From 3e326ece9eba8184f5d48aa4fb87760a8f6f0f10 Mon Sep 17 00:00:00 2001 From: Markus Klotzbuecher Date: Mon, 22 May 2006 16:33:54 +0200 Subject: This patch adds USB storage support for the delta board. This is the first board to make use of a generic OHCI driver, that calls hooks for board dependant initialization. --- include/asm-arm/arch-pxa/pxa-regs.h | 23 ++++++++++++++++++++++- 1 file changed, 22 insertions(+), 1 deletion(-) (limited to 'include/asm-arm') diff --git a/include/asm-arm/arch-pxa/pxa-regs.h b/include/asm-arm/arch-pxa/pxa-regs.h index ebda7192ed0..c47306cff28 100644 --- a/include/asm-arm/arch-pxa/pxa-regs.h +++ b/include/asm-arm/arch-pxa/pxa-regs.h @@ -592,9 +592,11 @@ typedef void (*ExcpHndlr) (void) ; #define PMC_REG_BASE __REG(0x40500400) /* Primary Modem Codec */ #define SMC_REG_BASE __REG(0x40500500) /* Secondary Modem Codec */ + /* * USB Device Controller */ +#ifndef CONFIG_CPU_MONAHANS #define UDC_RES1 __REG(0x40600004) /* UDC Undocumented - Reserved1 */ #define UDC_RES2 __REG(0x40600008) /* UDC Undocumented - Reserved2 */ #define UDC_RES3 __REG(0x4060000C) /* UDC Undocumented - Reserved3 */ @@ -749,11 +751,30 @@ typedef void (*ExcpHndlr) (void) ; #define USIR1_IR13 (1 << 5) /* Interrup request ep 13 */ #define USIR1_IR14 (1 << 6) /* Interrup request ep 14 */ #define USIR1_IR15 (1 << 7) /* Interrup request ep 15 */ +#endif /* !

Can't check if it works on SONATA, don't have a board any more, but it at least compiles. Here is an excerpt from session log on SCHMOOGIE...

NAND version is loaded by an initial + * bootloader (UBL in TI-ese) that performs such an initialization so it's + * skipped in NAND version. The third DaVinci boot mode loads a bootloader + * via UART0 and that bootloader in turn loads and runs U-Boot (or whatever) + * performing low level init prior to loading. All that means we can NOT use + * NAND version to put U-Boot into NOR because it doesn't have NOR support and + * we can NOT use NOR version because it performs low level initialization + * effectively destroying itself in DDR memory. That's why a separate NOR + * version with this define is needed. It is loaded via UART, then one uses + * it to somehow download a proper NOR version built WITHOUT this define to + * RAM (tftp?) and burn it to NOR Flash. I would be probably able to squeeze + * NOR support into the initial bootloader so it won't be needed but DaVinci + * static RAM might be too small for this (I have something like 2Kbytes left + * as of now, without NOR support) so this might've not happened... + * +#define CONFIG_NOR_UART_BOOT + */ + +/*=======*/ +/* Board */ +/*=======*/ +#define SONATA_BOARD +#define CFG_NAND_SMALLPAGE +#define CFG_USE_NOR +/*===================*/ +/* SoC Configuration */ +/*===================*/ +#define CONFIG_ARM926EJS /* arm926ejs CPU core */ +#define CONFIG_SYS_CLK_FREQ 297000000 /* Arm Clock frequency */ +#define CFG_TIMERBASE 0x01c21400 /* use timer 0 */ +#define CFG_HZ_CLOCK 27000000 /* Timer Input clock freq */ +#define CFG_HZ 1000 +/*====================================================*/ +/* EEPROM definitions for Atmel 24C256BN SEEPROM chip */ +/* on Sonata/DV_EVM board.
