MIPS: drop incaip board
This is dead hardware and no one is interested in making the
necessary changes for upcoming features like generic board or
driver model.

A BDI2000 can be used for flash programming only -if the EBU swapping unit is enabled; otherwise it will not detect the -flash memory. But the EBU swapping unit is disadbled after reset, so -if you program some code to flash with the swapping unit on, it will -not be runnable with the swapping unit off. - -The consequence is that you have to write a pre-swapped image to -flash using the BDI2000. A simple host-side tool "inca-swap-bytes" is -provided in the "tools/" directory. Use it as follows: - - bash$ ./inca-swap-bytes <u-boot.bin >u-boot.bin.swp - -Note that the current BDI config file _disables_ the EBU swapping -unit for the flash bank 0. To enable it, (this is required for the -BDI flash commands to work) uncomment the following line in the -config file: - - ;WM32 0xb8000260 0x404161ff ; Swapping unit enabled - -and comment out - - WM32 0xb8000260 0x004161ff ; Swapping unit disabled - -Alternatively, you can use "mm 0xb8000260 <value>" commands to -enable/disable the swapping unit manually. - -Just for reference, here is the complete sequence of actions we took -to install a U-Boot image into flash. - - 1. ./inca-swap-bytes <u-boot.bin >u-boot.bin.swp - - 2. From BDI: - - mm 0xb8000260 0x404161ff - erase 0xb0000000 - erase 0xb0010000 - prog 0xb0000000 /tftpboot/INCA/u-boot.bin.swp bin - mm 0xb8000260 0x004161ff - go 0xb0000000 - - -Ethernet autonegotiation needs some time to complete. Instead of -delaying the boot process in all cases, we just start the -autonegotiation process when U-Boot comes up and that is all. Most -likely, it will complete by the time the network transfer is -attempted for the first time. In the worst case, if a transfer is -attempted before the autonegotiation is complete, just a single -packet would be lost resulting in a single timeout error, and then -the transfer would proceed normally. So the time that we would have -lost unconditionally waiting for the autonegotiation to complete, we -have to wait only if the file transfer is started immediately after -reset. We've verified that this works for all the clock -configurations. - -(C) 2003 Wolfgang Denk diff --git a/board/incaip/config.mk b/board/incaip/config.mk deleted file mode 100644 index e854f8e..0000000 --- a/board/incaip/config.mk +++ /dev/null @@ -1,16 +0,0 @@ -# -# (C) Copyright 2003 -# Wolfgang Denk, DENX Software Engineering, wd@denx.de. -# -# SPDX-License-Identifier: GPL-2.0+ -# - -# -# INCA-IP board with MIPS 4Kc CPU core -# - -# ROM version -CONFIG_SYS_TEXT_BASE = 0xB0000000 - -# RAM version -#CONFIG_SYS_TEXT_BASE = 0x80100000 diff --git a/board/incaip/flash.c b/board/incaip/flash.c deleted file mode 100644 index a786ac9..0000000 --- a/board/incaip/flash.c +++ /dev/null @@ -1,655 +0,0 @@ -/* - * (C) Copyright 2003 - * Wolfgang Denk, DENX Software Engineering, wd@denx.de. - * - * SPDX-License-Identifier: GPL-2.0+ - */ - -#include <common.h> -#include <asm/inca-ip.h> - -flash_info_t flash_info[CONFIG_SYS_MAX_FLASH_BANKS]; /* info for FLASH chips */ - -/* NOTE - CONFIG_FLASH_16BIT means the CPU interface is 16-bit, it - * has nothing to do with the flash chip being 8-bit or 16-bit. - */ -#ifdef CONFIG_FLASH_16BIT -typedef unsigned short FLASH_PORT_WIDTH; -typedef volatile unsigned short FLASH_PORT_WIDTHV; -#define FLASH_ID_MASK 0xFFFF -#else -typedef unsigned long FLASH_PORT_WIDTH; -typedef volatile unsigned long FLASH_PORT_WIDTHV; -#define FLASH_ID_MASK 0xFFFFFFFF -#endif - -#define FPW FLASH_PORT_WIDTH -#define FPWV FLASH_PORT_WIDTHV - -#define ORMASK(size) ((-size) & OR_AM_MSK) - -#if 0 -#define FLASH_CYCLE1 0x0555 -#define FLASH_CYCLE2 0x02aa -#else -#define FLASH_CYCLE1 0x0554 -#define FLASH_CYCLE2 0x02ab -#endif - -/*----------------------------------------------------------------------- - * Functions - */ -static ulong flash_get_size(FPWV *addr, flash_info_t *info); -static void flash_reset(flash_info_t *info); -static int write_word_intel(flash_info_t *info, FPWV *dest, FPW data); -static int write_word_amd(flash_info_t *info, FPWV *dest, FPW data); -static void flash_get_offsets(ulong base, flash_info_t *info); -static flash_info_t *flash_get_info(ulong base); - -/*----------------------------------------------------------------------- - * flash_init() - * - * sets up flash_info and returns size of FLASH (bytes) - */ -unsigned long flash_init (void) -{ - unsigned long size = 0; - int i; - - /* Init: no FLASHes known */ - for (i=0; i < CONFIG_SYS_MAX_FLASH_BANKS; ++i) { - ulong flashbase = (i == 0) ?
