This board is based on the Marvell Orion5x SoC. Current support is limited to console and Flash. Flash support uses LEGACY as the Macronix 29LV400 used on ED Mini V2 is not 100% CFI compliant.
And the differences are really so big that we cannot tweak the CFI driver?
It's not CFI compliant. But you can use the legacy infrastructure in this driver, which meant to support such chips. Please take a look at the following driver:
drivers/mtd/jedec_flash.c
Your board config header would need something like this:
/* Use common CFI driver */ #define CONFIG_SYS_FLASH_CFI #define CONFIG_FLASH_CFI_DRIVER /* board provides its own flash_init code */ #define CONFIG_FLASH_CFI_LEGACY 1 #define CONFIG_SYS_FLASH_CFI_WIDTH FLASH_CFI_8BIT #define CONFIG_SYS_FLASH_LEGACY_512Kx8 1 ...
Taken from include/configs/hcu4.h. This should give you an idea...
Cheers, Stefan
Er... Precisely, I am using [CONFIG_FLASH_CFI_]LEGACY, as the patch comment says, though obviously not clearly enough.
Amicalement,
