Enumeration for IT51XXX flash extended operations.

Defines which flash device is accessed by IT51XXX flash controller, and the addressing mode for IT51XXX flash operations.

Enumerator
FLASH_IT51XXX_INTERNAL	Access the internal SPI e-flash. This operation targets the on-chip embedded SPI flash integrated inside the IT51XXX SoC.
FLASH_IT51XXX_EXTERNAL_FSPI_CS0	Access the external SPI flash connected to FSPI CS0#. This operation targets an external flash device connected to the IT51XXX FSPI controller chip select 0.
FLASH_IT51XXX_EXTERNAL_FSPI_CS1	Access the external SPI flash connected to FSPI CS1#. This operation targets an external flash device connected to the IT51XXX FSPI controller chip select 1.
FLASH_IT51XXX_ADDR_3B	3-byte (24-bit) addressing mode. This mode supports flash devices up to 16MB capacity, using 24-bit address cycles.
FLASH_IT51XXX_ADDR_4B	4-byte (32-bit) addressing mode. This mode supports larger flash devices (>16MB capacity), requiring 32-bit address cycles.
FLASH_IT51XXX_WRITE_PROTECT	Write protection.
FLASH_IT51XXX_READ_PROTECT	Read protection.
