+
+
+Changes:
+========
+
+Added Devices:
+==============
+
+Floppy support:
+---------------
+Support of a standard floppy disk controller at address CONFIG_SYS_ISA_IO_BASE_ADDRESS
++ 0x3F0. Enabled with define CONFIG_CMD_FDC. Reads a unformated floppy disk
+with a image header (see: mkimage). No interrupts and no DMA are used for this.
+Added files:
+- common/cmd_fdc.c
+- include/cmd_fdc.h
+
+SCSI support:
+-------------
+Support for Symbios SYM53C810A chip. Implemented as follows:
+- without disconnect
+- only asynchrounous
+- multiple LUN support (caution, needs a lot of RAM. define CONFIG_SYS_SCSI_MAX_LUN 1 to
+  save RAM)
+- multiple SCSI ID support
+- no write support
+- analyses the MAC, DOS and ISO pratition similar to the IDE support
+- allows booting from SCSI devices similar to the IDE support.
+The device numbers are not assigned like they are within the IDE support. The first
+device found will get the number 0, the next 1 etc. If all SCSI IDs (0..6) and all
+LUNs (8) are enabled, 56 boot devices are possible. This uses a lot of RAM since the
+device descriptors are not yet dynamically allocated. 56 boot devices are overkill
+anyway. Please refer to the section "Todo" chapter "block device support enhancement".
+The SYM53C810A uses 1 Interrupt and must be able of mastering the PCI bus.
+Added files:
+- common/cmd_scsi.c
+- common/board.c
+- include/cmd_scsi.h
+- include/scsi.h
+- board/pip405/sym53c8xx.c
+- board/pip405/sym53c8xx_defs.h
+
+ATAPI support (IDE changes):
+----------------------------
+Added ATAPI support (with CONFIG_ATAPI) in the file cmd_ide.c.
+To support a hardreset, when the IDE reset pin is not connected to the
+CONFIG_SYS_PC_IDE_RESET pin, the switch CONFIG_IDE_RESET_ROUTINE has been added. When
+this switch is enabled the routine void ide_set_reset(int idereset) must be
+within the board specific files.
+Only read from ATAPI devices are supported.
+Found out that the function trim_trail cuts off the last character if the whole
+string is filled. Added function cpy_ident instead, which trims also leading
+spaces and copies the string in the buffer.
+Changed files:
+- common/cmd_ide.c
+- include/ata.h
+
+ISO partition support:
+----------------------
+Added CD boot support for El-Torito bootable ISO CDs. The bootfile image must contain
+the U-Boot image header. Since CDs do not have "partitions", the boot partition is 0.
+The bootcatalog feature has not been tested so far. CD Boot is supported for ATAPI
+("diskboot") and SCSI ("scsiboot") devices.
+Added files:
+- disk/iso_part.c
+- disk/iso_part.h
+
+Block device changes:
+---------------------
+To allow the use of dos_part.c, mac_part.c and iso_part.c, the parameter
+block_dev_desc will be used when accessing the functions in these files. The block
+device descriptor (block_dev_desc) contains a pointer to the read routine of the
+device, which will be used to read blocks from the device.
+Renamed function ide_print to dev_print and moved it to the file disk/part.c to use
+it for IDE ATAPI and SCSI devices.
+Please refer to the section "Todo" chapter "block device support enhancement".
+Added files:
+- include/part.h
+changed files:
+- disk/dos_part.c
+- disk/dos_part.h
+- disk/mac_part.c
+- disk/mac_part.h
+- disk/part.c
+- common/cmd_ide.c
+- include/u-boot.h
+
+
+MC146818 RTC support:
+---------------------
+Added support for MC146818 RTC with defining CONFIG_RTC_MC146818. The ISA bus IO
+base address must be defined with CONFIG_SYS_ISA_IO_BASE_ADDRESS.
+Added files:
+- rtc/mc146818.c
+
+Standard ISA bus Keyboard support:
+----------------------------------
+Added support for the standard PC kyeboard controller. For the PIP405 the superIO
+controller must be set up previously. The keyboard uses the standard ISA IRQ, so
+the ISA PIC must also be set up.
+Added files:
+- board/pip405/kbd.c
+- board/pip405/kbd.h
+- board/pip405/pip405_isa.c
+- board/pip405/pip405_isa.h
+
+Chips and Technologie 69000 VGA controller support:
+---------------------------------------------------
+Added support for the CT69000 VGA controller.
+Added files:
+- board/pip405/video.c
+- board/pip405/video.h
+- board/pip405/vga_table.h
+
+
+Changed Items:
+==============
+
+Identify:
+---------
+Added the config variable CONFIG_IDENT_STRING which will be added to the
+"U_BOOT_VERSION __TIME__ DATE___ " String, to allows to identify intermidiate
+and custom versions.
+Changed files:
+- arch/powerpc/cpu/ppc4xx/start.s
+
+Firmware Image:
+---------------
+Added IH_OS_U_BOOT and IH_TYPE_FIRMWARE to the image definitions to allows the
+U-Boot update with prior CRC check.
+Changed files:
+- include/image.h
+- tools/mkimage.c
+- common/cmd_bootm.c
+
+Correct PCI Frequency for PPC405:
+---------------------------------
+Added function (in arch/powerpc/cpu/ppc4xx/speed.c) to get the PCI frequency for PPC405 CPU.
+The PCI Frequency will now be set correct in the board description in common/board.c.
+(was set to the busfreq before).
+Changed files:
+- arch/powerpc/cpu/ppc4xx/speed.c
+- common/board.c
+
+I2C Stuff:
+----------
+Added defined(CONFIG_PIP405) at several points in common/cmd_i2c.c.
+Added 16bit read/write support for I2C (PPC405), and page write to
+I2C EEPROM if defined CONFIG_SYS_EEPROM_PAGE_WRITE_ENABLE.
+Changed files:
+- arch/powerpc/cpu/ppc4xx/i2c.c
+- common/cmd_i2c.c
+
+Environment / Console:
+----------------------
+Although in README.console described, the U-Boot has not assinged the values
+found in the environment to the console. Corrected this behavior, but only if
+CONFIG_SYS_CONSOLE_IS_IN_ENV is defined.
+If CONFIG_SYS_CONSOLE_OVERWRITE_ROUTINE is defined, console_overwrite() decides if the
+values stored in the environment or the standard serial in/output should be
+assigned to the console. This is useful if the environment values are not correct.
+If CONFIG_SYS_CONSOLE_ENV_OVERWRITE is defined the devices assigned to the console at
+start-up time will be written to the environment. This means that if the
+environment values are overwritten by the overwrite_console() routine, they will be
+stored in the environment.
+Changed files:
+- common/console.c
+
+Correct bootdelay intepretation:
+--------------------------------
+Changed bootdelay read from the environment from simple_strtoul (unsigned) to
+simple_strtol (signed), to be able to get a bootdelay of -1.
+Changed files:
+- common/main.c
+
+Todo:
+=====
+
+Block device support enhancement:
+---------------------------------
+Consider to unify the block device handling. Instead of using diskboot for IDE,
+scsiboot for SCSI and fdcboot for floppy disks, it would make sense to use only
+one command ("devboot" ???) with a parameter of the desired device ("hda1", "sda1",
+"fd0" ???) to boot from. The other ide commands can be handled in the same way
+("dev hda read.." instead of "ide read.." or "dev sda read.." instead of
+"scsi read..."). Todo this, a common way of assign a block device to its name
+(first found ide device = hda, second found hdb etc., or hda is device 0 on bus 0,
+hdb is device 1 on bus 0 etc.) as well as the names (hdx for ide, sdx for scsi, fx for
+floppy ???) must be defined.
+Maybe there are better ideas to do this.
+
+Console assingment:
+-------------------
+Consider to initialize and assign the console stdin, stdout and stderr as soon as
+possible to see the boot messages also on an other console than serial.
+
+
+Todo for PIP405:
+================
+
+LCD support for VGA:
+--------------------
+Add LCD support for the CT69000
+
+Default environment:
+--------------------
+Consider to write a default environment to the OTP part of the EEPROM and use it
+if the normal environment is not valid. Useful for serial# and ethaddr values.
+
+Watchdog:
+---------
+Implement Watchdog.
+
+Files clean-up:
+---------------
+Following files needs to be cleaned up:
+- cmd_pip405.c
+- flash.c
+- pci_pip405.c
+- pip405.c
+- pip405_isa.c
+Consider to split up the files in their functions.
