From 7205e4075d8b50e4dd89fe39ed03860b23cbb704 Mon Sep 17 00:00:00 2001 From: wdenk Date: Wed, 10 Sep 2003 22:30:53 +0000 Subject: * Patches by Denis Peter, 9 Sep 2003: add FAT support for IDE, SCSI and USB * Patches by Gleb Natapov, 2 Sep 2003: - cleanup of POST code for unsupported architectures - MPC824x locks way0 of data cache for use as initial RAM; this patch unlocks it after relocation to RAM and invalidates the locked entries. * Patch by Gleb Natapov, 30 Aug 2003: new I2C driver for mpc107 bridge. Now works from flash. * Patch by Dave Ellis, 11 Aug 2003: - JFFS2: fix typo in common/cmd_jffs2.c - JFFS2: fix CFG_JFFS2_SORT_FRAGMENTS option - JFFS2: remove node version 0 warning - JFFS2: accept JFFS2 PADDING nodes - SXNI855T: add AM29LV800 support - SXNI855T: move environment from EEPROM to flash - SXNI855T: boot from JFFS2 in NOR or NAND flash * Patch by Bill Hargen, 11 Aug 2003: fixes for I2C on MPC8240 - fix i2c_write routine - fix iprobe command - eliminates use of global variables, plus dead code, cleanup. --- CHANGELOG | 27 + CREDITS | 6 + MAINTAINERS | 4 + board/mpl/common/common_util.c | 133 +--- board/mpl/common/common_util.h | 4 +- board/mpl/common/flash.c | 155 ++++- board/mpl/common/isa.c | 75 +- board/mpl/common/isa.h | 12 +- board/mpl/common/pci_parts.h | 9 +- board/mpl/common/piix4_pci.h | 2 +- board/mpl/mip405/cmd_mip405.c | 5 +- board/mpl/mip405/init.S | 24 +- board/mpl/mip405/mip405.c | 7 + board/mpl/mip405/mip405.h | 7 +- board/mpl/pip405/init.S | 159 +++-- board/mpl/pip405/pip405.c | 17 + board/mpl/pip405/pip405.h | 116 +--- board/sixnet/flash.c | 44 ++ board/sixnet/sixnet.c | 68 ++ common/cmd_doc.c | 11 +- common/cmd_fat.c | 159 ++++- common/cmd_jffs2.c | 2 +- cpu/mpc824x/Makefile | 6 +- cpu/mpc824x/drivers/i2c/Makefile | 84 --- cpu/mpc824x/drivers/i2c/Makefile_pc | 91 --- cpu/mpc824x/drivers/i2c/README | 104 --- cpu/mpc824x/drivers/i2c/i2c.c | 284 ++++++++ cpu/mpc824x/drivers/i2c/i2c.h | 309 --------- cpu/mpc824x/drivers/i2c/i2c1.c | 1243 ---------------------------------- cpu/mpc824x/drivers/i2c/i2c2.S | 52 -- cpu/mpc824x/drivers/i2c/i2c_export.h | 103 --- cpu/mpc824x/start.S | 17 +- cpu/pxa/mmc.c | 31 +- disk/part_dos.c | 21 +- disk/part_dos.h | 4 + fs/fat/fat.c | 184 +++-- fs/jffs2/jffs2_1pass.c | 96 ++- include/configs/AdderII.h | 4 +- include/configs/MIP405.h | 10 +- include/configs/PIP405.h | 12 +- include/configs/SXNI855T.h | 29 +- include/fat.h | 1 + include/jffs2/jffs2.h | 1 + include/part.h | 1 + post/cache_8xx.S | 5 +- post/ether.c | 4 +- post/uart.c | 3 +- 47 files changed, 1270 insertions(+), 2475 deletions(-) delete mode 100644 cpu/mpc824x/drivers/i2c/Makefile delete mode 100644 cpu/mpc824x/drivers/i2c/Makefile_pc delete mode 100644 cpu/mpc824x/drivers/i2c/README create mode 100644 cpu/mpc824x/drivers/i2c/i2c.c delete mode 100644 cpu/mpc824x/drivers/i2c/i2c.h delete mode 100644 cpu/mpc824x/drivers/i2c/i2c1.c delete mode 100644 cpu/mpc824x/drivers/i2c/i2c2.S delete mode 100644 cpu/mpc824x/drivers/i2c/i2c_export.h diff --git a/CHANGELOG b/CHANGELOG index 0cb827a..232a485 100644 --- a/CHANGELOG +++ b/CHANGELOG @@ -2,6 +2,33 @@ Changes for U-Boot 0.4.8: ====================================================================== +* Patches by Denis Peter, 9 Sep 2003: + add FAT support for IDE, SCSI and USB + +* Patches by Gleb Natapov, 2 Sep 2003: + - cleanup of POST code for unsupported architectures + - MPC824x locks way0 of data cache for use as initial RAM; + this patch unlocks it after relocation to RAM and invalidates + the locked entries. + +* Patch by Gleb Natapov, 30 Aug 2003: + new I2C driver for mpc107 bridge.

The host system that is running on MPC8240 - shall link the files listed here. The memory - location of driver routines shall take into - account of that driver routines need to run - in supervisor mode and they process I2C - interrupt. - -2. The host system is responsible for configuring - the MPC8240 including Embedded Utilities Memory - Block. All I2C driver functions require the - content of Embedded Utilities Memory Block - Base Address Register, EUMBBAR, as the first - parameter. - -3. Before I2C unit of MPC8240 can be used, - initialize I2C unit by calling I2C_Init - with the corresponding parameters. - - Note that the I2CFDR register shall be written - once during the initialization. If it is written - in the midst of transers, or after I2C STOPs or - REPEAT STATRs, depending on the data written, - a long reset time may be encountered. - -4. After I2C unit has been successfully initialized, - use the Application level API to send data or - receive data upon the desired mode, Master or - Slave. - -5. If the host system is also using the EPIC unit - on MPC8240, the system can register the - I2C_ISR with the EPIC including other - desired resources. - - If the host system does not using the EPIC unit - on MPC8240, I2C_Timer_Event function can - be called for each desired time interval. - - In both cases, the host system is free to provide - its own timer event handler and interrupt service - routine. - -6. The I2C driver routines contains a set - of utilities, Set and Get, for host system - to query and modify the desired I2C registers. - -7. It is the host system's responsibility of - queueing the I2C I/O request. The host - system shall check the I2C_ISR return code - for I2C I/O status. If I2C_ISR returns - I2CBUFFEMPTY or I2CBUFFFULL, it means - I2C unit has completed a I/O request - stated by the Application API. - -8. If the host system has more than one master - mode I2C unit I/O requests but doesn't want - to be intervented by being addressed as slave, - the host system can use the master mode - Application API with stop_flag set to 0 in - conjunction with is_cnt flag set to 1. - The first API call sets both stop_flag and - is_cnt to 0, indicating a START condition - shall be generated but when the end of - transaction is reached, do not generate a - STOP condition. Once the host system is - informed that the transaction has been - completed, the next Application API call - shall set is_cnt flag to 1, indicating a - repeated START condition shall be generated. - The last Application API call shall set - stop_flag - to 1. - -9. The I2C_Timer_Event function containes - a user defined function pointer. It - serves the purpose of providing the - host system a way to use its own event - handler instead of the I2C_ISR provided - here. diff --git a/cpu/mpc824x/drivers/i2c/i2c.c b/cpu/mpc824x/drivers/i2c/i2c.c new file mode 100644 index 0000000..7445a1c --- /dev/null +++ b/cpu/mpc824x/drivers/i2c/i2c.c @@ -0,0 +1,284 @@ +/* + * (C) Copyright 2003 + * Gleb Natapov + * Some bits are taken from linux driver writen by adrian@humboldt.co.uk + * + * Hardware I2C driver for MPC107 PCI bridge. + * + * See file CREDITS for list of people who contributed to this + * project. + * + * This program is free software; you can redistribute it and/or + * modify it under the terms of the GNU General Public License as + * published by the Free Software Foundation; either version 2 of + * the License, or (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
