Detailed Description

struct ec_response_flash_info_1 - Response to the flash info v1 command.

@flash_size: Usable flash size in bytes. @write_block_size: Write block size. Write offset and size must be a multiple of this. @erase_block_size: Erase block size. Erase offset and size must be a multiple of this. @protect_block_size: Protection block size. Protection offset and size must be a multiple of this. @write_ideal_size: Ideal write size in bytes. Writes will be fastest if size is exactly this and offset is a multiple of this. For example, an EC may have a write buffer which can do half-page operations if data is aligned, and a slower word-at-a-time write mode. @flags: Flags; see EC_FLASH_INFO_*

Version 1 returns the same initial fields as version 0, with additional fields following.

gcc anonymous structs don't seem to get along with the __packed directive; if they did we'd define the version 0 structure as a sub-structure of this one.

Version 2 supports flash banks of different sizes: The caller specified the number of banks it has preallocated (num_banks_desc) The EC returns the number of banks describing the flash memory. It adds banks descriptions up to num_banks_desc.
