Flash cfi driver

This option enables JEDEC-style probing of flash chips which are not compatible with the Common Flash Interface, but will use the common CFI-targeted flash drivers for any chips which are identified which are in fact compatible in all but the probe method. If not, start detecting with 8bit. */ #ifndef CONFIG_SYS_FLASH_CFI_WIDTH #define CONFIG_SYS_FLASH_CFI_WIDTH FLASH_CFI_8BIT #endif #ifdef CONFIG_CFI_FLASH_USE_WEAK_ACCESSORS #define __maybe_weak __weak #else #define __maybe_weak static #endif /* * 0xffff is an undefined value for the configuration. The READ CFI QUERY command reads data from the common flash interface (CFI), blocks, the Flash device driver interface will always refer to the block with address offset 0 as block number 0, and to the last block as block number With the software driver interface, users can focus on writing the high-level code re-.

The Common Flash Memory Interface (CFI) is an open standard jointly developed by AMD, Intel, Sharp and Fujitsu. It is implementable by all flash memory vendors, and has been approved by the non-volatile-memory subcommittee of JEDEC. The goal of the specification is the interchangeability of flash memory devices offered by different vendors. If not, start detecting with 8bit. */ #ifndef CONFIG_SYS_FLASH_CFI_WIDTH #define CONFIG_SYS_FLASH_CFI_WIDTH FLASH_CFI_8BIT #endif #ifdef CONFIG_CFI_FLASH_USE_WEAK_ACCESSORS #define __maybe_weak __weak #else #define __maybe_weak static #endif /* * 0xffff is an undefined value for the configuration. Flash Driver: cfi The “Common Flash Interface” (CFI) is the main standard for external NOR flash chips, each of which connects to a specific external chip select on the CPU. Frequently the first such chip is used to boot the system.
