From 63323ec54a7e922a232c82070727e44eb1a5b43c Mon Sep 17 00:00:00 2001 From: Manuel Lauss Date: Mon, 2 Nov 2009 21:21:43 +0100 Subject: MIPS: Alchemy: Extended DB1200 board support. Create own directory for DB1200 code and update it with new features. - SPI support: - tmp121 temperature sensor - SPI flash on DB1200 - I2C support - NE1619 sensor - AT24 eeprom - I2C/SPI can be selected at boot time via switch S6.8 - Carddetect IRQs for SD cards. - gen_nand based NAND support. - hexleds count sleep/wake transitions.
