8bde63eb3f [MIPS] Rename Alchemy processor configs into CONFIG_SOC_*
CONFIG_SOC_AU1X00

  Common Alchemy Au1x00 stuff. All Alchemy processor based machines
  need to have this config as a system type specifier.

CONFIG_SOC_AU1000, CONFIG_SOC_AU1100, CONFIG_SOC_AU1200,
CONFIG_SOC_AU1500, CONFIG_SOC_AU1550

  Machine type specifiers. Each port should have one of aboves.

279726bd00 MPC86xx: Change traps.c to not reference non-addressable memory
Currently, END_OF_RAM is used by the trap code to determine if
we should attempt to access the stack pointer or not. However,
on systems with a lot of RAM, only a subset of the RAM is
guaranteed to be mapped in and accessible.  Change END_OF_RAM
to use get_effective_memsize() instead of using the raw ram
size out of the bd to prevent us from trying to access
non-mapped memory.

0e38c938ed DM9000 fix status check fail 0x6d error for trizeps board
According to the Application Notes of the DM9000, only the 2 bits 0:1 of
the status byte need to be checked to identify a valid packet in the fifo

But, The several different Application Notes do not all speak the same
language on these bits. They do not disagree, but only 1 Application Note
noted explicitly that only these 2 bits need to be checked.
Even the datasheets do not mention anything about these 2 bits.

Because the old code, and the kernel check the whole byte, I left this piece
untouched.

However, I tested all board/DM9000[A|E|EP] devices with this 2 bit check, so
it should work.

Notice, that the 2nd iteration through this receive loop (when a 2nd packet is
in the fifo) is much shorter now, compared to the older U-boot driver code,
so that we can maybe run into a hardware condition now that was never seen
before, or maybe was seen very unfrequently.

Additionaly added a cleanup of a stack variable.

a55d48174c [MIPS] lib_mips/time.c: Fix CP0 count register usage and timer routines
MIPS port has two problems in timer routines. One is now we assume CFG_HZ
equals to CP0 counter frequency, but this is wrong. CFG_HZ has to be 1000
in the U-Boot system.

The other is we don't have a proper time management counter like timestamp
other ARCHs have. We need the 32-bit millisecond clock counter.

This patch introduces timestamp and CYCLES_PER_JIFFY. timestamp is a
32-bit non-overflowing CFG_HZ counter, and CYCLES_PER_JIFFY is the number
of calculated CP0 counter cycles in a CFG_HZ.

STRATEGY:

* Fix improper CFG_HZ value to have 1000

* Use CFG_MIPS_TIMER_FREQ for timer counter frequency, instead.

* timer_init: initialize timestamp and set up the first timer expiration.
  Note that we don't need to initialize CP0 count/compare registers here
  as they have been already zeroed out on the system reset. Leave them as
  they are.

* get_timer: calculate how many timestamps have been passed, then return
  base-relative timestamp. Make sure we can easily count missed timestamps
  regardless of CP0 count/compare value.

* get_ticks: return the current timestamp, that is get_timer(0).

Most parts are from good old Linux v2.6.16 kernel.

v2:
- Remove FIXME comments as they turned out to be trivial.
- Use CP0 compare register as a global variable for expirelo.
- Kill a global variable 'cycles_per_jiffy'. Use #define CYCLES_PER_JIFFY
  instead.

6b52cfe16c Get rid of annoying/superfluous bad-checksum warning message
U-boot can complain a lot about 'checksum bad' when it is attached to the network.
It is annoying for ordinary users who start to doubt the network connection
in general when they see messages like this.

This is caused by the routine NetCksumOk() which cannot handle IP-headers longer
than 20 bytes. Those packages can be ignored anyway by U-boot, so we trash them
now before checking the checksum.

850ba7555d DM9000: Make driver work properly for DM9000A
The DM9000A network controller does not work with the U-boot DM9000x driver.
Analysis showed that many incoming packets are lost.

The DM9000A Application Notes V1.20 (section 5.6.1) recommend that the poll to
check for a valid rx packet be done on the interrupt status register, not
directly by performing the dummy read and the rx status check as is currently
the case in the u-boot driver.

When the recommended poll is done as suggested the driver starts working
correctly on 10Mbit/HD, but on 100MBit/FD packets come in faster so that there
can be more than 1 package in the fifo at the same time.

The driver must perform the rx-status check in a loop and read and handle all
packages until there is no more left _after_ the interrupt RX flag is set.

This change has been tested with DM9000A, DM9000E, DM9000EP.

a101361bfe DM9000: Add data bus-width auto detection.
The U-boot DM9000x driver contains a compile time bus-width definition for
the databus connected to the network controller.

This compile check makes the code unclear, inflexible and is unneccessary.
It can be asked to the network controller what its bus-width is by reading bits
6 and 7 of the interrupt status register.

The linux kernel already uses a runtime mechanism to determine this bus-width,
so the implementation below looks somewhat like that implementation.

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.

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.

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.

39b32be18c ppc4xx: Fix common ECC generation code for 440GP style platforms
This patch makes the common 4xx ECC code really usable on 440GP style
platforms.

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
driver.

ec724f883e ppc4xx: Change Kilauea to use the common DDR2 init function
This patch changes the kilauea and kilauea_nand (for NAND booting)
board port to not use a board specific DDR2 init routine anymore. Now
the common code from cpu/ppc4xx is used.

Thanks to Grant Erickson for all his basic work on this 405EX early
bootup.
