[U-Boot] [PATCH] Add AMD 29LV160DB FLASH support to SBC2410 board.

Tue Dec 30 08:47:03 CET 2008


The new SBC-2410A board from Embest now ships with 2MB NOR FLASH,
for which CONFIG_AMD_LV160 has been defined in include/configs/sbc2410x.h

This chip is already supported in other architectures, so AMD_ID_LV160B
has been used as-is in board/sbc2410x/flash.c
