From 92558d67a463bfbb351d30e28648de03b635f024 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Thu, 6 Sep 2007 16:27:37 +0000 Subject: strip the kernel version suffix from target directories, except for brcm-2.4 (the -2.4 will be included in the board name here). CONFIG_LINUX__ becomes CONFIG_TARGET_, same for profiles. git-svn-id: svn://svn.openwrt.org/openwrt/trunk@8653 3c298f89-4303-0410-b956-a3cf2f4a3e73 --- .../rb532/files/include/asm-mips/rc32434/dma.h | 168 +++++++++++++++++++++ 1 file changed, 168 insertions(+) create mode 100644 target/linux/rb532/files/include/asm-mips/rc32434/dma.h (limited to 'target/linux/rb532/files/include/asm-mips/rc32434/dma.h') diff --git a/target/linux/rb532/files/include/asm-mips/rc32434/dma.h b/target/linux/rb532/files/include/asm-mips/rc32434/dma.h new file mode 100644 index 0000000000..2124f7e510 --- /dev/null +++ b/target/linux/rb532/files/include/asm-mips/rc32434/dma.h @@ -0,0 +1,168 @@ +#ifndef __IDT_DMA_H__ +#define __IDT_DMA_H__ + +/******************************************************************************* + * + * Copyright 2002 Integrated Device Technology, Inc. + * All rights reserved. + * + * DMA register definition. + * + * File : $Id: dma.h,v 1.3 2002/06/06 18:34:03 astichte Exp $ + * + * Author : ryan.holmQVist@idt.com + * Date : 20011005 + * Update : + * $Log: dma.h,v $ + * Revision 1.3 2002/06/06 18:34:03 astichte + * Added XXX_PhysicalAddress and XXX_VirtualAddress + * + * Revision 1.2 2002/06/05 18:30:46 astichte + * Removed IDTField + * + * Revision 1.1 2002/05/29 17:33:21 sysarch + * jba File moved from vcode/include/idt/acacia + * + * + ******************************************************************************/ + +enum +{ + DMA0_PhysicalAddress = 0x18040000, + DMA_PhysicalAddress = DMA0_PhysicalAddress, // Default + + DMA0_VirtualAddress = 0xb8040000, + DMA_VirtualAddress = DMA0_VirtualAddress, // Default +} ; + +/* + * DMA descriptor (in physical memory). + */ + +typedef struct DMAD_s +{ + u32 control ; // Control. use DMAD_* + u32 ca ; // Current Address. + u32 devcs ; // Device control and status. + u32 link ; // Next descriptor in chain. +} volatile *DMAD_t ; + +enum +{ + DMAD_size = sizeof (struct DMAD_s), + DMAD_count_b = 0, // in DMAD_t -> control + DMAD_count_m = 0x0003ffff, // in DMAD_t -> control + DMAD_ds_b = 20, // in DMAD_t -> control + DMAD_ds_m = 0x00300000, // in DMAD_t -> control + DMAD_ds_ethRcv_v = 0, + DMAD_ds_ethXmt_v = 0, + DMAD_ds_memToFifo_v = 0, + DMAD_ds_fifoToMem_v = 0, + DMAD_ds_pciToMem_v = 0, + DMAD_ds_memToPci_v = 0, + + DMAD_devcmd_b = 22, // in DMAD_t -> control + DMAD_devcmd_m = 0x01c00000, // in DMAD_t -> control + DMAD_devcmd_byte_v = 0, //memory-to-memory + DMAD_devcmd_halfword_v = 1, //memory-to-memory + DMAD_devcmd_word_v = 2, //memory-to-memory + DMAD_devcmd_2words_v = 3, //memory-to-memory + DMAD_devcmd_4words_v = 4, //memory-to-memory + DMAD_devcmd_6words_v = 5, //memory-to-memory + DMAD_devcmd_8words_v = 6, //memory-to-memory + DMAD_devcmd_16words_v = 7, //memory-to-memory + DMAD_cof_b = 25, // chain on finished + DMAD_cof_m = 0x02000000, // + DMAD_cod_b = 26, // chain on done + DMAD_cod_m = 0x04000000, // + DMAD_iof_b = 27, // interrupt on finished + DMAD_iof_m = 0x08000000, // + DMAD_iod_b = 28, // interrupt on done + DMAD_iod_m = 0x10000000, // + DMAD_t_b = 29, // terminated + DMAD_t_m = 0x20000000, // + DMAD_d_b = 30, // done + DMAD_d_m = 0x40000000, // + DMAD_f_b = 31, // finished + DMAD_f_m = 0x80000000, // +} ; + +/* + * DMA register (within Internal Register Map). + */ + +struct DMA_Chan_s +{ + u32 dmac ; // Control. + u32 dmas ; // Status. + u32 dmasm ; // Mask. + u32 dmadptr ; // Descriptor pointer. + u32 dmandptr ; // Next descriptor pointer. +}; + +typedef struct DMA_Chan_s volatile *DMA_Chan_t ; + +//DMA_Channels use DMACH_count instead + +enum +{ + DMAC_run_b = 0, // + DMAC_run_m = 0x00000001, // + DMAC_dm_b = 1, // done mask + DMAC_dm_m = 0x00000002, // + DMAC_mode_b = 2, // + DMAC_mode_m = 0x0000000c, // + DMAC_mode_auto_v = 0, + DMAC_mode_burst_v = 1, + DMAC_mode_transfer_v = 2, //usually used + DMAC_mode_reserved_v = 3, + DMAC_a_b = 4, // + DMAC_a_m = 0x00000010, // + + DMAS_f_b = 0, // finished (sticky) + DMAS_f_m = 0x00000001, // + DMAS_d_b = 1, // done (sticky) + DMAS_d_m = 0x00000002, // + DMAS_c_b = 2, // chain (sticky) + DMAS_c_m = 0x00000004, // + DMAS_e_b = 3, // error (sticky) + DMAS_e_m = 0x00000008, // + DMAS_h_b = 4, // halt (sticky) + DMAS_h_m = 0x00000010, // + + DMASM_f_b = 0, // finished (1=mask) + DMASM_f_m = 0x00000001, // + DMASM_d_b = 1, // done (1=mask) + DMASM_d_m = 0x00000002, // + DMASM_c_b = 2, // chain (1=mask) + DMASM_c_m = 0x00000004, // + DMASM_e_b = 3, // error (1=mask) + DMASM_e_m = 0x00000008, // + DMASM_h_b = 4, // halt (1=mask) + DMASM_h_m = 0x00000010, // +} ; + +/* + * DMA channel definitions + */ + +enum +{ + DMACH_ethRcv = 0, + DMACH_ethXmt = 1, + DMACH_memToFifo = 2, + DMACH_fifoToMem = 3, + DMACH_pciToMem = 4, + DMACH_memToPci = 5, + + DMACH_count //must be last +}; + + +typedef struct DMAC_s +{ + struct DMA_Chan_s ch [DMACH_count] ; //use ch[DMACH_] +} volatile *DMA_t ; + +#endif // __IDT_DMA_H__ + -- cgit v1.2.3
