| Subject: [PATCH u-boot v2016.07-aspeed-openbmc] Add MTD support to Aspeed Flash driver |
| |
| Add support to the aspeed flash driver to enable the common mtd layer |
| through CONFIG_FLASH_CFI_MTD. |
| |
| This enables the flash to be used by u-boot mtd drivers including |
| the mtdparts and ubi commands. |
