.yaml
- Adds "bst" vendor prefix for Black Sesame Technologies Co., Ltd.
- Required for device tree bindings to properly identify BST hardware

Patch 2: Add device tree bindings for BST SoC platforms
- Creates new binding file Documentation/devicetree/bindings/arm/bst.yaml
- Defines compatible strings for BST C1200 family and C1200 CDCU1.0 board
- Documents BST's focus on automotive-grade SoCs for ADAS applications

Patch 3: Add ARCH_BST configuration for BST silicon support
- Adds Kconfig option for BST architecture support
- Enables building kernel for BST platforms

Patch 4: Add device tree binding for BST DWCMSHC SDHCI controller
- Documents the BST C1200 SDHCI controller binding
- Required for MMC/SD card support on BST platforms

Patch 5: Add BST C1200 SDHCI controller driver
- Implements the MMC host controller driver for BST C1200
- Enables SD card support on BST platforms

Patch 6: Add device tree support for BST C1200 CDCU1.0 board
- Adds device tree source files for C1200 SoC and CDCU1.0 board
- Configures hardware components including MMC controller

Patch 7: Enable BST SoC in arm64 defconfig
- Adds ARCH_BST configuration to default arm64 config

Patch 8: Enable BST C1200 DWCMSHC controller in defconfig
- Enables MMC controller driver in default arm64 config

Patch 9: Update MAINTAINERS for BST support
- Adds maintainer information for BST ARM SoC support
- Consolidates BST-related entries
