Subject: [PATCH v2 0/4] spi: aspeed: Add AST2700 SoC support and Quad SPI handling update

This series adds AST2700 support to the ASPEED FMC/SPI driver and
bindings, introduces 64-bit address compatibility, and improves
Quad SPI page programming behavior. It also implements AST2700-specific
segment logic, where range adjustment is not required because the
AST2700 SPI hardware controller already fixes decoding issues on
the existing platforms and adopts an updated scheme.

Changes in v2:
  - Some differences between AST2600 and AST2700 are described in
    commit message of the dt-bindings patch.

Chin-Ting Kuo (4):
  dt-bindings: spi: aspeed,ast2600-fmc: Add AST2700 SoC support
  spi: aspeed: Enable Quad SPI mode for page program
  spi: aspeed: Use phys_addr_t for bus addresses to support 64-bit
    platforms
  spi: aspeed: Add support for the AST2700 SPI controller
