Changes since U-Boot 1.0.0:
======================================================================
+* Patches by Stephan Linz, 11 Dec 2003:
+ - more documentation for NIOS port
+ - new struct nios_pio_t, struct nios_spi_t
+ - Reconfiguration for NIOS Development Kit DK1C20:
+ o move board related code from board/dk1c20
+ to board/altera/dk1c20
+ o create a new common source path board/altera/common
+ and move generic flash access stuff into it
+ o change/expand configuration file DK1C20.h
+ - Add support for NIOS Development Kit DK1S10
+ - Add status LED support for NIOS systems
+ - Add dual 7-segment LED support for Altera NIOS DevKits

+ *
+ * Each board can do what it likes here. But there are four "standard"

+ * _cwp_lolimit -Handles register window underflows.
+ * _cwp_hilimit -Handles register window overflows.
+ * _timebase_int -Increments the timebase.
+ * _def_xhandler -Default exception handler.
+ *
+ * _timebase_int handles a Nios Timer interrupt and increments the
+ * timestamp used for the get_timer(), reset_timer(), etc. routines. It
+ * expects the timer to be configured like the standard-32 low priority
+ * timer.
+ *
+ * _def_xhandler dispatches exceptions/traps via the external_interrupt()

-/*************************************************************************
- * Exception Vector Table
- *
- * This could have gone in the cpu soure tree, but the whole point of
- * Nios is customization -- and polluting the cpu source tree with
- * board-specific ifdef's really defeats the purpose, no? With this in
- * the board-specific tree, each board has the freedom to organize
- * vectors/traps, etc anyway it wants. The init code copies this table
- * to the proper location.
- *
- * Each board can do what it likes here. But there are four "standard"
- * handlers availble:
- *
- * _cwp_lolimit -Handles register window underflows.
- * _cwp_hilimit -Handles register window overflows.
- * _timebase_int -Increments the timebase.
- * _def_xhandler -Default exception handler.
- *
- * _timebase_int handles a Nios Timer interrupt and increments the
- * timestamp used for the get_timer(), reset_timer(), etc. routines. It
- * expects the timer to be configured like the standard-32 low priority
- * timer.
- *
- * _def_xhandler dispatches exceptions/traps via the external_interrupt()
- * routine. This lets you use the irq_install_handler() and handle your
- * interrupts/traps with code written in C.

2.1 Nios-specific Options/Settings
-----------------------------------
All configuration options/settings that are specific to Nios begin
-with "CONFIG_NIOS_" or "CFG_NIOS_". The following is a list of
-currently defined Nios-specific options/parameters. If any options
-are related to Standard-32 Nios SDK excalibur.h definitions, the
-related definition follows the description).
+with "CONFIG_NIOS_", "CFG_NIOS_", or "CFG_NIOS_CPU_".
+
+The configuration follows a two-stage process. In the first stage
+the NIOS CPU core will defined like defined in Alteras SOPC Builder.
+At this point we use the "CFG_NIOS_CPU_" defines exclusively. For
+more informations about all the definitions you have to setup see
+into current board configurations and doc/README.nios_CFG_NIOS_CPU.
+In second stage we bring the NIOS CPU configuration in relation to
+U-Boot configuration options/settings. The following is a list of
+currently defined Nios-specific options/parameters used inside of
+U-Boot. If any options are related to Standard-32 Nios SDK
+excalibur.h definitions, the related definition follows the
+description).
CONFIG_NIOS -- defined for all Nios-32 boards.
CFG_NIOS_CONSOLE -- the base address of the console UART.
- (standard-32: na_uart1_base).
+ (standard-32: nasys_uart_0 resp. na_uart1_base).
CFG_NIOS_FIXEDBAUD -- defined if the console UART PTF fixed_baud
parameter is set to '1'.
CFG_NIOS_TMRBASE -- the base address of the timer used to support
xxx_timer routines (e.g. set_timer(), get_timer(), etc.).
- (standard-32: na_lo_priority_timer2_base).
+ (standard-32: nasys_timer_1 resp. na_lo_priority_timer2_base).
CFG_NIOS_TMRIRQ -- the interrupt request (vector number) assigned to
- the timer. (standard-32: na_low_priority_timer2_irq).
+ the timer. (standard-32: nasys_timer_1_irq resp.
+ na_low_priority_timer2_irq).
CFG_NIOS_TMRMS -- the period of the timer in milliseconds.
but does not appear in the programmer's manual.
-4. BRAIN DAMAGE
+4. BOOT PROCESS
+---------------
+
+4.1 Boot process over GERMS
+---------------------------
+When the NIOS CPU catch a reset signal it will begin to be running
+code from CFG_NIOS_CPU_RST_VECT. Normally at this place it will
+find the GERMS monitor. That's the case for the generic NIOS CPU
+configuration "standard_32". When the GERMS monitor starts running,
+it performs important system initializations and then looks for
+executable code in flash, using the following steps:
+
+ 1. Examining the two bytes at CFG_NIOS_CPU_FLASH_BASE + 0x04000C.
+ 2. Examining the button 0 on the PIO CFG_NIOS_CPU_BUTTON_PIO.
+ 3. If the button is not pressed and the two bytes contain 'N'
+ and 'i', the monitor executes a CALL to location
+ CFG_NIOS_CPU_FLASH_BASE + 0x040000.
+ 4. If the code is not executed in step 3 or the code returns,
+ then prints an 8-digit version number to STDOUT and waits for
+ user commands from STDIN.
+
+In normal case, for "standard_32", STDIN and STDOUT are the first
+serial port.
+
+4.2 Return to GERMS command line
+--------------------------------
+During the boot process, the GERMS monitor checks for the existence
+of application software in flash memory. If found, the processor
+immediately executes the code. To return program execution to the
+GERMS monitor (that is, avoid running code stored in flash memory):
+
+ 1. Hold down CFG_NIOS_CPU_BUTTON_PIO, button number 0.
+ 2. Press then release the CPU reset button.
+ 3. Release CFG_NIOS_CPU_BUTTON_PIO, button number 0.
+
+
+5. BRAIN DAMAGE
----------------
This section describes some of the unfortunate and avoidable aspects
of working with the Nios CPU ... and some things you can do to
reduce your pain.
-4.1 GERMS doesn't work with Hyperterminal
+5.1 GERMS doesn't work with Hyperterminal
------------------------------------------
GERMS doesn't do CR/LF mapping that is compatible with Hyperterminal
(or minicom) -- geez. Regardless of you opion of Hyperterminal, this
sad design decision is remedied by using U-Boot.
-4.2 cygwin Incompatibility
+5.2 cygwin Incompatibility
---------------------------
The version of cygwin distributed with the nios GNUPro toolchain is
out-of-date and incompatible with the latest cygwin distributions.
The solution ... well, you can wait for Altera ... or build as
set of tools for linux.
-4.3 No native gcc
+5.3 No native gcc
------------------
I'm not sure how this one slipped through the cracks ... but it is
a real pain. Basically, if you want to build anything for the native
The solution ... same as above. Just download the gcc source from
Altera and build up a set of cross tools for your favorite linux
-distro.
+distro. Anybody who wants to use an already precompiled NIOS cross
+toolchain can it found in the CDK4NIOS project hosted by Source
+Forge at http://cdk4nios.sourceforge.net.
-4.4 Can't build default U-Boot
+5.4 Can't build default U-Boot
-------------------------------
By default, when you build U-Boot you will be building some native
tools along with the target elf, bin, and srec files. Without a
BTW, thats a 'zero' ... not the letter 'O'.
