Stefan Roese 5d812b8b4a ppc4xx: Enable support for > 2GB SDRAM on AMCC Katmai
Newer PPC's like 440SPe, 460EX/GT can be equipped with more than 2GB of SDRAM.
To support such configurations, we "only" map the first 2GB via the TLB's. We
need some free virtual address space for the remaining peripherals like, SoC
devices, FLASH etc.

Note that ECC is currently not supported on configurations with more than 2GB
SDRAM. This is because we only map the first 2GB on such systems, and therefore
the ECC parity byte of the remaining area can't be written.

Andrew Klossner dc4b0b38d4 Fix printf errors.
The compiler will help find mismatches between printf formats and
arguments if you let it.  This patch adds the necessary attributes to
declarations in include/common.h, then begins to correct the resulting
compiler warnings.  Some of these were bugs, e.g., "$d" instead of
"%d" and incorrect arguments.  Others were just annoying, like
int-long mismatches on a system where both are 32 bits.  It's worth
fixing the annoying errors to catch the real ones.

Andre Schwarz 846f1574dd fix system config overwrite @ MPC834x and MPC8313
During 83xx setup the "System I/O configuration register high" gets

Regarding to the MPC834x manual (Table 5-28 reve.1) bits 28+29 of SICRH
must keep their reset value regardless of configuration.

On my board (using RGMII) those bits are set after reset - yet it's

Becky Bruce 9973e3c614 Change initdram() return type to phys_size_t
This patch changes the return type of initdram() from long int to phys_size_t.
This is required for a couple of reasons: long int limits the amount of dram
to 2GB, and u-boot in general is moving over to phys_size_t to represent the
size of physical memory.  phys_size_t is defined as an unsigned long on almost
all current platforms.

This patch *only* changes the return type of the initdram function (in
include/common.h, as well as in each board's implementation of initdram).  It
does not actually modify the code inside the function on any of the platforms;
platforms which wish to support more than 2GB of DRAM will need to modify
their initdram() function code.

Build tested with MAKEALL for ppc, arm, mips, mips-el. Booted on powerpc
MPC8641HPCN.

  - Handle zero-length transfers appropriately. The user may send a
    zero-length SPI transfer with SPI_XFER_END set in order to
    deactivate the chip select after a series of transfers with chip
    select active. This is useful e.g. when polling the status
    register of DataFlash.

Haavard Skinnemoen d255bb0e78 SPI API improvements
This patch gets rid of the spi_chipsel table and adds a handful of new
functions that makes the SPI layer cleaner and more flexible.

Instead of the spi_chipsel table, each board that wants to use SPI
gets to implement three hooks:
  * spi_cs_activate(): Activates the chipselect for a given slave
  * spi_cs_deactivate(): Deactivates the chipselect for a given slave
  * spi_cs_is_valid(): Determines if the given bus/chipselect
    combination can be activated.

Not all drivers may need those extra functions however. If that's the
case, the board code may just leave them out (assuming they know what
the driver needs) or rely on the linker to strip them out (assuming
--gc-sections is being used.)

To set up communication parameters for a given slave, the driver needs
to call spi_setup_slave(). This returns a pointer to an opaque
spi_slave struct which must be passed as a parameter to subsequent SPI
calls. This struct can be freed by calling spi_free_slave(), but most
driver probably don't want to do this.

Before starting one or more SPI transfers, the driver must call
spi_claim_bus() to gain exclusive access to the SPI bus and initialize
the hardware. When all transfers are done, the driver must call
spi_release_bus() to make the bus available to others, and possibly
shut down the SPI controller hardware.

spi_xfer() behaves mostly the same as before, but it now takes a
spi_slave parameter instead of a spi_chipsel function pointer. It also
got a new parameter, flags, which is used to specify chip select
behaviour. This may be extended with other flags in the future.

This patch has been build-tested on all powerpc and arm boards
involved. I have not tested NIOS since I don't have a toolchain for it
installed, so I expect some breakage there even though I've tried
fixing up everything I could find by visual inspection.

I have run-time tested this on AVR32 ATNGW100 using the atmel_spi and
DataFlash drivers posted as a follow-up. I'd like some help testing
other boards that use the existing SPI API.

But most of all, I'd like some comments on the new API. Is this stuff
usable for everyone? If not, why?

Changed in v4:
  - Build fixes for various boards, drivers and commands
  - Provide common struct spi_slave definition that can be extended by
    drivers
  - Pass a struct spi_slave * to spi_cs_activate and spi_cs_deactivate
  - Make default bus and mode build-time configurable
  - Override default SPI bus ID and mode on mx32ads and imx31_litekit.

Changed in v3:
  - Add opaque struct spi_slave for controller-specific data associated
    with a slave.
  - Add spi_claim_bus() and spi_release_bus()
  - Add spi_free_slave()
  - spi_setup() is now called spi_setup_slave() and returns a
    struct spi_slave
  - soft_spi now supports four SPI modes (CPOL|CPHA)
  - Add bus parameter to spi_setup_slave()
  - Convert the new i.MX32 SPI driver
  - Convert the new MC13783 RTC driver

Changed in v2:
  - Convert the mpc8xxx_spi driver and the mpc8349emds board to the
    new API.

Stefan Roese bbeff30cbd ppc4xx: Remove superfluous dram_init() call or replace it by initdram()
Historically the 405 U-Boot port had a dram_init() call in early init
stage. This function was still called from start.S and most of the time
coded in assembler. This is not needed anymore (since a long time) and
boards should implement the common initdram() function in C instead.

This patch now removed the dram_init() call from start.S and removes the
empty implementations that are scattered through most of the 405 board
ports. Some older board ports really implement this dram_init() though.
These are:

csb272
csb472
ERIC
EXBITGEN
W7OLMC
W7OLMG

I changed those boards to call this assembler dram_init() function now
from their board specific initdram() instead. This *should* work, but please
test again on those platforms. And it is perhaps a good idea that those
boards use some common 405 SDRAM initialization code from cpu/ppc4xx at
some time. So further patches welcome here.

This patch makes the common 4xx ECC code really usable on 440GP style

Since the IBM DDR controller used on 440GP/GX/EP/GR is not register
compatible to the IBM DDR/2 controller used on 405EX/440SP/SPe/460EX/GT
we need to make some processor dependant defines used later on by the

This patch removes all SDRAM related defines from the PPC4xx headers
ppc405.h and ppc440.h. This is needed since now some 405 PPC's use
the same SDRAM controller as 440 systems do (like 405EX and 440SP).

It also introduces new defines for the equipped SDRAM controller based on
which PPC variant is used. There new defines are:

used on 405GR/CR/EP and some Xilinx Virtex boards.

used on 440GP/GX/EP/GR.

used on 440EPx/GRx.

Stefan Roese 64852d09e0 ppc4xx/NAND_SPL: Consolidate 405 and 440 NAND booting code in start.S
This patch consolidates the 405 and 440 parts of the NAND booting code
selected via CONFIG_NAND_SPL. Now common code is used to initialize the
SDRAM by calling initdram() and to "copy/relocate" to SDRAM/OCM/etc.
Only *after* running from this location, nand_boot() is called.

Please note that the initsdram() call is now moved from nand_boot.c
to start.S. I experienced problems with some boards like Kilauea
(405EX), which don't have internal SRAM (OCM) and relocation needs to
be done to SDRAM before the NAND controller can get accessed. When
initdram() is called later on in nand_boot(), this can lead to problems
with variables in the bss sections like nand_ecc_pos[].

Grant Erickson c821b5f120 ppc4xx: Enable Primordial Stack for 40x and Unify ECC Handling
This patch (Part 1 of 2):

* Rolls up a suite of changes to enable correct primordial stack and
  global data handling when the data cache is used for such a purpose
  for PPC40x-variants (i.e. CFG_INIT_DCACHE_CS).

* Related to the first, unifies DDR2 SDRAM and ECC initialization by
  eliminating redundant ECC initialization implementations and moving
  redundant SDRAM initialization out of board code into shared 4xx
  code.

* Enables MCSR visibility on the 405EX(r).

* Enables the use of the data cache for initial RAM on
  both AMCC's Kilauea and Makalu and removes a redundant
  CFG_POST_MEMORY flag from each board's CONFIG_POST value.

  - Removed, per Stefan Roese's request, defunct memory.c file for
    Makalu and rolled sdram_init from it into makalu.c.

With respect to the 4xx DDR initialization and ECC unification, there
is certainly more work that can and should be done (file renaming,
etc.). However, that can be handled at a later date on a second or
third pass. As it stands, this patch moves things forward in an
incremental yet positive way for those platforms that utilize this
code and the features associated with it.

Haavard Skinnemoen caf83ea888 avr32: Use the same entry point for reset and exception handling
Since the reset vector is always aligned to a very large boundary, we
can save a couple of KB worth of alignment padding by placing the
exception vectors at the same address.

Deciding which one it is is easy: If we're handling an exception, the
CPU is in Exception mode. If we're starting up after reset, the CPU is
in Supervisor mode. So this adds a very minimal overhead to the reset
path (only executed once) and the exception handling path (normally
never executed at all.)
