From e3ba22db09408baee721897fb1b50e16f071d916 Mon Sep 17 00:00:00 2001 From: Andrew Victor Date: Sat, 24 May 2008 17:06:45 +0100 Subject: [PATCH] [ARM] 5056/1: [AT91] Cleanup YL9200 board file Cleanup the YL9200 board-support file. Other things fixed are: - Use new-style UART initialization - Register all LEDs as gpio_leds. - NOR Flash error noted in comments fixed by increasing YL9200_FLASH_SIZE - The only I2C device is the AT24C eeprom. - Setup of NWAIT pin and programming of SMC controller for the LCD/VGA. - Configure touchscreen interrupt pin. Also adding the board to the KConfig and Makefile.
