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 ++++++++++++++++++++++- include/configs/delta.h | 11 ++++++++++- include/da9030.h | 12 ++++++++++++ 3 files changed, 44 insertions(+), 2 deletions(-) (limited to 'include') 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 /* !

It could be triggered by building with TEXT_BASE set to a low value. However, this support is incomplete: using of low TEXT_BASE causes defining configuration macros in inconsistent way, which later leads to compilation errors. In particular. flash support is being disabled, but then flash structures get referenced. This patch fixes this, making it possible to build with low TEXT_BASE.

data declarations in .bss until afer code relocation) Improved SDRAM tests to catch problems where data is not uniquely addressable (e.g. incorrectly programmed SDRAM row or columns) Added CONFIG_PROG_SDRAM_TLB to support Bamboo SIMM/DIMM modules Fixed AM29LV320DT (OpCode Flash) sector map Signed-off-by: Eugene OBrien Signed-off-by: Stefan Roese --- board/amcc/bamboo/bamboo.c | 321

This means that the board header file should not define any CFG_SCCR macros for bitfields that don't exist on that processor, otherwise the SCCR will be programmed incorrectly.

Dirk Behme Date: Thu, 2 Aug 2007 17:41:14 +0200 Subject: Move 64bit division from avr32 to generic lib MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Move the 64bit division from lib_avr32 to lib_generic. With this, all boards can do_div/__div64_32 if needed, not only avr one. Code is put to lib_generic, so no larger memory footprint if not used. No code modifications. Thanks for proposal by Håvard Skinnemoen.

In the patch titled "Create new fdt boardsetup command..." I removed the call to ft_board_setup() from the routine fdt_chosen(), but I forgot to add a direct call back into cmd_bootm.c This fixes the oversight by adding the direct call to the bootm command.

Make the early L1 cache stack region guarded to prevent speculative fetches outside the locked range. Use _PHYS defines, not _MEM for cpu-side PCI memory mapped regions. init.S whitespace cleanup. Allow TEXT_BASE value to be specified on command line. This allows it to be set to 0xfffc0000 which cuts the uboot binary in half. Clear and enable lbc and ecm errors.

Merge to two at45.c files into a common file, split to at45.c and spi.c Fix spelling error in DM9161 PHY Support. Initialize at91rm9200 board (and set LED). Add PIO control for at91rm9200dk LEDs and Mux. Change dataflash partition boundaries to be compatible with Linux 2.6.
