+HCU4 Configuration Details
+
+Memory Bank 0 -- Flash chip
+---------------------------
+
+0xfff00000 - 0xffffffff
+
+The flash chip is really only 512Kbytes, but the high address bit of
+the 1Meg region is ignored, so the flash is replicated through the
+region. Thus, this is consistent with a flash base address 0xfff80000.
+
+The placement at the end is to be consistent with reset behavior,
+where the processor itself initially uses this bus to load the branch
+vector and start running.
+
+On-Chip Memory
+--------------
+
+0xf4000000 - 0xf4000fff
+
+The 405GPr includes a 4K on-chip memory that can be placed however
+software chooses. I choose to place the memory at this address, to
+keep it out of the cachable areas.
+
+
+Internal Peripherals
+--------------------
+
+0xef600300 - 0xef6008ff
+
+These are scattered various peripherals internal to the PPC405GPr
+chip.
+
+Chip-Select 2: Flash Memory
+---------------------------
+
+0x70000000
+
+Chip-Select 3: CAN Interface
+----------------------------
+0x7800000
+
+
+Chip-Select 4: IMC-bus standard
+-------------------------------
+
+Our IO-Bus (slow version)
+
+
+Chip-Select 5: IMC-bus fast (inactive)
+--------------------------------------
+
+Our IO-Bus (fast, but not yet use)
+
+
+Memory Bank 1 -- SDRAM
+-------------------------------------
+

+TODO:
+-----
+- Fix error: Waiting for PHY auto negotiation to complete..... TIMEOUT !
+ - Does not occur if both EMAC are connected
+- Fix RTS/CTS problem (HW?)
+ CONFIG_SERIAL_MULTI/CONFIG_SERIAL_SOFTWARE_FIFO hangs after
+ Switching to interrupt driven serial input mode
+- Make vxWorks start from u-boot. Possible reasons
+ - Does vxWorks need an entry for the Machine Check interrupt like this
+ tlbentry( 0x40000000, SZ_256M, 0, 1, AC_R|AC_W|AC_X|SA_G|SA_I ) ?
+
+Caveats:
+--------
+Errata CHIP_8: Incorrect Write to DDR SDRAM. (was not applied to sequoia.c)
+see hcu5.c.
+
+
+Memory Bank 0 -- Flash chip
+---------------------------
+
+0xfff00000 - 0xffffffff
+
+The flash chip is really only 512Kbytes, but the high address bit of
+the 1Meg region is ignored, so the flash is replicated through the
+region. Thus, this is consistent with a flash base address 0xfff80000.
+
+The placement at the end is to be consistent with reset behavior,
+where the processor itself initially uses this bus to load the branch
+vector and start running.
+
+On-Chip Memory
+--------------
+
+0xe0010000- 0xe0013fff CFG_OCM_BASE
+The 440EPx includes a 16K on-chip memory that can be placed however
+software chooses.
+
+Internal Peripherals
+--------------------
+
+0xef600300 - 0xef6008ff
+
+These are scattered various peripherals internal to the PPC440EPX
+chip.
+
+Chip-Select 2: Flash Memory
+---------------------------
+
+Not used
+
+Chip-Select 3: CAN Interface
+----------------------------
+0xc800000: 2 Intel 82527 CAN-Controller
+
+
+Chip-Select 4: IMC-bus standard
+-------------------------------
+
+0xcc00000: Netstal specific IO-Bus
+
+
+Chip-Select 5: IMC-bus fast (inactive)
+--------------------------------------
+
+0xce00000: Netstal specific IO-Bus (fast, but not yet used)
+
+
+Memory Bank 1 -- DDR2
+-------------------------------------
+
+0x00000000 - 0xfffffff # Default 256 MB
+
+PCI ??
+
+USB ??
+Only USB_STORAGE is enabled to load vxWorks
+from a memory stick.
+
+System-LEDs ??? (Analog zu HCU4 ???)
+
+Startup sequence
+----------------
+
+(cpu/ppc4xx/resetvec.S)
+depending on configs option
+call _start_440 _start_pci oder _start
+
+(cpu/ppc4xx/start.S)
+
+_start_440:
+ initialize register like
+ CCR0
+ debug
+ setup interrupt vectors
+ configure cache regions
+ clear and setup TLB
+ enable internal RAM
+ jump start_ram
+ which in turn will jump to start
+_start:
+ Clear and set up some registers.
+ Debug setup
+ Setup the internal SRAM
+ Setup the stack in internal SRAM
+ setup stack pointer (r1)
+ setup GOT
+ call cpu_init_f /* run low-level CPU init code (from Flash) */
+
+ call cpu_init_f
+ board_init_f: (lib_ppc\board.c)
+ init_sequence defines a list of function to be called
+ board_early_init_f: (board/netstal/hcu5/hcu5.c)
+ We are using Bootstrap-Option A
+ if CPR0_ICFG_RLI_MASK == 0 then set some registers and reboot
+ Setup the GPIO pins
+ Setup the interrupt controller polarities, triggers, etc.
+ Ethernet, PCI, USB enable
+ setup BOOT FLASH (Chip timing)
+ init_baudrate,
+ serial_init
+ checkcpu
+ misc_init_f #ifdef
+ init_func_i2c #ifdef
+ post_init_f #ifdef
+ init_func_ram -> calls init_dram board/netstal/hcu5/sdram.c
+ (EYE function removed!!)
+ test_dram call
+
+ * Reserve memory at end of RAM for (top down in that order):
+ * - kernel log buffer
+ * - protected RAM
+ * - LCD framebuffer
+ * - monitor code
+ * - board info struct
+ Save local variables to board info struct
+ call relocate_code() does not return
+ relocate_code: (cpu/ppc4xx/start.S)
+-------------------------------------------------------
+From now on our copy is in RAM and we will run from there,
+ starting with board_init_r
+-------------------------------------------------------
+ board_init_r: (lib_ppc\board.c)
+ setup bd function pointers
+ trap_init
+ flash_init: (board/netstal/hcu5/flash.c)
+ /* setup for u-boot erase, update */
+ setup bd flash info
+ cpu_init_r: (cpu/ppc4xx/cpu_init.c)

+ spi_init (r or f)??? (CFG_ENV_IS_IN_EEPROM)
+ env_relocated
+ misc_init_r(bd): (board/netstal/hcu5.c)
+ ethaddr mit serial number ergänzen
+ Then we will somehow go into the command loop
+
+Most of the HW specific code for the HCU5 may be found in
+include/configs/hcu5.h
+board/netstal/hcu5/*
+cpu/ppc4xx/*
+lib_ppc/*
+include/ppc440.h
+
+Drivers for serial etc are found under drivers/
+
+Don't ask question if you did not look at the README !!
+Most CFG_* and CONFIG_* switches are mentioned/explained there.
